Problems solved by technology

However, the redispersible rubber powder used in this patent belongs to organic latex powder. Although it can make the bonding stronger, it is easy to block the micropores and lose the breathing and filtering effect of diatom mud. In addition, the materials used are easy to release VOC substances such as formaldehyde. , unable to be truly green
[0005] The Chinese patent literature with the publication number CN101700965A discloses a kind of environment-friendly diatom mud wall material powder, wall material and preparation method thereof, the wall material mainly adopts inorganic materials such as diatomite, kaolin, sepiolite, vermiculite powder, etc. The effect of heat preservation and adsorption purification is better, but the adhesion performance of inorganic materials is poor, and it is easy to drop powder and fall off
[0006] In the prior art, the inorganic adhesives used in diatom mud are generally low in strength, poor in water retention, easy to remove powder, and cannot be used alone; and the disadvantages of wood fiber species are single, easy to absorb water and corrode, and the reinforcement effect is not high enough, which seriously affects the quality of diatom mud. performance

Abstract

The invention discloses a polyester fiber reinforced anti-cracking diatom ooze material, and a preparation method thereof. The polyester fiber reinforced anti-cracking diatom ooze material comprises, by mass, 15 to 35 parts of diatomite, 20 to 40 parts of heavy calcium carbonate, 8 to 20 parts of ash calcium powder, 8 to 20 parts of quartz sand, 2 to 5 parts of nanometer titanium dioxide, 1 to 4 parts of tourmaline, 0.5 to 2.5 parts of cellulose ether, 0.1 to 0.5 part of pregelatinized starch, and 0.1 to 2 parts of polyester fiber. According to the preparation method, diatomite, heavy calcium carbonate, ash calcium powder, quartz sand, nanometer titanium dioxide, tourmaline, and polyester fiber are taken as the raw materials, nontoxic and renewable adhesives cellulose ether and pregelatinized starch are also added, so that the obtained polyester fiber reinforced anti-cracking diatom ooze material possesses excellent cracking resistance and anti-pulverization ability; the preparation method is safe, and is friendly to the environment; production cost is low; and large-scale production can be realized easily.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a polyester fiber reinforced crack-resistant diatom mud material and a preparation method thereof. Background technique [0002] Diatom mud is a natural environmental protection interior wall decoration material, which is used to replace wallpaper and latex paint, and plays the role of interior wall decoration and indoor air purification. Its main raw materials are diatomite and amorphous silica. Since the surface of diatomite is rich in fine pores and a small amount of mesopores and micropores in the interior, it has a unique multi-level channel structure. The specific surface area of ​​diatomite can reach 65m 2 / g, light and non-toxic, powder bulk density is only 0.34-0.65g / m 3 , so it has strong adsorption, and can be used as filter aid, adsorption, thermal insulation and catalytic carrier materials, etc.; because its main component is amorphous silica (SiO 2 .nH...
