Heat preservation decoration plate and manufacturing method thereof

Abstract

The invention discloses a heat preservation decoration plate and a manufacturing method thereof. The heat preservation decoration plate comprises a heat preservation layer and a decoration layer arranged on one outer side surface of the heat preservation layer, wherein the heat preservation layer and the decoration layer are integrally formed; the heat preservation layer comprises the following raw materials in parts by weight: 40-50 parts of sepiolite powder, 10-15 parts of crushed crude pearlite, 30-40 parts of glass powder, 5-10 parts of bentonite, 2-3 parts of calcium carbonate, 0.1-1 part of charcoal, 2-3 parts of sodium phosphate, 2-3 parts of silicon carbide, 2-3 parts of borax and 25-35 parts of water. According to the technology that the decoration layer and the heat preservation layer are integrally pressed into a blank and then the blank is burnt, the decoration layer and the heat preservation layer are integrally combined, so that the two layers are firmly connected, and the heat preservation decoration plate has heat preservation and heat isolation functions and also achieves an effect of decorating an external wall; furthermore, raw materials selected for the heat preservation layer and the decoration layer are matched, so that the heat preservation decoration plate is light in mass and better in fireproofing and heat preservation and isolation effect.

Description

technical field [0001] The invention relates to the field of building material design, in particular to a thermal insulation decorative board and a manufacturing method thereof. Background technique [0002] Building energy conservation is the main content of implementing the national environmental protection and energy conservation policies, and is an important part of implementing the sustainable development of the national economy. my country attaches great importance to building energy conservation. Under the guidance of a series of national energy conservation policies, regulations, standards and mandatory provisions, the energy conservation work in residential construction in my country has been continuously deepened, energy conservation standards have been continuously improved, and it is mandatory that the energy conservation rate of buildings should not be lower than 50%, and relevant data show that the energy loss caused by wall heat transfer is about 1 / 3 of the tot...
