Embodiment 1

[0043] First, select three kinds of colored sand particles with a particle size of 0.25-0.425mm and colors of Phoenix Green, Grassland Green, and Hailan, and place them in their respective sealing devices according to different colors, and then start the vacuum cleaner connected to the top of the sealing device. Close after removing the mud and dust in the colored sand particles; then fully mix the above three colored colored sand particles with two-component epoxy resin with an amount of 8% of the colored sand particle mass and stir evenly, so that the three colors of colored sand particles The outer surface of the colored sand particles is covered with a layer of two-component epoxy resin with uniform thickness, and the curing agent is added at the same time or subsequently; at the same time, two pieces are placed at the specified positions in the 8mm thick colored sand sound-absorbing panel forming mold. The shape of the arc-shaped partition divides the forming mold into thr...

Embodiment 2

[0045] First, select five kinds of colored sand particles with a particle size of 0.425-0.85mm and colors of silver gray, gray jade, sapphire, white marble and evergreen, and place them in their respective sealing devices according to different colors, and then start the sealing device connected to the top. Vacuum cleaner, remove the mud and dust in the colored sand particles and turn off; then fully mix the colored sand particles with the color of silver gray and gray jade with the two-component epoxy resin with an amount of 10% of the mass of the colored sand particles and stir evenly, at the same time Fully mix the colored sand particles of sapphire, white marble and evergreen with the two-component epoxy resin with an amount of 15% of the mass of the colored sand particles and stir evenly, so that the outer surfaces of the colored sand particles of the five colors are covered with a layer of thickness Uniform two-component epoxy resin, add curing agent at the same time or l...

Abstract

The invention relates to a sound absorption plate for a building, and discloses a color-sand sound absorption plate. The color-sand sound absorption plate (1) is an integrally formed plate composed ofat least two sub sound absorption plates (2) with different colors, wherein each sub sound absorption plate (2) is formed by bonding a binding agent with color-sand particles which have a color corresponding to the color of the sub sound absorption plate, the binding agent covers the outer surfaces of the color-sand particles, the color-sand particles are combined through the bonding agent, and gaps among the color-sand particles covered by the binding agent form sound absorption pores. The color-sand sound absorption plate provided by the invention has good sound absorption performance and excellent decoration performance; the decoration effect can be designed according to the situation, and can be freely transformed and combined; and in addition, the color-sand sound absorption plate also has the advantages of simple preparation process and low manufacturing cost.

Description

technical field [0001] The invention relates to a building sound-absorbing board, in particular to a colored sand sound-absorbing board with both sound-absorbing performance and decorative effect. Background technique [0002] The porous sound-absorbing material itself has a large number of open and interconnected voids. The sound waves enter the material along these micropores, causing the air in the voids to vibrate. , part of the sound energy is converted into heat energy and lost. Common porous sound-absorbing materials include mineral wool, glass wool, polyester fiber, wood wool board, aluminum foam, etc. However, most porous sound-absorbing materials are not very decorative, or the production process is relatively complicated. [0003] The Chinese invention patent with the announcement number CN104108902B announced on May 11, 2016 discloses a particle sound-absorbing panel and its preparation method, which is to cover a layer of adhesive on the outer surface of the s...
