Perlite heat preservation board and preparation method thereof

Abstract

The invention discloses a perlite heat preservation board and a preparation method thereof. The heat preservation board comprises the following raw materials: modified expanded perlite, kaolin, cement, plant ash, diatomaceous earth, sodium trimethylsilanolate, epoxy chloropropane, divinyl benzene, ethyl orthosilicate, N,N'-methylene bisacrylamide, calcium sulphate, sodium chloroacetate, sodium chloride, sodium silicate and water; and the preparation method includes the following steps: uniformly mixing the modified expanded perlite, the kaolin, the cement, the plant ash and the diatomaceous earth to obtain a mixture A; uniformly mixing the remaining raw materials, adding water, and performing stirring to obtain a solution B; and adding the solution B into the mixture A, performing uniformstirring, pouring the stirred solution into a mold, performing compression moulding to obtain a perlite heat preservation board blank body, performing primary drying, performing secondary drying, andperforming tertiary drying to obtain the perlite heat preservation board. The perlite heat preservation board provided by the invention has good heat preservation performance, high compressive strength, is not easy to damage, and has high durability.

Description

technical field [0001] The invention relates to the field of thermal insulation board processing, in particular to a perlite thermal insulation board and a preparation method thereof. Background technique [0002] In today's society, developed countries have paid unprecedented attention to energy conservation. my country's current heating energy consumption per unit building area is equivalent to 3-4 times that of developed countries with similar climate conditions. China is a country that is relatively scarce in energy, so it is reasonable to use energy. Improving energy utilization rate is the fundamental plan of social development in our country, and the improvement of energy-saving technology of building exterior wall enclosure structure and the renewal of thermal insulation materials are of great significance to the reduction of social and building energy consumption. [0003] The wall insulation and energy-saving materials used in my country's construction market are ma...
