Problems solved by technology

[0009] The purpose of the present invention is to solve the above-mentioned problems, such as water-emulsion coatings have low solid content, limited drying speed and affect construction efficiency, and cannot be used at low temperatures, and are generally not suitable for construction below 5°C; a large amount of solvent oil, toluene, Benzene aromatic compounds such as xylene lead to a large amount of volatile gas in polyurethane waterproof coatings, which are highly toxic and pollute the environment; solvent-free polyurethane coatings have many problems such as drying speed.

preparation example Construction

[0064] In the embodiment of the present invention, the preparation method of the solvent-free fast curing reactive waterproof coating comprises:

[0065] (1) Add alkoxy silicon-based modified polyether polymer resin, heavy powder, optional light powder, plasticizer and dispersion stabilizer to the reactor, first adjust the speed of the high-speed disperser to 1000rpm, After 5 minutes, adjust the speed of the high-speed disperser to 1750rpm, and disperse at a high speed for 40 minutes at this speed;

[0066] (2) Add dehydrating agent, coupling agent, and optional thixotropic agent, adjust the speed of the high-speed disperser to 1000rpm, keep stirring under vacuum conditions for 50min, and check the water content until the water content is ≤1200ppm;

[0067] (3) Add the catalyst under normal pressure, then stir at room temperature under vacuum for 30 minutes, turn off the agitator and the vacuum pump to obtain a solvent-free fast curing reaction type waterproof coating.

Abstract

The invention discloses a solvent-free quick-curing reaction type waterproof coating and a preparation method thereof as well as a roll-coating laminated waterproof construction system and a construction method thereof. The solvent-free quick-curing reaction type waterproof coating comprises the following raw materials in parts by weight: 80-120 parts of alkoxy silicon-based modified polyether polymer resin, 20-40 parts of a dispersion stabilizer, 260-320 parts of heavy powder, 70-100 parts of a plasticizer, 3-5 parts of a dehydrating agent, 3-5 parts of a silane coupling agent and 2-4 parts of an organic tin catalyst. The coating can be used for construction at a low temperature (-20 to 5 DEG C), has the solid content of more than or equal to 99%, can meet the construction thickness requirement (thickness of 1.5-2.0 mm) at one time, has the characteristics of high bonding strength, high curing and film-forming speed at a low temperature and the like, greatly improves the constructionefficiency and solves the problems in winter construction.

Description

technical field [0001] The invention belongs to the field of architectural coating materials, and more specifically relates to a solvent-free fast-curing reaction type waterproof coating and a preparation method thereof, a coil-coated laminated waterproof construction system and a construction method thereof. Background technique [0002] Waterproof coatings can work in construction environments with complex shapes, and can form a seamless continuous waterproof film layer with remarkable waterproof effect. It is suitable for various waterproof engineering systems such as roofs, basements, bridges, and pools. [0003] Polyurethane waterproof coatings are widely used in the field of building waterproofing due to their excellent mechanical properties, good low-temperature flexibility, and excellent chemical corrosion resistance. However, many products currently on the market add a large amount of solvent oil, toluene, xylene and other benzene aromatic compounds, resulting in a ...
