Sound insulation and heat insulation material and preparation method thereof

Abstract

The invention discloses a sound insulation and heat insulation material which comprises, by weight, 100-120 parts of natural ore, 40-60 parts of natural fibers, 30-50 parts of organic fibers, 10-40 parts of aluminum silicate fibers, 60-90 parts of sound insulation particles, 80-100 parts of heat insulation particles, 30-50 parts of glass beads, 20-40 parts of ceramic particles, 30-50 parts of Di(2-ethylhexyl)phosphate, 2-7 parts of polyethylene glycol, 2-6 parts of antioxidants, 4-8 parts of plasticizers, 1-3 parts of high-temperature ceramic glue, 2-5 parts of flame retardants, 1-3 parts of foaming agents and 120-140 parts of water. The sound insulation and heat insulation material has good sound insulation and heat insulation performance, barriers noise pollution and is environmentally friendly and efficient in energy, added glass bead particles have compact shells and hollow interiors, propagation paths of sound waves can be effectively prolonged, loss of the sound waves is increased, and sound insulation effect is further enhanced.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a sound insulation material and a preparation method thereof. Background technique [0002] With the development and progress of society, people's living standards have been greatly improved, and the degree of modernization is getting higher and higher. With modern factory equipment, more convenient transportation and rich daily life, but at the same time it also brings more many issues, such as "noise", "pollution", "congestion" and "energy". "Noise" has brought great distress and serious harm to people's life, study and spirit. At the same time, people have higher and higher requirements for living environment, work and study environment. On the one hand, these noises radiate directly through the wall, and on the other hand, they are transmitted to the room through the wall. Therefore, noise control and blocking have become an important problem that needs to be so...

Problems solved by technology

[0003] With the progress of society, the country has higher and higher requirements for industrial production or construction. Among them, various materials have put forward requirements for sound insulation, flame retardancy, heat insulation, and heat preservation. At present, in the fields of industrial production or construction in my country, For some board materials, inorganic foam materials, polymer organic foam materials, etc. are usually used to meet the requirements of sound insulation and heat insulation, but most of those materials are harmful to the human body and are flammable, so it is troublesome to recycle and dispose of their waste. Usually those materials are large in size and heavy in weight, which affects their performance. Therefore, the flame retardancy, environmental performance, mechanical properties, and convenience of construction and installation of building materials have attracted more and more attention.
