Sound-absorbing and heat-insulating brick and preparation method thereof
The invention discloses a sound-absorbing and heat-insulating brick. The sound-absorbing and heat-insulating brick comprises a heat-insulating blank and a sound-absorbing body; the heat-insulating blank is a hollow cuboid, and the heat-insulating blank is filled with the sound-absorbing body; and the heat-insulating blank is prepared from perlite, glazed hollow beads and chopped glass fibers, andthe sound-absorbing body is prepared from PU foam particles and PS foam particles. The perlite and the glazed hollow beads are adopted as main materials of the heat-insulating blank, thus the heat-insulating blank has heat-insulating and heat-absorbing effects, the mechanical strength of the heat-insulating blank can be enhanced by adding the certain number of chopped glass fibers, and thus the heat-insulating blank still has enough strength after a cavity is dug; as for the sound-absorbing body, the PU foam particles and the PS foam particles are adopted as a sound-absorbing main body, and the sound-absorbing main body is bonded into blocks through molten polyvinyl acetate and thus is easy to process into strips; and the hollow heat-insulating blank is filled with the sound-absorbing bodywith a sound-absorbing function to prepare the sound-absorbing and heat-insulating brick, and the sound-absorbing and heat-insulating brick has the heat-insulating and sound-absorbing functions and can be applied to nonbearing outer walls of buildings.
本发明公开了一种吸音隔热砖，吸音隔热砖包括隔热坯和吸音体，隔热坯为中空的长方体，吸音体填充在隔热坯内部；隔热坯包括珍珠岩、玻化微珠和短切玻璃纤维，吸音体包括PU泡沫颗粒和PS泡沫颗粒。本发明采用珍珠岩和玻化微珠作为隔热坯的主体材料，使隔热坯具有隔热吸热的作用，添加一定量的短切玻璃纤维可增强隔热坯的力学强度，从而保证开凿空腔后仍具有足够的强度；吸音体采用PU泡沫颗粒和PS泡沫颗粒作为吸音主体，用熔融的聚醋酸乙烯酯粘结成块状，易于加工成条状。本发明在中空的隔热坯中填充具有吸音功能的吸音体制备成吸音隔热砖，兼具隔热和吸音的功能，可应用于建筑物的非承重外墙。
