Problems solved by technology

[0004] Publication number is that the Chinese patent document of CN104277544A discloses a kind of diatom mud wall paste, and this diatom mud wall paste comprises diatomite, ash calcium powder, hydroxypropyl methylcellulose, redispersible latex powder, water-based Styrene-acrylic emulsion and water, but 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 It is easy to release VOC substances such as formaldehyde, and cannot be truly green and environmentally friendly
[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 generally have low strength, poor water retention, easy powder removal, poor stretchability, and easy cracking, which seriously affects the performance of diatom mud.

Abstract

The invention discloses a nylon-fiber-reinforced anti-impact diatom ooze material and a preparation method thereof. The nylon-fiber-reinforced anti-impact diatom ooze material includes, by mass, 15-35 parts of diatomite, 20-40 parts of heavy calcium carbonate, 8-20 parts of ash calcium powder, 8-20 parts of quartz sand, 2-5 parts of nano titanium dioxide, 1-4 parts of negative ion powder, 0.5-2.5 parts of cellulose ether, 0.1-0.5 parts of pre-gelatinized starch, and 0.1-2 parts of nylon fibers. The nylon-fiber-reinforced anti-impact diatom ooze material is prepared by mixing the diatomite with nylon fibers and multiple materials, so that the diatom ooze material has strong adhesion strength and excellent anti-impact property, is excellent in hot and cold shrinkage performance and has good air purifying performance. The promotion and application prospects of the nylon-fiber-reinforced anti-impact diatom ooze material are greatly improved.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a nylon fiber-reinforced impact-resistant diatom mud material and a preparation method thereof. Background technique [0002] Nowadays, while people are beautifying their living room, they also pay great attention to environmental protection, so diatom mud is more and more favored by consumers at home and abroad. Because it does not contain harmful chemical substances, in addition to the characteristics of non-combustibility, sound insulation, waterproof, light weight and heat insulation, it also has the functions of dehumidification, deodorization, and indoor air purification. It is an excellent environmental protection natural material for indoor and outdoor decoration. [0003] Japan is the first country to develop diatom mud as a decorative wall material for building interior walls. The Japanese patent document with publication number JP2008241251A discloses that a...
