Expect any one in particle, igelite particle.
Further, the textile fabric is any one in polypropylene fibre, acrylic fibers, terylene, polyamide fibre.
Textile fabric is used in the preparation of wood plastic composite by someone in the prior art, as fiber filling material
Used, the use characteristic of wood plastic composite can be lifted, achieve good effect, but generally to be added in the method big
The chemical solvent of amount, production cost is not only increased, while be also possible to that a large amount of waste liquids can be produced, secondary pollution is caused to environment.
Improvement is optimized to the reuse method of textile fabric to this present invention, textile fabric is carried out at crushing using low temperature
Reason, avoids solvent in the prior art（Organic solvent, resin etc.）Use, reduce cost, protect environment, then carry out
Special stir process, wherein first having carried out a stir process, in high temperature and mixed liquor under the treatment conditions of solvent, spin
Melting adhesion occurs between textured fiber particle, while again under conditions of high-speed stirred processing, textile fabric particle is constantly disperseed
Upset, ultimately form substantial amounts of small granule, and carried out secondary stirring treatment, reduce the environment temperature of stirring, now
The textile fabric particle of bulk is in half plastifying state, application60The processing of Co- gamma-ray irradiations can promote blended liquid modified
Polymerization between textile fabric, the relative molecular mass of the textile fabric particle of bulk is improved, enhances its mechanical strength characteristics,
Improve its filling using effect in wood plastic composite.
The present invention has advantages below compared with prior art：
The present invention has carried out special processing to textile fabric, effectively improves the use quality that its filling recycles, well
Mechanical characteristic and the life-span of wood plastic composite are improved, there is good economic benefit and practical value, it is fine for existing weaving
