Problems solved by technology

[0004] However, the polymer self-adhesive film waterproof membrane only relies on the polymer self-adhesive adhesive to bond with the synthetic polymer sheet, and the polymer self-adhesive film usually It is very thin, and the polymer self-adhesive adhesive is usually composed of hot-melt adhesive. The cohesive force of this type of adhesive is large, resulting in most water-based coatings such as polymer self-adhesive film waterproof membranes and polyurethane coatings, asphalt membranes or other polymers. Poor adhesion of waterproof membrane
Therefore, the polymer self-adhesive film waterproof membrane can only be used alone and cannot be used in combination with other waterproof products.
According to the existing waterproof construction standard requirements, the polymer self-adhesive film waterproof membrane can only achieve the second-level waterproof effect when used alone, and cannot achieve the first-level waterproof effect
Therefore, the polymer self-adhesive film waterproofing membrane cannot be used in important buildings and high-rise buildings, which limits its scope of use.

Embodiment 1

[0050] This example provides a water-based non-asphalt-based waterproof coating, and its raw material composition is shown in Table 1, and the preparation method is as follows:

[0051] Dissolve anionic emulsifier, nonionic emulsifier and stabilizer in water to prepare soap solution, and heat to 50°C for later use; mix C5 petroleum resin and aromatic hydrocarbon oil and heat to 120°C, stir evenly to obtain sizing material; sizing material and soap At the same time, a colloid mill is used to prepare an emulsified rubber compound with stable performance; the defoaming agent, bactericidal preservative, anionic SBS latex, anionic SBR latex and the emulsified rubber compound are mixed, stirred evenly, and the thickener is slowly added to reach the set viscosity. 13000mPa . s, to obtain a water-based non-asphalt-based waterproof coating.

Embodiment 2

[0053] This example provides a water-based non-asphalt-based waterproof coating, the preparation process of which is the same as that of Example 1, the difference is only in that the composition of its raw materials is different from that of Example 1, and its specific composition is shown in Table 1.

Embodiment 3

[0055] This example provides a water-based non-asphalt-based waterproof coating, the preparation process of which is the same as that of Example 1, the difference is only in that the composition of its raw materials is different from that of Example 1, and its specific composition is shown in Table 1.

Abstract

The invention relates to a water-based non-asphalt-based waterproof coating, a preparation method thereof and a waterproof laminate. The water-based non-asphalt-based waterproof coating comprises the following components: tackifying resin, softening oil, polymer latex, an anionic emulsifier and water, the mass ratio of the tackifying resin to the softening oil to the polymer latex is (30-50): (10-25): (5-20), and the polymer latex is selected from one or a combination of two of SBS latex and SBR latex. The waterproof laminate includes a waterproof coating formed from an aqueous non-asphaltic based waterproof coating. The waterproof coating has high peel strength with a polymer self-adhesive film waterproof roll, has excellent extensibility and high and low temperature resistance, and can be applied to waterproofing of high-rise buildings and important buildings.

Description

technical field [0001] The invention relates to a water-based non-asphalt-based waterproof coating, a preparation method thereof, and a waterproof laminate. Background technique [0002] Waterproofing membranes are usually used in the field of building waterproofing. The existing waterproofing membranes usually include asphalt-based waterproofing membranes and polymer waterproofing membranes, and polymer self-adhesive membrane waterproofing membranes are an important type of polymer waterproofing membrane. material. [0003] The polymer self-adhesive film waterproofing membrane is a polymer waterproofing membrane composed of synthetic polymer sheet, polymer self-adhesive and surface isolation film. The construction method can be dry or wet. This kind of waterproof membrane can achieve excellent waterproof effect, and has excellent physical properties, aging resistance and weather resistance, so it has become one of the important materials in the field of building waterproof...
