Abstract

The invention discloses a preparation method of a fireproof plate composite material. The preparation method comprises the following steps: slowly adding organic titanium alkoxide, inorganic zircon salt, and inorganic magnesium salt into sulfuric acid with a certain concentration in sequence under stirring; stirring to carry out hydrolysis and polymerization to obtain a solution (A); under a water bath condition, adding a surfactant (sodium lignin sulfonate) and a dispersant (glucose) into a certain amount of water, and stirring to obtain a solution (B); pouring the solution (A) into the solution (B), allowing the system to stand still for a while to carry out aging; adjusting the pH value to the neutral area to obtain a composite solution (C); adding calcium silicate into a certain amount of water, adding polypropylene fibers and starch under stirring, then slowly pouring the solution into the solution (C), adding a little amount of cement, stirring for a while, and removing the upper layer of solution through suction filtration to obtain wet filter residues namely the fireproof plate composite material. The fireproof plate composite material can be transferred to a template, then the template is placed in a reactor, and a fireproof plate is obtained through the following steps: controlling the pressure, heating the steam, maintaining the temperature and pressure, carrying out steam maintenance, and demoulding.

Description

technical field [0001] The invention belongs to the preparation technology of fireproof building materials, in particular to a preparation method of a fireproof board composite material. Background technique [0002] Fireproof board is a kind of refractory building material for surface decoration. It is widely used in many fields such as interior decoration, furniture, kitchen cabinets, and exterior walls. It plays an important role especially in public places, such as office buildings and stations. [0003] The early fireproof boards were made by impregnating base paper (such as kraft paper) with melamine and phenolic resin under high temperature and high pressure. These boards usually have high surface hardness, wear resistance, high temperature resistance, impact resistance and other properties, but their fireproof performance is not very ideal. . In recent years, more and more attention has been paid to silicate fiber boards, glass magnesium boards, etc. CN103011725A re...
