Problems solved by technology

[0004] There are many enterprises producing waterproof coatings in our country, and there are many kinds of coatings, but they are all common products. The existing waterproof coatings, the reactive type is too expensive, which limits the scope of use, and the solvent-based and water-emulsion waterproof coatings have low solid content. The thin film formed by one-time brushing affects the construction progress and is far from meeting the waterproof requirements of construction projects in my country. Therefore, it is of great significance to develop a high-tech waterproof coating product with excellent performance and is imminent.

Embodiment Construction

[0015] (1) Preparation of styrene-acrylic emulsion

[0016] The monomer is pre-emulsified with surfactant and water in the amount designed according to the formula, and then pumped into the high-level tank, and the initiator is dissolved in water and then pumped into another high-level tank; the above two are added dropwise into the reactor for polymerization Reaction, the reaction temperature is controlled at 70-85 ° C, and the addition rate is controlled at the same time, so that the reaction material is dripped in 3-3.5 hours, and finally kept for 1-1.5 hours to make the reaction complete, then cooled, and the pH value of the emulsion is adjusted with ammonia water to 7-8.

[0017] (2) Preparation of cement waterproof coating

[0018] Add 1% dispersant, 0.6% film forming agent, 4% defoamer, 200% calcium carbonate, 20% dibutyl phthalate to the styrene-acrylic waterproof emulsion prepared above in the reaction kettle. While stirring, heat up to 65°C, stir for 1 hour, discha...

Abstract

The invention relates to a solvent-type cement impermeable and waterproof coating which is mainly composed of a styrene-acrylic water-proof emulsion, a dispersant, a film forming agentm, an antifoaming agent, calcium carbonate and o-benzene dimethyl dibutyl. The solvent-type cement impermeable and waterproof paint is stable in structure, and the coating of the paint is good in hydrophobic effect, good in airtightness, resistant to water and leakage, quick in construction speed and good in usage effect.

Description

technical field [0001] The invention relates to a solvent-based cement anti-seepage and waterproof coating, which belongs to the field of surface protection. Background technique [0002] In recent years, due to the lagging of construction technology and waterproof coating products for building walls and decorative materials, there are many phenomena of water leakage on the outer walls. etc. to make a high-performance anti-leakage and anti-seepage waterproof coating. The most prominent advantage of this type of coating is that it will not discharge substances that pollute the environment during production, construction and application, and it meets environmental protection requirements. [0003] In addition, the development of multifunctional waterproof coatings is also a must for coating manufacturers. It is reported that during the "Ninth Five-Year Plan" period, my country focused on the development of polyurethane waterproof coatings, polymer emulsion cement waterproof ...
