Abstract

The invention relates to a perlite calcium silicate board and a preparation method thereof. The method comprises the following steps: (1) preparing materials, namely weighing expanded perlite calcium silicate, cellulose, quartz sand, cement and tourmaline as raw materials according to volume percentage; (2) stirring materials, namely mixing and uniformly stirring the raw materials by virtue of a stirrer; (3) molding, namely injecting the uniformly stirred materials into a belt by virtue of a high-pressure pump, and pressing and molding by adopting a belt flow slurry conveying roller; (4) baking, namely maintaining the molded product at normal temperature for 4 hours, carrying out vapor-pressing for 18 hours at 100 DEG C, and finally baking at 120 DEG C for 5 hours. Compared with the prior art, the perlite calcium silicate board has the advantages of negative oxygen ion release, environmental friendliness, strong practicality and the like.

Description

technical field [0001] The invention relates to a composite board for building, in particular to a perlite calcium silicate board. Background technique [0002] Expanded perlite is a kind of white granular material with a honeycomb structure inside, which is made of perlite ore after preheating and instantaneous high-temperature roasting and expansion. The principle is: perlite ore is crushed to form ore with a certain particle size, preheated and roasted, heated rapidly (above 1000°C), the water in the ore is vaporized, and expands inside the softened glassy ore to form a porous structure and volume expansion 10-30 times non-metallic mineral products. Perlite is divided into three forms according to its expansion technology and use: open cell, closed cell, and balloon. [0003] However, the expanded perlite insulation board is made of expanded perlite particles bonded into a plate shape through an adhesive. Although it is light in weight, the production process is complica...
