Problems solved by technology

[0003] 1. Oily products contain toxic substances harmful to the human body (solvents used as diluents, such as toluene), which will damage the environment and human health
In addition, the adhesive layer of oil-based (solvent-based) products is very hard. If it is slightly bent, the adhesive layer will crack, lack elasticity, and have poor sound insulation effect
[0004] 2. Water-soluble anti-rust glue is poisonous, strong adhesion, easy to pollute the environment, and the sound insulation effect is remarkable, but the construction is greatly affected by temperature and humidity, and takes a long time
[0005] 3. Composite polymer resin paint, quick-drying, with high water resistance, high elasticity, high corrosion resistance, high sound absorption and noise reduction, but after a period of time, the adhesive layer will become very hard and the performance will decline

Embodiment 1

[0018] At 25°C, add 1 kg of monoglyceride stearate and 5 kg of diethanolamide to 6 kg of natural rubber, stir for 30 minutes, then add 2 kg of paraffin oil, 1 kg of polyisobutylene and 5 kg of bentonite, and stir for another 30 minutes to obtain synthetic rubber. Continue to add 74kg of asphalt to the synthetic rubber, stir for 30 minutes, then add 1kg of hydrotalcite FM300 calcium zinc stabilizer and 5kg of silicone oil defoamer, and then fully stir for 30 minutes to obtain the final product.

Embodiment 2

[0020] At 25°C, add 1kg glyceryl tristearate and 5kg fatty alcohol polyoxyethylene ether to 10kg natural rubber, stir thoroughly for 30min, then add 3kg paraffin oil, 2kg polyisobutylene and 10kg light calcium carbonate, and stir thoroughly for another 30min , to obtain synthetic glue. Continue to add 60kg of asphalt to the synthetic rubber, stir for 30 minutes, then add 4kg of hydrotalcite FM300 compounded calcium zinc stabilizer and 5kg of silicone oil defoamer, and then fully stir for 30 minutes to obtain the final product.

Embodiment 3

[0022] At 25°C, add 1kg of vinyl bisstearamide and 5kg of softening sodium dodecylbenzenesulfonate to 6kg of natural rubber, stir thoroughly for 30 minutes, then add 5kg of paraffin oil, 5kg of polyisobutylene and 12kg of talcum powder, and then fully stir After 30 minutes, synthetic glue was obtained. Continue to add 59kg of asphalt to the synthetic rubber, stir for 30 minutes, add 2kg of hydrotalcite FM300 compounded calcium zinc stabilizer and 5kg of silicone oil defoamer, and then fully stir for 30 minutes to obtain the final product.

Abstract

The invention relates to a water-based damping adhesive. The water-based damping adhesive comprises, in percentage by weight, 55%-80% of asphalt, 6%-20% of rubber, 0.1%-6% of a dispersing agent, 5%-10% of a surfactant, 5%-25% of a filler, 0.3%-5% of a cross-linking agent, 2%-10% of a softener, 0.2%-3% of an additive, 0.2%-7% of a hydrotalcite FM300 compounded calcium-zinc stabilizer and 5%-10% ofa silicone oil defoamer, wherein the rubber is one or a mixture of two selected from natural rubber and water-based nitrile butadiene rubber; the softener is one or a mixture of two selected from paraffin oil and naphthenic oil; the cross-linking agent is one or a mixture of two selected from polyisobutene and polybutylene; and the filler is composed of one or more selected from light calcium carbonate, talcum powder and bentonite.

Description

technical field [0001] The invention relates to water-based damping glue. Background technique [0002] Most of the existing damping glues are oily (solvent-based) antirust glues, water-soluble antirust glues, and composite polymer resin paint glues. These products have the following problems when applied: [0003] 1. Oil-based products contain toxic substances (solvents used as diluents, such as toluene) that are harmful to the human body, which will damage the environment and human health. In addition, the adhesive layer of oil-based (solvent-based) products is very hard. If it is slightly bent, the adhesive layer will crack, lack elasticity, and have poor sound insulation effect. [0004] 2. Water-soluble anti-rust glue is poisonous, has strong adhesion, is easy to pollute the environment, and has a remarkable sound insulation effect. However, the construction is greatly affected by temperature and humidity and takes a long time. [0005] 3. Composite polymer resin pai...
