Abstract
The invention provides a kind of method for preparing biological based elastomeric using discarded collagen.This method will be prepared for skin powder after the crushing of discarded skin bit first, then plasticization and modification is carried out to skin powder, it is prepared for directly carrying out the skin powder raw material of injection mo(u)lding, by carrying out injection mo(u)lding under suitable conditions, the elastomeric material of excellent mechanical performances is obtained under conditions of without any crosslinking agent.The present invention carries out plasticization and modification to skin powder from water, ethylene glycol, polyethylene glycol, reduces the melt temperature of skin powder, makes skin powder that conventional Shooting Technique can be used directly and be processed.Biological based elastomeric prepared by the method has good resilience, pliability, thermoplasticity and biodegradability, has market potential application prospect the aspects such as disposable rubber, degradable elasticity membrane material are prepared.
Description
Technical field
The present invention relates to Biodegradable material preparation field, in particular to a kind of biodegradable, can thermoplastic,
Environmentally friendly bio-based method for producing elastomers.
Background technology
Hide glue raw material are the accessory substances for mostling come from animal husbandry, and the content of the Animal Skin Collagen such as pig, ox, sheep is up to 90%
More than, be at present maximum in the world renewable biomass resources, and with 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 current process hides is produced
Industry is the maximum application of collagen, about consumes the 50% of collagen total amount every year, but the collagen only less than 20% is most
Finished leather is converted into eventually.Therefore, the generation of a large amount of collagen discarded objects, 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 for discarding collagen, such as by skin
Directly composite is made in blending to powder with synthesis macromolecular material, and as 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 to occur being separated, and material mechanical performance is poor, fails to reach expected effect
Really.At present collagen sill is widely used in biomedicine and biological technical field, but its requirement to collagen compared with
The melt temperature of height, extraction process complexity, and collagen is too high to be difficult to shaping, seriously limits its application.Therefore, a side
Face needs the Land use systems of the collagen for finding more economic, on the other hand will then consider the method pair by physics or chemistry
Which is modified, so as to improving its processing characteristics and extending its application.
The purpose of the present invention is the shortcomings and deficiencies existed for prior art, directly by the use of discarded collagen as original
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 characteristics, and processing and forming is carried out using conventional injection molding process, prepare with excellent mechanics
The bio-based elastomeric material of performance.So far, there is not yet with regard to the document of biological based elastomeric or special is prepared using skin powder
Profit report.
The content of the invention
A kind of method for preparing biological based elastomeric using discarded collagen, it is as follows which prepares feature：

20 ~ 30 h of freeze-drying under part, crushes, and screens through the sieve plate of 120 mesh, skin powder is obtained, preserve under drying condition；
（2）It is 1 according to mass ratio by skin powder and plasticizer：（0.4~2）, it is well mixed, after skin powder is fully swelling, by its powder
It is broken, obtain modified skin powder；
（3）Modified skin powder is directly processed under suitable injection temperature using injection molding process, wherein being molded
Mould temperature is 30 ~ 40 DEG C, and injection pressure is 650 ~ 900 bar, and the dwell time is 8 ~ 12 s；
Described discarded skin bit is raw hide, graywall, the one kind in the leftover pieces of sour skin；
Described plasticizer is water, ethylene glycol, the one kind in the polyethylene glycol of molecular weight 200 ~ 800；
Described injection temperature is 90～180 DEG C；
Described biological based elastomeric is using collagen is discarded for raw material, with biodegradable, eco-friendly advantage.
