Sand fixing agent and preparation method and application thereof

Abstract

The invention discloses a sand fixing agent as well as a preparation method and an application thereof, and belongs to the technical field of building materials. The sand fixing agent comprises a component A and a component B, the component A comprises the following substances: a styrene-acrylate polymer, polyvinyl alcohol-epoxy resin, sodium alginate and zinc stearate; the component B is preparedfrom the following substances: butyl stearate, 5-chloro-2-methyl-3 (2H) isothiazolone and 2-methyl-3 (2H) isothiazolone; and deionized water; and stirring in an emulsifying pot, uniformly mixing, heating, preserving heat, cooling, detecting and sub-packaging to obtain a finished product. The sand fixing agent has excellent waterproof, mildew-proof, anti-seismic and curing effects, is safe in component and convenient to use, and can be applied to roof waterproofing, sand fixing, dust fixing, outer wall sand fixing, waterproofing, wall damp proofing, alkali resistance, mildew proofing, back water pressure waterproofing and underground engineering sealing damp proofing, so that multiple purposes of the sand fixing agent are achieved, and the sand fixing agent is multipurpose, convenient to use and high in practicability. Improving construction efficiency.

Problems solved by technology

[0002] Nowadays, exterior wall and interior wall coatings are mostly decorated with exterior wall coatings, but after a period of time after the existing building exterior wall coatings are painted, problems such as peeling, bursting, and falling off are prone to occur, which not only affects the walls and exteriors. The beauty of the wall, but also reduces the strength of the wall and the outer wall

Moreover, the exterior wall paints on the market have many steps to use, time-consuming and labor-intensive, the construction cost is relatively high, and they are not durable.

[0003] Existing architectural decorative coatings only play a basic role in modifying the wall surface, and cannot reinforce the sand particles on the surface of the external wall, causing the wall to be easily eroded, cracked, without curing effect, and the shockproof effect is also very poor. Will fall off, reducing the service life of decorative coatings

[0004] In addition, the existing exterior and interior wall coatings are not waterproof, and are prone to water seepage. After a long time of use, the walls and even the walls where the water seeps are prone to mold and bacteria growth, which in turn reduces the quality and service life of the walls, and is not conducive to living human health

Moreover, the exterior wall paints on the market contain a large amount of formaldehyde, which is not conducive to the health of the home and is not environmentally friendly.

[0005] There are also a variety of decorative coatings, all of which correspond to different functions one by one. The functions of waterproofing, sand-fixing, decoration and mildew resistance are not combined in the same spraying material, resulting in many walls, exterior walls, pressured waterproofing, etc. They all correspond to different decorative paints, and they must be carefully distinguished when used. It is very cumbersome to use, time-consuming and labor-intensive, and the effect is not good.
