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...
