[0042] Preparation of self-made antibacterial waterproof filler:

[0043](1) Mix lemon, hawthorn and water according to the mass ratio of 5:3:2, put them into a pulverizer, pulverize for 30-40 minutes to obtain a mixture, put the obtained mixture into a fermenter, and place the fermenter open In a moldy room with a temperature of 40-50°C and a relative air humidity of 65-75%, let it stand for 10-12 days to mold;

[0044] (2) After the above-mentioned mold is over, seal the mouth of the fermenter, and continue to seal and ferment at a temperature of 28-32°C for 3-5 days. After the fermentation is over, the fermentation product is obtained. After the fermentation, the filter residue is filtered and separated to obtain the fermentation filtrate ;

[0045] (3) Weigh the zeolite and grind it through a 100-mesh sieve, collect the sieved powder, mix the sieved powder with the fermentation filtrate and potassium rhodanide at a mass ratio of 5:2:1, and then move it into a high-tempera...

Abstract

The invention relates to an anti-cracking antibacterial waterproof ceiling plate and a preparation method thereof, and belongs to the technical field of decorative material preparation. The preparation method comprises the following steps: crushing lemon, hawthorn and water, rancidifying and mildewing in a high-temperature and high-humidity environment, carrying out sealed fermentation on the rancidified and mildewed product to obtain a fermentation filtrate rich in organic carboxylic acid, acting on zeolite powder by using organic acid in the fermentation filtrate, and modifying by using silver nitrate to prepare a self-made antibacterial waterproof filler; the carrying out high temperature high pressure boiling to obtain modified fiber, and at last compounding the self-made antibacterialwaterproof filler, organic silane, and gypsum powder to obtain the anti-cracking antibacterial waterproof ceiling plate which is relatively low in water absorption thickness expansion rate, excellentin waterproof performance, relatively high in antibacterial rate and obvious in antibacterial effect. Meanwhile, the ceiling plate is good in mechanical property, not prone to deformation, long in service life and wide in application prospect.

Description

technical field [0001] The invention relates to a crack-resistant, antibacterial and waterproof ceiling board and a preparation method thereof, belonging to the technical field of preparation of decorative materials. Background technique [0002] Ceiling boards are widely used in home decoration and commercial decoration. At present, there are more and more types of ceiling boards on the market. With the continuous improvement of people's requirements for environmental quality after decoration, they have the advantages of beautifying the environment, safety and reliability, and are beneficial Healthy building materials are becoming more and more popular. [0003] Domestic outfit condole is the common link in domestic outfit. The suspended ceiling is classified differently according to the material of the decorative board. Ceiling decoration materials are the main basis for distinguishing the name of the ceiling, mainly including: light steel keel gypsum board ceiling, gyps...
