Abstract
The present invention provides a kind of methods for preparing biological based elastomeric using discarded collagen.This method is prepared for skin powder after first crushing discarded skin bit, then plasticization and modification is carried out to skin powder, it is prepared for directly carrying out the skin powder raw material of injection molding, by carrying out injection molding under suitable conditions, the elastomeric material of excellent mechanical performances is obtained under conditions of not adding any crosslinking agent.The present invention selects water, ethylene glycol, polyethylene glycol to carry out plasticization and modification to skin powder, reduces the melting temperature of skin powder, makes skin powder that conventional Shooting Technique can be used directly and processed.The biological based elastomeric of this method preparation has good resilience, flexibility, thermoplasticity and biodegradability, there is market potential application prospect in terms of preparing disposable rubber product, degradable elasticity.
Description
Technical field
The present invention relates to biodegradable material preparation field, in particular to a kind of biodegradable, can thermoplastic,
Environmentally friendly biology base method for producing elastomers.
Background technique
Hide glue raw material are the by-products for mostling come from animal husbandry, and the contents of the Animal Skin Collagens such as pig, ox, sheep is up to 90%
More than, be current renewable biomass resources maximum in the world, and as the improvement of people's living standards, its yield also by
Year increases.Collagen is natural macromolecular material, possesses unique texture and property that synthesis macromolecule hardly matches, and process hides at present produces
Industry is the maximum application field of collagen, about consumes the 50% of collagen total amount every year, however the collagen only less than 20% is most
It is converted into finished leather eventually.Therefore, the generation of a large amount of collagen wastes has for researching and developing its non-process hides and utilizing
Significance.
Many research workers have carried out beneficial exploration sex work to the recycling of discarded collagen, such as by skin
Powder is directly blended with synthesis high molecular material and composite material is made, and since the polarity of collagen itself is stronger, skin powder is easily tied in addition
Block, the poor compatibility of the two cause synthetic composite material appearance mutually to separate, and material mechanical performance is poor, fails to reach expected effect
Fruit.Collagen sill is widely used in biomedical and field of biotechnology at present, but its requirement to collagen compared with
The melting temperature of height, extraction process complexity, and collagen is excessively high to be difficult to form, and is seriously limited its application.Therefore, a side
Face needs to find the Land use systems of more economic collagen, on the other hand then to consider the method pair by physics or chemistry
It is modified, and so as to improve its processing performance and extends its application field.
It is an object of the present invention in view of the defects existing in the prior art with deficiency, directly using discarded collagen as former
Material is prepared skin powder by way of freeze-drying and physical crushing, and is made using renewable resource water, ethylene glycol, polyethylene glycol
For plasticizer, improve its processing performance, and carry out processing and forming using conventional injection molding process, preparation has excellent mechanics
The biology base elastomeric material of performance.So far, there is not yet about the document for preparing biological based elastomeric using skin powder or specially
Benefit report.
Summary of the invention
A method of biological based elastomeric being prepared using discarded collagen, preparation feature is as follows:
(1) discarded skin bit is sufficiently washed to removal surface smut with distilled water, after pretreatment -40 DEG C~-60
It is freeze-dried 20 ~ 30 h under the conditions of DEG C, crushes, is screened by the sieve plate of 120 mesh, skin powder is made, is saved under drying condition；
(2) it is 1:(0.4 ~ 2 according to mass ratio by Pi Fenyu plasticizer), it is uniformly mixed, after skin powder is sufficiently swollen, by it
It crushes, obtains modified skin powder；
(3) modified skin powder is directly processed under suitable injection temperature using injection molding process, wherein
Injection mould temperature is 30 ~ 40 DEG C, and injection pressure is 650 ~ 900 bar, and the dwell time is 8 ~ 12 s；
The discarded skin bit is one of former skin, graywall, the leftover pieces of sour skin；
The plasticizer is one of water, ethylene glycol, the polyethylene glycol of molecular weight 200 ~ 800；
