Problems solved by technology

[0003] Our country is now at the peak of urbanization, so a lot of construction projects are needed, so there is an urgent need for an economical and environmentally friendly building base material. However, if the current building base material is made of natural materials, the price will soar, while industrial buildings The base material has a great degree of environmental risk, and at the same time, the economy is not good, so we need to develop a building base material with better use effect

Abstract

The invention discloses a polymer material base material and a preparation process thereof, wherein the components of the formula comprise, by weight, 60-80 parts of hydrated calcium silicate, 6-14 parts of calcium sulfate, 10-15 parts of a polycarboxylic acid water reducing agent, 1-2 parts of a polyvinyl fluoride resin, 15-30 parts of polypropylene, 12-24 parts of ethyl cellulose, 6-16 parts of ammonium carbonate, and 1-3 parts of tetrabromobisphenol A. According to the present invention, the incombustibility of the polymer material base material achieves the grade A, the plate cannot burn when the fire disaster occurs, and no toxic smoke is generated; the electric conduction coefficient is low, such that the polymer material base material is the ideal insulating material; and the polymer material base material can maintain the stable performance and cannot recess and deform in the semi-open-air environment and the high temperature environment, can maintain the stable wet swelling rate and the stable dry shrinkage in the open-air and high-humidity areas, and further has advantages of excellent water resistance and excellent moisture resistance.

Description

technical field [0001] The invention relates to a base material, in particular to a polymer material base material and a preparation process thereof. Background technique [0002] Polymer materials, also known as polymer materials, are materials composed of high molecular compounds, that is, polymers. Most polymer materials, in addition to the basic component polymer, generally have various additives in order to obtain various practical properties or improve their molding and processing properties. The composition of the material and the ratio between the ingredients fundamentally guarantee the performance of the product, while various additives optimize the performance of the material to a certain extent; [0003] Our country is now at the peak of urbanization, so a lot of construction projects are needed, so there is an urgent need for an economical and environmentally friendly building base material. However, if the current building base material is made of natural mater...
