Macromolecular nano coating material composite slurry

Abstract

The present invention relates to one kind of nanometer composite polymer paint slurry, which consists of water 30 wt%, dispersant 0.6 wt%, nanometer polymer assistants 1 wt%, sodium bentonite 2 wt%. heavy calcium carbonate 45 wt%, wollastonite 10 wt%, kaolin 10 wt% and titanium white powder 0-5 wt%, where, the nanometer polymer assistants includes aluminum sulfate 20 wt%, sodium silicate 50 wt%, pentaerythritol 20 wt%, hydroxypropyl methyl cellulose 2.5 wt% and sodium fluosilicate 7.5 wt%. The nanometer composite polymer paint slurry has the crystal structure of the components maintained and narrow size distribution, and can form coating with fire resistance, no smoke in fire, high adhesion to inorganic base material and other advantages.

Description

technical field [0001] The invention belongs to the field of chemical raw materials, in particular to a composite slurry of polymer nano-coatings. Background technique [0002] In the existing production process of latex paint, in order to reduce costs and maintain product quality at the same time, it is often only achieved by increasing the amount of titanium dioxide and emulsion, which greatly increases the cost of latex paint; The various powders that account for the largest proportion of latex paint ingredients are regarded as cheap materials, which are only used to reduce costs. some performance. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a kind of polymer nano-coating composite slurry, which can be used to produce latex paint and can overcome the problem that only by increasing the usage amount of titanium dioxide and latex in the existing latex paint production process, high gloss and performance can be produced. The lack ...

[0002]In the existing production process of latex paint, in order to reduce the cost while maintaining the product quality, it is often only possible to increase the amount of titanium dioxide and emulsion This will greatly increase the cost of latex paint; and the various powders that account for the largest proportion in latex paint ingredients are regarded as cheap materials, which are only used to reduce costs and are considered to have almost no special functions. Reduce costs by reducing the quality of powder, and greatly change some properties of latex paint
