Comprehensive utilization of natural resources is an important area for the development of our country's science and technology. The comprehensive utilization of animal blood resources is an important component. In animal blood, red blood cells contain 92% protein and serum contains 78% protein. These proteins are composed of various amino acids such as methionine, lysine, tryptophan, histidine, leucine, arginine, and glycine. Animal blood is also rich in trace metal elements such as iron, copper, magnesium, zinc and other ions, and the blood can be a fund project: Changzhou New North District Science and Technology Bureau Innovation Fund (030305) -), male, Changzhou Jintanren, engineers, Engaged in research on modification of polymer materials.

Membranes and membranes made of blood can diagnose diseases. China is a country with rich animal blood resources. With the exception of a small amount of food, most of them are discarded in vain, wasting resources and contaminating the environment.

Therefore, the development and utilization of animal blood resources is an important research topic.

Using animal blood, after chemical treatment, bio-active derivatives are formed, and then cross-linked structures of polymer interpenetrating networks are formed with other ruthenium molecular materials, which can be used for seed coating materials. This paper focuses on the formation of a crosslinked network of blood polymer materials and other polymer materials. The viscoelastic properties of the polymer network structure were examined using a viscometer to characterize the crosslinked structure of the ruthenium molecule. At the same time, the use of the formed polymer network structure controls the release of active drugs for the release of agricultural pesticides and fungicides.

After standing overnight, samples were taken to test the viscoelastic properties of the crosslinked product.

1.5 Drug test for release of hematological high-molecular-weight seed coating agents The standard drug phenol is added to the seed coating agents AB-1 to AB-8, and the content of phenol in the seed coating agent is 1%. 10 mL of the seed coating agent is measured and poured onto a flat plate. On the glass (5cmXScm), Rao cast film. The resulting membrane was placed in a drug release device (see) for the determination of phenol release.

2 Results and discussion 1.2 Preparation of active derivative A component Add 500 g of fresh porcine blood to a 1 liter reaction pot, stir and sterilize with heating and boiling for 1 hour to obtain a blood gel. The obtained blood gel was transferred to a pulverizer for beating, and 12 niL of 30% aqueous hydrogen peroxide solution was added at the same time to oxidatively decolorize to obtain a yellow blood coagulation product which was blood solids and the water content was 80%. This gel-like blood solid matter was transferred to In a 1L reaction kettle, add 0.5, 1.0, 2.0, 2.5, 3.0, 3.5, 4.0, 5.0 mL of epoxy methacrylate (active compound containing reactive epoxy groups), mh methacrylic acid, and 0.5% of benzoyl peroxide was reacted for 2 hours under high-speed stirring at 50C to obtain a blood solid compound derivative A1 to A8 containing a reactive epoxide group having a semi-interpenetrating network structure. 1.3 Natural Polymer B Component Preparation 10g of sodium alginate was dissolved in 5 [>g of distilled water and stirred well to give a 2% solution of sodium alginate for blending with component A.

1.4 Preparation of Blood Polymer Seed Coating Agent The components A1A8 and B are blended in a ratio of 1/1 and are fully stirred to obtain the product AB1AB8. The pH is adjusted to 5,2.1 Preparation of the blood polymer interpenetrating network Animal blood contains Protein biogermanium molecules, when blended with methyl methacrylate and glycidyl methacrylate, form technetium polymers, tying biological proteins and introducing epoxy groups that can continue to react, epoxy groups The content of agglomerates increases as the amount of glycidyl monomer increases. Under acidic conditions, this group reacts with alginic acid to form an interpenetrating crosslinked network. The relationship between the structure and properties of the crosslinked network can be characterized by measuring the viscoelastic properties of the material.

2.2 Viscoelastic energy of interpenetrating crosslinked networks The viscometer can be used to determine the linear viscoelastic properties of a test sample under constant torsional vibration. In the dynamic case, a shear stress r is applied to the material: where is the amplitude of the shear stress, (1) is the frequency of the torsional vibration, and the shear strain y is a set of both the elastic part and the viscous part of the viscoelastic material and can be expressed by the following formula: Journal of Jiangsu Polytechnic University The year in which G' is the storage module, also known as the elastic modulus, is the loss modulus, also known as the viscous modulus. The composite modulus G'G-composite viscosity of the two sets will be used to characterize the change of the viscoelastic material with the shear frequency and the deformation process of the material network, which can be expressed by the following formula: The elastic modulus of the crosslinked network of animal blood molecules is given. The number changes with the change of the twisting frequency. The results show that with the increase of the epoxy group content of animal blood molecules, the formed cross-linked network is enhanced in elasticity and the viscous modulus is also increased, but the increase is smaller than G'. In addition, the composite viscosity of the material decreases with the increase of the shear frequency, indicating that the material has viscoelastic properties of the oxime molecule, and the higher the degree of cross-linking, the more viscous the composite viscosity. It has been shown that the intermolecular cross-linking network of tritiated molecules prepared from animal blood can be used to control the release of active drugs and can be used in agriculture to release various insecticides or fungicides for the coating treatment of plant seeds.

2.3 Interpenetrating network cross-linking structure Drug release Animal blood tritium molecules and other tritium molecules can form a complete interpenetrating cross-linked network for drug release. In this paper, the effect of cross-linked interpenetrating network with different degree of cross-linking to release phenol is studied. The test results show that when the degree of cross-linking is very low, the release rate of phenol is very fast, and it is released completely within 6 hours. When the degree of cross-linking is relatively low, the release of phenol can be delayed to 120 hours or even longer. Conclusions of this experiment 3 This paper reported the use of animal blood to prepare a polymer interpenetrating cross-linked network, and characterized the viscoelastic properties of the polymer using a viscometer, and conducted a preliminary study of the drug release behavior. The results of the study showed that with the increase in the degree of cross-linking of blood cross-linked molecules in animals, the elastic modulus of the tantalum molecules will increase, the complex viscosity will also increase, and the elastic modulus will be higher than the viscous modulus, indicating that animal blood Polymer network cross-linked structural integrity. The study on the release of phenol drugs confirmed that the release rate of phenol can be retarded by changing the cross-linking degree of the blood cross-linking network of animals, achieving the purpose of controlled release, and can be used for controlled release of agricultural pesticides and fungicides in agriculture. Seed preparations prepared from animal blood have been systematically tested on rice, wheat, corn, soybean, and rapeseed. The current results show that the seed coating does not affect the seed germination rate and can promote the effective growth of plant seeds. , To achieve the effect of increasing production.
