Description
Technical field
The present invention relates to glass fibre, particularly a kind of degradable glass fibre.
Background technology
At present on the market the most general glass fibre be C glass fibres, E glass fibres, ECR glass fibres and by this
A little glass constitute derived glass fibre, and these glass fibres are steady due to its excellent electrical insulation capability, high rigidity, size
Qualitative strong, lightweight, cost is relatively low, raw material are easy to get etc. is mainly used in the field of electronic materials for requiring relatively harsh.
The Main Ingredients and Appearance for being mainly used in the glass fibre of electronic applications at this stage is：
(1) Main Ingredients and Appearance of C glass is：SiO2For 60~68%, Al2O3It is 10-15% for 5~10%, CaO+MgO,
Na2O+K2O is 10-16%；
(2) the general composition of E glass is SiO2For 52~56%, B2O3For 5~12%, Al2O3It is for 12~16%, CaO
16-19%, MgO are 3-6% (U.S.Pat No.2,334,961)；
(3) ECR glass is as the glass fibre promoted, and is one kind without boron fluoride-free glass, the general composition of ECR glass
For SiO2For 55-62%, Al2O3For 12-16%, CaO is 20-25%, and MgO is 2.5-6%, Na2O+K2O is 0-1.5%.
And three of the above glass fibre all has common feature, intensity is high, non-degradable, its degradation time it is estimated that
Up to centuries even more than one thousand years, and electronic material update speed is ultrafast now, and substantial amounts of " electronic waste " is caused sternly
The environmental pollution of weight, then just seem most important using degradation material in electronic product.
In terms of the application study and exploitation of ecological environment material nd, in order to eliminate " white pollution ", the later stage nineties, completely
Degradation plastic comes out.Mainly have at present：Aggretion type photodegradable plasticses, aggretion type biodegradable plastic and the life of full starch thermoplastic
Thing degradative plastics.But except above-mentioned degradative plastics on agricultural mulching in addition to having successfully report, in other respects, be particularly
It is less in the report of the application aspect of packaging material.This poor mechanical property mainly due to these materials, cost in itself is relative
Caused by higher.Therefore, the mechanical property for improving degradation plastic is the another disaster that degradation material application field needs to solve
Topic.
Above-mentioned degradation material some problems for encountering in application study and exploitation, can be by the approach of composite
Solve, but condition is that must have the high intensity and degradable fiber for meeting above-mentioned each application environment requirement.
In terms of bio-medical material, artificial implants in vivo generally includes permanently to use implant (such as artificial pass
Section, knee joint and cardiac valves etc.) and temporary use implant (such as bone fracture internal fixation material, bone impairment renovation material and medicine
Thing slow-release material etc.).Medical material system of the artificial implants in vivo requirement permanently used with good biological stability
Make, and the temporary artificial implants in vivo used, it is more suitable using the degradable absorbability medical material of medical bio.
The content of the invention
