Embodiment 1

[0029] Weigh each component raw material according to the following composition formula:

[0030]

[0031] The preparation process is as follows:

[0032] a) Forcibly blending the emulsion-type acrylate pressure-sensitive adhesive with the polyacrylate copolymer for 15 to 60 minutes to prepare emulsion A;

[0033] b) uniformly add the filler into the water, stir for 20-50 minutes, add a thickener, a surfactant, a defoamer, a flame retardant and a bactericide, stir for 10-30 minutes to mix evenly, and prepare slurry B;

[0034] c) Add the prepared emulsion A into the slurry B, and stir for 15-40 minutes to obtain.

[0035] According to the ASTM-E-756-98 standard, the water-based viscoelastic damping and sound-insulating adhesive described in this embodiment maintains a damping platform with a damping value above 0.9 between 7°C and 132°C.

[0036] According to GB-T2791-1995, the T-peel strength of the water-based viscoelastic damping sound-insulating adhesive described in ...

Embodiment 2

[0038] Weigh each component raw material according to the following composition formula:

[0039]

[0040] The preparation process is the same as described in Example 1.

[0041] According to the ASTM-E-756-98 standard, the water-based viscoelastic damping and sound-insulating adhesive described in this embodiment maintains a damping platform with a damping value above 0.9 at a temperature between -22°C and 83°C.

[0042] According to GB-T2791-1995, the T-peel strength of the water-based viscoelastic damping and sound-insulating adhesive described in this embodiment is 53 N / cm.

Embodiment 3

[0044] Weigh each component raw material according to the following composition formula:

[0045]

[0046] The preparation process is the same as described in Example 1.

[0047] According to the ASTM-E-756-98 standard, the water-based viscoelastic damping and sound-insulating adhesive described in this embodiment maintains a damping platform with a damping value above 0.9 between -9°C and 102°C.

[0048] According to GB-T2791-1995, the T-peel strength of the water-based viscoelastic damping sound-insulating adhesive described in this embodiment is 46.8 N / cm.

[0049] In summary, it can be seen that the water-based viscoelastic damping and sound-insulating adhesive of the present invention is an environmentally friendly adhesive, non-toxic and harmless, friendly to the human body and the environment, and has high damping value, wide temperature range, strong cohesiveness, and a damping value The damping platform above 100°C in the temperature range above 0.9, T-peel streng...

Abstract

The invention discloses a water-based viscous-elastic damping sound-insulation adhesive, comprising 40-80 wt% of emulsion aclylate pressure-sensitive adhesive, 0-10 wt% of polyacrylate copolymer, 0-15 wt% of filling material, 0-10 wt% of tackifier, 0.3-2 wt% of surfactant, 0.1-0.5 wt% of antifoaming agent, 1-4.0 wt% of fire retardant, 12-40 wt% of water, and 0.05-0.3 wt% of bactericide, wherein the summation of the weight percentages of all the ingredient is 100 wt%. The water-based viscous-elastic damping sound-insulation adhesive belongs to an environment-friendly type adhesive, has no toxicity and no harm, is friendly to human body and environment, has high damping value, wide temperature range, and strong caking property, can form a damping platform with a damping value of more than 0.9 and a temperature range of more than 100 DEG C, has a T-peel strength of larger than 31 N/cm, and has the dual effects of sound insulation and caking.

Description

technical field [0001] The invention relates to an adhesive, in particular to a water-based viscoelastic damping sound-insulating adhesive. Background technique [0002] With the improvement of people's living standards, people pay more and more attention to the noise in buildings, including the sound insulation of walls, ceilings, floors and other components. The fields of building sound insulation include residences, KTVs, bars, cinemas, recording studios, etc. At the same time, products with high sound insulation performance have gradually become the darling of the market. [0003] The traditional wall sound insulation methods include increasing the quality and thickness of the wall, using double-layer keel and multi-layer gypsum board to form a lightweight wall, and using fiber cotton, sound insulation felt, elastic rubber and other sound insulation products. However, these methods will make the sound insulation project more complicated, the installation is cumbersome, ...
