Architectural insulated board and preparation method thereof

Abstract

The invention discloses an architectural insulated board and belongs to the technical field of building materials. The architectural insulated board comprises the following raw materials in parts by weight: 6-8 parts of polyvinyl acetate emulsion, 1-2 parts of butyl rubber, 5-10 parts of ceramic fibers, 4-8 parts of steel fibers, 15-20 parts of glass wool, 5-7 parts of expanded vermiculite, 5-7 parts of sepiolite powder, 12-15 parts of diatomite, 7-9 parts of talcum powder, 2-4 parts of asphalt, 1-3 parts of sodium silicate, 0.1-0.2 part of a light stabilizer, 0.1-1 part of a water reducing agent and 1-2 parts of a curing agent. The invention further discloses a preparation method of the architectural insulated board. The architectural insulated board disclosed by the invention is simple in preparation and high in strength and has excellent thermal insulation capacity.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a building thermal insulation board and a preparation method thereof. Background technique [0002] Insulation materials are materials with a thermal coefficient less than or equal to 0.2. According to their materials, they are divided into three categories: inorganic insulation materials, organic insulation materials, and composite insulation materials. Traditional thermal insulation materials are mainly based on increasing the gas phase void ratio and reducing the thermal conductivity and conductivity; 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 the profile-type inorganic thermal insulation materials need to be assembled and constructed, there are defects such as many seams, damage to the appearance, poor waterproofness, and short service...

AI Technical Summary

Problems solved by technology

[0004] The thermal insulation board is a board made of thermal insulation materials, which is not only convenient for transportation, but also reduces the human factors in the construction, and the quality is greatly guaranteed. The thermal insulation board can meet the current energy-saving needs of building buildings. The preferred panel to improve the thermal insulation level of industrial and civil building exterior walls is also the first panel for energy-saving renovation of existing buildings; but there are problems such as poor thermal insulation, poor strength, and large application limitations.
