Problems solved by technology

However, glass windows are usually installed on the facade of the building to meet the ventilation and indoor lighting requirements of the building, and the glass windows account for about 20% of the building's facade, or even more, and the sound insulation of the glass windows The effect is poor, so the overall sound insulation effect of the building will be greatly reduced, especially in the residential area near the city's elevated road
In the prior art, people usually install double glazing on the windows to improve the sound insulation effect, but the construction of this method is complicated and the relative cost is high

Embodiment 1

[0043] Step 1, preparing a silica airgel aqueous dispersion;

[0044] Add 62.5 kg of deionized water into the pre-dispersion tank, start stirring, then add 3.2 kg of phenolic derivative non-ionic hyperdispersant of Hairun Chemical Co., Ltd. model DP2881 under stirring, stir and mix for 10 minutes after adding, and then Add 32kg of silica airgel particles from Tianjin Morgan Kunde High-tech Development Co., Ltd. at a speed of ~500 rpm and pre-disperse for 10-20 minutes, and then add the phosphate anions of Hairun Chemical Co., Ltd. DP2195 in turn under stirring 1.6kg of dispersant, 0.6kg of TU2881 polyurethane thickener from Hairun Chemical, 0.1kg of BS168 organosilicon pH regulator from Wacker, after adding, stir and increase the stirring speed to 1400-1600 rpm Disperse at high speed for 30 minutes, and then use a pin-type sand mill to grind for 1.5-2.5 hours before being used in step 2.

[0045] Step 2, prepare the A component of the airgel water-based two-component transpar...

Embodiment 2

[0050] Take each component according to the weight shown in Example 2 in Table 1, and repeat the method described in Example 1, except that 2 kg of component B is used in step 4, diluted with 2 kg of water, and added to component A. The performance testing results are shown in the corresponding data of Example 2 in Table 2.

Embodiment 3

[0052]Take each component according to the weight shown in Example 3 in Table 1, and repeat the method described in Example 1, except that 2 kg of component B is used in step 4, diluted with 2 kg of water, and added to component A. The performance testing results are shown in the corresponding data of Example 3 in Table 2.

Abstract

The invention provides an aerogel waterborne two-component transparent soundproof coating, and a preparation method and application method thereof. The coating is prepared through mixing of the following components according to parts by weight: a component A: 69-73 parts of waterborne polyurethane resin, 5.0-5.7 parts of a film forming agent, 0.2-0.4 part of an organic silicon defoamer, 0.2-0.4 part of an organic silicon substrate wetting agent, 0.3-0.5 part of an organic silicon flatting agent, 20-25 parts of silicon dioxide aerogel water dispersions, and 0.1-0.2 part of an antiseptic; a component B: a silane coupling agent with an epoxy structure; and the ratio of the component A to the component B: 100 to 1.5-2.5. The coating and the preparation method and application method thereof provided by the invention have the advantages that good lighting effects can be ensured, and outdoor noises can be effectively reduced, so that building glass achieves good decorative, lighting and soundproof effects, and the living environment of people is improved.

Description

technical field [0001] The invention relates to the field of functional water-based coatings for architectural decoration, in particular to an airgel water-based two-component transparent sound-insulating coating and its preparation and use methods. Background technique [0002] Urban noise mainly comes from traffic noise, industrial noise, construction noise, social life noise, etc. The disturbance and harm to residents are becoming more and more serious, and it has become a major public hazard to the urban environment. [0003] At present, for the high-rise buildings where people live and live, because of the thickness and material of the building walls, they should be able to have a good isolation effect on urban noise pollution. However, glass windows are usually installed on the facade of the building to meet the ventilation and indoor lighting requirements of the building, and the glass windows account for about 20% of the building's facade, or even more, and the sound...
