Abstract

The invention discloses a preparation process of heat-preservation and heat-insulation gypsum for a composite multifunctional wall. The preparation process comprises the following production steps: preparing raw materials, crushing desulfurized gypsum, mixing reinforcing materials, mixing additives and preparing gypsum powder. According to the preparation process of the heat-preservation and heat-insulation gypsum for the composite multifunctional wall, a special reinforcing material is arranged, modified diatomite in the reinforcing material can improve the physical structure of a finished gypsum wall surface and increase the micropore structure of the gypsum wall surface, strong water-retention and heat-insulation performance is achieved, coal ash is beneficial to adsorption of peculiar smell in indoor space, the indoor environment is improved, and the reduction of formaldehyde pollution is promoted; and polypropylene fibers are good flame retardant fibers, the good flame retardant fireproof performance for the wall body is endowed, the binding force between the gypsum can be increased, the structural strength of the gypsum wall surface is improved, and a toxic substance is not added or produced during the production process.

Description

technical field [0001] The invention relates to the technical field of gypsum production, in particular to a heat-insulating gypsum preparation process for composite multifunctional walls. Background technique [0002] The Outline of the Building Materials Industry Development Plan proposes to vigorously develop new types of wall materials that are environmentally friendly and energy-saving.
