Outer wall heat-insulating homogenous plate and preparation process thereof

Abstract

The invention relates to an outer wall heat-insulating homogenous plate and a preparation process thereof, and belongs to the field of heat-insulating building materials. The outer wall heat-insulating homogenous plate comprises the following raw materials in parts by weight: expanded perlite, light molybdenum oxide, a ceramic powder, a zinc oxide powder, polypropylene short fiber, a mica powder,a calcium powder, a water repellent, a performance additive, bentonite, glass fiber, EPS granules, a silicon powder, an organosilicon waterproof agent, cement, calcined desulfurized gypsum, a flame retardant, a water-reducing agent, an adhesion agent, a foaming agent and water. Compared with the common heat-insulating material, the outer wall heat-insulating homogenous plate has the advantages that the properties are greatly improved, the strength, the heat-insulating effect, the fire resistance, the water resistance and the like of the material are greatly improved, and high tension resistance is achieved.

Description

Technical field: [0001] The invention belongs to the field of thermal insulation building materials, and in particular relates to an external wall thermal insulation homogeneous board and a preparation process thereof. Background technique: [0002] Insulation materials are generally materials with a thermal coefficient less than or equal to 0.12. The development of thermal insulation materials is rapid, and the use of good thermal insulation technology and materials in industry and construction can often achieve twice the result with half the effort. [0003] The traditional thermal insulation materials are mainly to increase the gas phase void ratio and reduce the thermal conductivity and conductivity coefficient. In order to increase convective heat transfer and radiation heat transfer in the use environment, fiber-based thermal insulation materials must have a thicker coating; while profile-based inorganic thermal insulation materials need to be assembled and constructe...
