Water absorbing and toughening material for plastic moulding

Abstract

The invention discloses a water absorbing and toughening material for plastic moulding. Raw materials comprise 10-20 weight parts of flexibilizer, 50-60 weight parts of inorganic silicate material, 0.5-1.5 weight parts of coupling agent and 20-30 weight parts of resin. The flexibilizer is a butadiene-styrene, styrene-butadiene or acrylonitrile-styrene copolymer; the strengthening agent is powdered steatile or montmorillonite; the inorganic silicate is one or more selected from magnesium silicate, calcium silicate, sodium silicate and barium silicate; and the coupling agent is a silane coupling agent. The invention provides a water absorbing and toughening material for plastic moulding processing, which can absorb water, enhance toughness and increase product quality, and solves a problem that product quality is influenced by fragile and damped raw materials in a prior plastic moulding processing. Besides, the material can be used in a plurality of plastic moulding processes, such as plastic tubing, injection moulding and hollow blow molding moulding, to realize functions of toughening and bubble elimination.

Description

technical field [0001] The invention relates to a water-absorbing and toughening material for plastic molding. Background technique [0002] In the molding and processing of plastic products, some materials often have reduced toughness and increased brittleness due to their own molecular structure, repeated recycling and granulation by thermal decomposition, and the addition of fillers, which affect product quality. Particles, mixed with some water in the material, and some materials are very easy to absorb moisture in the air because of their molecular structure is a strong polar molecule, resulting in difficulties in the plastic molding process of these materials and unqualified performance of the finished product. , the more typical ones are water-stretched granulated recycled materials and highly polar plastic raw materials such as PS, PA, and ABS. These materials are most commonly used in plastic molding processes for plastic pipes and injection molded products. Cont...

[0002]In the molding process of plastic products, some materials often have reduced toughness and increased brittleness due to their own molecular structure, repeated recycling and granulation, thermal decomposition, and fillers. In terms of product quality, some materials are granulated with water, and some water is mixed in the materials, and some materials are highly polar molecules because of their molecular structure, which can easily absorb moisture in the air, resulting in these materials in the air. Difficulties in the plastic molding process and unqualified performance of the finished products, the typical ones are recycled recycled materials granulated by water slabs and highly polar plastic raw materials such as PS, PA, ABS, etc.
