Problems solved by technology

[0002] Most of the existing waterproof coatings are polyurethane or epoxy resins. This type of waterproof coating needs to be cured. After curing, the flexibility becomes poor, the low temperature resistance is poor, and it is easy to crack at low temperature. There are cracks at minus 10°C, so it is not easy to apply at low temperature; Poor heat resistance, easy to flow at high temperature
Therefore, existing waterproof coatings have defects such as not being able to deal with building deformation joints and displacement joints.

Embodiment 1

[0016] Example 1: Non-cured rubber asphalt waterproof coating

[0017] (one) The composition is as follows:

[0018] Asphalt 60%, rubber 10%, dispersant 5%, tackifier 5%, filler 20%;

[0019] The rubber is styrene-butadiene rubber;

[0020] The dispersant is naphthenic oil;

[0021] The tackifier is rosin resin;

[0022] The filler is bentonite.

[0023] (2) The preparation method is as follows:

[0024] 1) Take the material according to the above-mentioned raw material ratio, and heat the asphalt to 140℃-160℃;

[0025] 2) Add dispersant and tackifier to asphalt and stir for about 30 minutes;

[0026] 3) Add rubber and shear for 1-2 hours until the dispersion is uniform;

[0027] 4) Add filler, stir evenly, and discharge. The results are shown in Table 1.

Embodiment 2

[0028] Example 2: Non-cured rubber asphalt waterproof coating

[0029] (one) The composition is as follows:

[0030] Asphalt 51%, rubber 22%, dispersant 12%, tackifier 9%, filler 6%;

[0031] The rubber is styrene-butadiene rubber;

[0032] The dispersant is furfural oil;

[0033] The tackifier is APOP;

[0034] The filler is light calcium carbonate.

[0035] (2) The preparation method is as follows: with Example 1. The results are shown in Table 1.

Embodiment 3

[0036] Example 3: Non-curing Rubber Asphalt Waterproof Coating

[0037] (one) The composition is as follows:

[0038] Asphalt 45%, rubber 25%, dispersant 15%, tackifier 10%, filler 5%;

[0039] The rubber is styrene-butadiene rubber;

[0040] The dispersant is a mixture of reduced second-line oil and naphthenic oil in a volume ratio of 1:1;

[0041] The tackifier is hard asphalt;

[0042] The filler is a mixture of light calcium carbonate and bentonite in a weight ratio of 1:1.

Abstract

The invention relates to a non-curing rubber asphalt waterproof paint. The technical proposal adopted is that: the non-curing rubber asphalt waterproof paint comprises the following raw materials by weight: 45%-60% of asphalt, 10%-25% of rubber, 5%-15% of a dispersing agent, 5%-10% of a tackifier and 5%-20% of filler. The preparation method is as follows: proportionally taking the raw materials, heating the asphalt to 140-160DEG C; adding the dispersing agent and the tackifier to the asphalt, stirring for about 30 minutes; adding the rubber for mixing; adding the filler, mixing evenly, and discharging. The non-curing rubber asphalt waterproof paint does not cure, and is low temperature resistant, does not flow at high temperature, and good in waterproof performance.

Description

technical field [0001] The invention belongs to the field of coatings, in particular to a non-curing rubber asphalt waterproof coating. Background technique [0002] Most of the existing waterproof coatings are polyurethane or epoxy resins. This type of waterproof coating needs to be cured. After curing, the flexibility becomes poor, the low temperature resistance is poor, and it is easy to crack at low temperature. There are cracks at minus 10°C, so it is not easy to apply at low temperature; Poor heat resistance, high temperature prone to flow. Therefore, the existing waterproof coatings cannot deal with defects such as building deformation joints and displacement joints. Contents of the invention [0003] The purpose of the present invention is to provide a non-curing rubber asphalt waterproof coating which is non-curing, low temperature resistant, high temperature non-dripping, and good waterproof performance. [0004] The technical scheme adopted in the present inve...
