Abstract
The invention relates to an anti-compacting intensified polyester mixed construction material and the method for preparing the same. Raw material for said material and the proportion by weight are as follows: polyethylene terephthalate 650- 995, polyacrylamide (pam) 5- 50, glass fiber 0- 300, anti- oxidation agent 1- 10. The method comprises following steps: producing gel, mixing, drying and granulating. Compared with current technology, the invention adds a little hydrophilic resin containing amino into thermal plastic base material to form hydrogen bond with base material, which mproves immersion for PET in glass fiber and effectively increases PET anti-ompacting strength, especially the bending strength and module amount are dramatically increased, and the production cost is also reduced.
Description
Technical field
The present invention relates to blending and modifying engineering materials and preparation method thereof, relate in particular to blending engineering material of a kind of thermoplastics polyethylene terephthalate (PET) and polyacrylamide (PAM) and preparation method thereof.
Background technology
In view of the development of a series of industrial technology such as aircraft, shipbuilding, motor, light industry, weaving, petrochemical complex, electronic instrument department, material is had higher requirement.Making lightweight, high-strength, strong, novel material that machine-shaping is easy, is our current urgent task.This depends on the development of polymer kind on the one hand, depends on the other hand existing macromolecular material is carried out blend or filling-modified, to improve its every physical and mechanical properties index.It is simple that filling has complete processing as a kind of modifying plastics method, and processing units is less demanding, fills advantage such as back material price reduction and by widespread usage.
Polyethylene terephthalate (PET) is a kind of thermoplastics that has excellent physical and mechanical properties in wide temperature range, but because the PET crystallization rate is slow, the forming process difficulty, the molding temperature height, production cycle is long, impact property is poor, is used to make fiber in a large number, and has limited its application in the engineering plastics field.Generally, develop comparatively successful story by its processibility of method improvement and rerum naturas such as enhancing, filling, blend, as the Rynite of Du Pont (DuPont), the Ektar of Eastman, and Supreme Being people's FR-PET etc.
Polyacrylamide (PAM) is a kind of high molecular weight water soluble polymer, molecular weight is big, (weight average) can reach millions of even up to ten million, be insoluble to most of organic solvents, has good flocculence, reduce the frictional resistance between the liquid, improve processing characteristics, and good wetting property is arranged with glass surface.
Up to now, document is more about the report of blending and modifying PET preparation engineering plastics, but because the additive addition is big or the additive price is more expensive, causes PET to be restricted in practice.
Summary of the invention
Purpose of the present invention is exactly to provide a kind of for the defective that overcomes above-mentioned prior art existence can effectively improve shock strength, lower-cost punching-resistant reinforced polyester blending engineering material and preparation method thereof.
Purpose of the present invention can be achieved through the following technical solutions: a kind of punching-resistant reinforced polyester blending engineering material, adopt the raw material blend of following component and weight part content to form:
