Abstract

The invention discloses a composite material of dried-method plaster and building plaster with weight rate at 1: 0.75-1.0, which has the advantages of light weight and high strength to manufacture plaster wall board and render plaster with thermal insulation, sound absorption, flame-proof and water-proof property.

Description

technical field [0001] The design building material of the invention specifically refers to a mixture of dry-process fluorine gypsum and building gypsum that can be used to make products such as gypsum wallboard and plaster plaster. Background technique [0002] Dry fluorine gypsum (namely type II anhydrous fluorine gypsum, the composition is CaSO 4 ) and building gypsum (also known as hemihydrate gypsum, the composition is ) are high-quality building materials. Dry fluorine gypsum can quickly become a hydration hardening body under the excitation of admixtures, and has hydraulic characteristics and certain strength, but it has a longer solidification time and a larger dry density than building gypsum; building gypsum can quickly water Chemical hardening, but poor water resistance. Contents of the invention [0003] The technical problem to be solved in the present invention is to propose a dry-process fluorine gypsum and building gypsum mixture, which is composed of t...
