Abstract
The present invention discloses a polyester molding compound imitating marble and a preparation method thereof. The polyester molding compound imitating marble is prepared by mixing and compounding unsaturated polyester, a low shrink additive agent, graded hydrated alumina, an initiator, a demoulding agent, a thickening agent, vinylon fibre, a viscosity reductant and alkali-free short cutting glass fiber in certain proportion. The polyester molding compound has marbleized porcelain outer surface and is not easy to be damaged, so the polyester molding compound can satisfy people's requirements for variety and individuation of products. In addition, the polyester molding compound can be used for fabricating insulation products of high and low voltage electrical apparatus.
Description
(1) technical field
The present invention relates to a kind of engineering plastics and preparation method thereof.Be to have marblized unsaturated polyester die plastic and preparation method thereof specifically.
(2) background technology
In electric utility, used insulated product mainly contains two kinds of ceramic material and thermosetting resines on the high and low voltage electrical equipment.The former is a stupalith, is difficult for wearing out, but fragile, fragile, gradually by the latter---thermosetting resin replaces.But the plastic insulation goods all are monotones again, or are single black, or are single redness or true qualities.The plastic insulation goods of this monotone can not satisfy variation and the personalized requirement of people to product.Therefore, just need to research and develop a kind of stupalith appearance that both had, have specific tenacity height, high-impact, high insulating property and non-damageable polyester molding compound again, to be used to make the insulated product on the high and low voltage electrical equipment.
(3) summary of the invention
The object of the present invention is to provide a kind of polyester molding compound of marbleize.This polyester molding compound had both had marblized porcelain appearance, and was not fragile again, can satisfy people to the variation of product, personalized requirement.
Another object of the present invention provides a kind of method for preparing the marbleize moulding compound.
Above-mentioned purpose of the present invention is realized by following technical solution:
The polyester molding compound of marbleize of the present invention, form by the raw material of following parts by weight:

Prepare the method for the polyester molding compound of above-mentioned marbleize, may further comprise the steps successively:
(1) earlier unsaturated polyester, low shrinkage additive, viscosity-depression agent and initiator are poured in the kneading machine under 15～40 ℃ temperature mixing 40～60 minutes;
(2) add hydrated aluminum oxide, thickening material, releasing agent and the vinylon fiber of grating again, under 15～40 ℃ temperature mixing 50～70 minutes;
(3) last, add the alkali-free short glass fiber, under 25～40 ℃ temperature mixing 4～8 minutes, make the polyester molding compound of marbleize of the present invention.
Adopt such scheme, have the following advantages:
Because the polyester molding compound of marbleize of the present invention is to have added a certain proportion of vinylon fiber in the conventional formulation of preparation moulding compound, and forms through mixing.With the high and low voltage electrical equipment insulated product that this moulding compound is made through moulding, its appearance has marbling, and is smooth, smooth.Both had marblized porcelain appearance, had specific tenacity height, high-impact, high insulating property again, not fragile.Thereby satisfied variation and the personalized requirement of people to product.
