firstly, 5% of sodium silicate, 6% of diatom ooze, 4% of titanium dioxide, 20% of resin, 0.6% of defoaming agent, 0.7% of film forming additive and 33% of deionized water are placed into a mixing reaction kettle to be stirred for about 10-15min, 30% of natural fibrilia and 0.7% of adhesive are placed into the mixing reaction kettle, and stirring is carried out for 5-10min, so that the sound-absorbing heat-insulating coating is prepared.
The detected free formaldehyde is 8.39mg/kg, and the content of volatile organic compounds is 108.6 g/l;
the sound absorption coefficient of the coating is determined to be more than or equal to 20% by adopting a standing wave tube method, and the heat-insulating coating is qualified within the range of 125HZ-4000 HZ.
Example 2
A sound-absorbable heat-insulation coating is prepared from the following components in percentage by mass: 20% of natural fibrilia, 7% of sodium silicate, 8% of diatom ooze, 5% of titanium dioxide, 22% of resin, 1.5% of adhesive, 1.3% of defoaming agent, 1.2% of film-forming assistant and 29% of deionized water.
