Abstract

The invention belongs to the technical field of polymer composite materials, and relates to a water-absorbing reinforcing material for plastic molding, a preparation method and application thereof. The water absorption enhancer is polymerized from monomer A, monomer B, monomer C and monomer D, and its structure is shown in formula (1): wherein, the monomer A is γ-chloropropyl Trichlorosilane; the monomer B is cyclopentyltrimethoxysilane or isobutyltrimethoxysilane; the monomer C is methyl methacrylate; the monomer D is ethylenediamine; the chemical formula is; (C5H9 )14(Si8O12)2(C4H6O2)x(C10H16N2O2)y or (C4H9)14(Si8O12)2(C4H6O2)x(C10H16N2O2)y, where x=1-1000, y=1-1000. The water absorption enhancer of the present invention contains POSS structural units, which not only avoids the performance degradation of the material caused by water absorption, but also improves the specific performance of the material.

Description

technical field [0001] The invention belongs to the technical field of polymer composite materials, and relates to a water-absorbing reinforcing material for plastic molding, a preparation method and application thereof. Background technique [0002] In plastic rod granulation and molding processing, some materials often have a decrease in strength due to their own molecular structure, repeated recycling and granulation by thermal decomposition, and the addition of fillers, which affects product quality, and some materials are granulated by water rods. , Some water is mixed in the material, which causes difficulties in granulation and molding processing of these materials and unqualified performance of the finished product. Typical recycled materials are water-stretched granulated recycled materials. [0003] In "Water-absorbing Agents Used in Plastic Molding Processing and Its Preparation Method", Chen Mingzhong et al. processed and granulated inorganic oxides and carrier r...
