Description

Technical Field

[0001] This invention relates to the field of waterproof material construction technology, and more specifically to waterproof material adhesives and their application methods. Background Technology

[0002] Waterproofing materials are generally formed by the solidification of waterproof coatings. To bond waterproofing materials to a waterproof roof, the material is typically heated and melted before being applied. To achieve a good bond, a layer of waterproof adhesive is sometimes applied to the roof. Regarding waterproof adhesives, patent document CN105925214B, entitled "A Self-Adhesive Waterproof Adhesive," discloses a self-adhesive waterproof adhesive comprising: high molecular weight butyl rubber, medium molecular weight polyisobutylene, low molecular weight polyisobutylene, petroleum resin, ethylene vinyl acetate (EVA) elastomer, naphthenic oil, antioxidants, and ultraviolet absorbers. Such waterproof adhesives have good waterproofing effects, but they are not suitable for bonding waterproof materials to waterproof roofs. Patent document CN104277742B, entitled "A Waterproof Adhesive," also discloses a waterproof adhesive comprising powder and liquid. The powder includes cement, filler, mineral admixtures, high-efficiency water-reducing dispersant, water-repellent agent, crack-resistant fiber, and water-retaining agent; the liquid includes building 801 adhesive, defoamer, film-forming aid, polymer emulsion, and water. However, if applied to bonding waterproof materials to waterproof roofs, it still suffers from poor adhesion, requiring improvement. Summary of the Invention

[0003] The purpose of this invention is to address the above-mentioned shortcomings by providing a waterproof material adhesive that has good adhesion and is not prone to cracking, as well as its application method.

[0004] The technical solution of the waterproof material adhesive of the present invention is as follows: a waterproof material adhesive, comprising a first adhesive, a second adhesive and benzoic acid; The first adhesive is a mixture of the following components by weight: Anionic styrene-butadiene latex 30-50 parts, acrylic acid 20-30 parts, polyvinyl alcohol powder 10-15 parts, paste-like allyl polyoxyethylene ether 10-12 parts, foam plastic 8-10 parts, organic solvent 8-12 parts, cis-butadiene rubber powder 8-10 parts. The second adhesive is a mixture of the following components by weight: Acrylic acid 20-30 parts, methyl isobutylene 15-20 parts, powdered polyvinyl chloride resin 10-12 parts, methyltrimethoxysilane 10-12 parts, titanium dioxide 5-7 parts, boron nitride 5-7 parts, liquid epoxy resin 10-12 parts.

[0005] Furthermore, the first adhesive also contains 8-10 parts of dimethyl silicone oil.

[0006] Furthermore, the second adhesive also contains 8-10 parts of high molecular weight butyl rubber powder.

[0007] The technical solution of the present invention using the above-mentioned waterproof material adhesive is implemented as follows: A method for using the above-mentioned waterproof material adhesive, wherein, when using it, the first adhesive, the second adhesive, and benzoic acid are taken in a mass ratio of 9-10:9-10:0.3-0.5, the first adhesive and the second adhesive are mixed together and stirred to obtain a preliminary mixed adhesive, and benzoic acid is added to the preliminary mixed adhesive within 5 minutes and stirred again to obtain the waterproof material adhesive, the waterproof material adhesive is spread on the waterproof roof, the waterproof material is spread on the waterproof material adhesive, and the above-mentioned bonding of the waterproof roof and the waterproof material is completed within 2 hours.

[0008] Furthermore, during installation, the temperature of the waterproof roof is equal to the temperature of the adhesive used to bond the waterproof material.

[0009] To elaborate further, during installation, an organic solvent is first sprayed onto the waterproof roof.

[0010] Furthermore, during mixing, the temperature of the first adhesive is 45-50°C, and the temperature of the second adhesive is 30-35°C.

[0011] The beneficial effects of this invention are that the adhesive for waterproofing materials and its application method can make the laid waterproof coating bond more firmly to the construction surface, which is conducive to improving the construction quality. Detailed Implementation

[0012] The technical solution of the present invention will be further described below with reference to the embodiments.

[0013] It should be noted that the waterproof material described in this invention is formed by the solidification of a waterproof coating, such as modified asphalt. There may also be a base layer in the waterproof material.

[0014] The term "construction" refers to applying adhesive to the roof surface and then spreading waterproof material on top of the adhesive to create a waterproof roof.

[0015] The roof, for example, is a roof made of concrete.

[0016] Examples 1-4 The table below shows the statistics of various raw materials for each group (unit: grams). In the above embodiments, Example 1 involves mixing various raw materials together to obtain a first type of adhesive; When using, apply the first adhesive within 2 hours of its preparation to create the first waterproof roof. The first waterproof roof has some bonding effect, but the effect is not ideal, mainly because the waterproof material can be torn off the roof.

[0017] Examples 2, 3, and 4 involve mixing the first type of raw materials in each group to obtain a first adhesive, and mixing the second type of raw materials to obtain a second adhesive. In use, the first adhesive, the second adhesive, and benzoic acid are taken in a mass ratio of 9-10:9-10:0.3-0.5. The first and second adhesives are mixed together to obtain a preliminary mixture. Benzoic acid is added to the preliminary mixture within 5 minutes and stirred again to obtain the waterproof material adhesive. The bonding of the waterproof roof and the waterproof material is completed within 2 hours. This is the "construction" process, resulting in a second, third, and fourth waterproof roof. The second, third, and fourth waterproof roofs have a more ideal bonding effect than the first waterproof roof, mainly manifested in the fact that the waterproof material on the second, third, and fourth waterproof roofs is less likely to be torn off.

[0018] In conclusion, preparing each set of raw materials separately and mixing them within 2 hours before use can achieve a stronger bond between the waterproofing material and the waterproof roof.

[0019] Example 5 Based on Examples 2-4 above, the first raw material further contains 8-10 parts of dimethyl silicone oil, resulting in a fifth adhesive. Using this fifth adhesive, a fifth waterproof roof is obtained. Compared to the second, third, and fourth waterproof roofs, the fifth adhesive exhibits greater bonding strength in terms of adhesion.

[0020] Example 6 Based on Examples 2-5 above, the second adhesive further contains 8-10 parts of high molecular weight butyl rubber powder, resulting in a sixth adhesive. Using the sixth adhesive, a sixth waterproof roof is obtained. Compared to the second, third, fourth, and fifth waterproof roofs, the sixth waterproof roof exhibits a longer aging resistance time in terms of bonding performance.

[0021] Example 7A Based on the above embodiments 2-6, during the installation, the temperature of the waterproof roof is 10°C higher or lower than the temperature of the waterproof material adhesive, resulting in the seventh A waterproof roof.

[0022] Example 7B Based on the above embodiments 2-6, during the installation, the temperature of the waterproof roof is equal to the temperature of the waterproof material adhesive, resulting in the seventh B waterproof roof.

[0023] The adhesion between the waterproofing material and the waterproofing roof in the 7A waterproofing roof is less than that between the waterproofing material and the waterproofing roof in the 7B waterproofing roof.

[0024] Example 8A Based on the above embodiments 2-6, during the laying process, the waterproof material adhesive is directly spread on the waterproof roof, and then the waterproof material is spread on the waterproof material adhesive, up to the eighth A waterproof roof.

[0025] Example 8B Based on Examples 2-6 above, an organic solvent is first sprayed onto the waterproof roof surface. Then, a waterproof material adhesive is spread on the waterproof roof surface. Finally, the waterproof material is spread on top of the waterproof material adhesive, resulting in the eighth B waterproof roof. The organic solvent mentioned is, for example, kerosene or glycerin. The adhesion between the waterproofing material and the waterproofing roof of the eighth A waterproofing roof is less than that between the waterproofing material and the waterproofing roof of the eighth B waterproofing roof.

[0026] Example 9 Based on Examples 2-6 above, during mixing, the temperature of the first adhesive is 45-50°C, and the temperature of the second adhesive is 30-35°C. A ninth adhesive is obtained, and a ninth waterproof roof is constructed using this ninth adhesive.

[0027] The adhesion between the waterproofing material and the waterproofing roof is stronger in the ninth type of waterproof roof.

[0028] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
