Problems solved by technology

However, general water-based waterproof coatings have disadvantages such as single function, thin coating, not dense enough, poor adhesion to the substrate, no impact resistance, no puncture resistance, etc. Usually, after the waterproof layer is completed, another layer is required The protective layer not only prolongs the construction period, but also increases the project cost

no. 1 example

[0024] The water-based thick rubber-plastic waterproof mortar and the preparation method thereof comprise the following materials in parts by weight: 33-65 parts of polymer emulsion, 2.5-6.5 parts of tackifying resin, 0.3-1.5 parts of high-strength reinforcing fiber, and 0.3-1.5 parts of waste rubber powder. 20-35, filler 3-22, additive 1.7-5.7 and water 2.5-7.5. The filler is heavy calcium carbonate, or talcum powder, or plasticizer, or bentonite; the auxiliary agents include preservatives, water-retaining agents, cross-linking agents and / or coupling agents.

[0025] Set the cement mortar mixer at the low speed gear, install the mixing tank, and adjust the mixing paddle as close to the bottom of the tank as possible. Weigh 54kg of polymer emulsion, add 4kg of tackifying resin into the mixing tank, and start the mixer; in the stirring state, weigh 0.9kg of cross-linking agent and 0.1kg of water-retaining agent and put them in the cement mortar mixer; after fully stirring for 1...

[0028] Taking by weighing polymer emulsion is 58kg respectively, and water-based tackifying resin is 4.3kg, and crosslinking agent is 1kg, and water retaining agent is 0.1kg, and mesh bentonite is 3.2kg, and waste rubber powder is 27.4kg, and mesh bicarbonate is 3.9kg and 2.1kg of water. Others are not described with the first embodiment.

no. 3 example

[0030] Taking by weighing high molecular emulsion is 60kg respectively, and water-based tackifying resin is 4.5kg, and crosslinking agent is 1.2kg, and water retaining agent is 0.1kg, and mesh bentonite is 3.4kg, and waste rubber powder is 24.8kg, and mesh bicarbonate is 4kg and 2kg of water. Others are not described with the first embodiment.

[0031] How to use water-based thick rubber and plastic waterproof mortar and precautions:

[0032] 1) Base surface treatment:

[0033] If the concrete base surface is relatively flat and solid, free from oil stains, clear water, slightly moist, and the temperature is between +5-40°C, it can be directly constructed (it is not suitable for construction in rainy and snowy days).

[0034] If the concrete base surface is very dry, you need to sprinkle a little water to moisten it before construction.

[0035] If the concrete base surface is relatively loose and not solid, it must be treated with primer first. The primer solution is: poly...

Abstract

The invention provides waterborne thick rubber-plastic waterproof mortar and a method for preparing the same. The formula of the mortar comprises the following components in part by weight: 33 to 65 parts of macromolecular emulsion, 2.5 to 6.5 parts of tackifying resin, 0.3 to 1.5 parts of high-strength reinforcement fiber, 20 to 35 parts of waste rubber powder, 3 to 22 parts of filling materials, 1.7 to 5.7 parts of assistant and 2.5 to 7.5 percent of water, wherein the macromolecular emulsion is emulsion of polystyrene-acrylic ester and mainly used as a film forming of the waterborne thick rubber-plastic waterproof mortar; and the filling material is heavy calcium carbonate, talcpowder, plasticizer or bentonite. The waterborne thick rubber-plastic waterproof mortar of the invention can replace part of the waterproof coiled material and meet the application thickness requirement after one-time coating, and has the characteristics of high elasticity, impact resistance and backfill puncture resistance; the mortar can be used for water resistance on the upstream face as well as downstream face, and no other protective layer is added; the mortar is the multi-functional building mortar having the advantages of heat insulation and heat absorption and noise reduction and noise elimination; and in the formula, a large amount of waste tire rubber powder is used, so that the method for preparing the mortar makes an active contribution to environmental protection and resource recovery.

Description

technical field [0001] The invention relates to the field of building waterproof materials, in particular to a water-based thick rubber-plastic waterproof mortar and a manufacturing method thereof, which belongs to the innovative technology of waterproof coatings. Background technique [0002] At present, waterproof coating is an important building material. With the construction of transportation facilities such as highways, railways, subways, and light rails in my country, and the rapid development of the real estate industry, its demand is increasing rapidly. In addition, as the national environmental protection laws and regulations become more and more stringent, people pay more and more attention to environmental protection, and the development of the coatings industry is also moving towards pollution-free, pollution-free, resource-saving, energy-saving, and low organic volatiles (VOC). Goal follow-up, it is an inevitable trend in the development of coatings to graduall...
