Film-coated heat-insulation sound absorption wool

Abstract

The invention relates to film-coated heat-insulation sound absorption wool which comprises glass wool and a film cover. The glass wool is flatly packaged in the film cover, adhesion portions are formed on two sides of the film cover, adhesive is coated on the surface of a side of each adhesion portion, release paper covers the adhesive, and conical dense tiny sound absorption holes are uniformly formed in the surface of a side or the surfaces of the two sides of the film cover and are protruded towards the outer side of the film cover. The film-coated heat-insulation sound absorption wool has the advantages that the film-coated heat-insulation sound absorption wool still mainly comprises the glass wool which is currently used as a heat-insulation sound absorption material, a layer of 'special' film covers the glass wool to form a novel heat-insulation sound absorption material, accordingly, shortcomings of impaired performance of the glass wool currently directly used as the heat-insulation sound absorption material due to easiness in absorbing water vapor and adsorbing dust and falling and stacking due to inconvenience in mounting the glass wool and difficulty in fixedly shaping and positioning the glass wool can be perfectly overcome, and multiple purposes can be achieved by the film-coated heat-insulation sound absorption wool; the film-coated heat-insulation sound absorption wool is smart in design, convenient to process and low in production cost and has an excellent popularization prospect.

Description

technical field [0001] The invention relates to a film-coated heat-insulating and sound-absorbing cotton, which is a building material used for installing in a wall interlayer to achieve heat-insulating and sound-absorbing effects. Background technique [0002] Heat insulation and sound-absorbing cotton is mostly used between the inner wall of the building wall and the decorative wall (gypsum board, wood board, etc.) to play the role of heat insulation and sound absorption. At present, glass wool is mostly used for heat-insulating and sound-absorbing cotton. During construction, glass wool is directly placed in the interlayer between the building wall and the decorative wall. The disadvantage of this method is that glass wool is easy to absorb air during long-term use. Moisture and moisture in it, and absorb a large amount of dust, which greatly weakens the heat-insulating and sound-absorbing effect of glass wool; moreover, if the height of the interlayer of the wall is high...

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved by the present invention is: currently, when glass wool is directly placed into the wall interlayer as a heat-insulating and sound-absorbing material, the glass wool is easy to absorb water vapor, absorb dust, and the glass wool is not easy to be fixed and positioned, resulting in falling and stacking. Defects, comprehensively cause the heat insulation and sound absorption effect of glass wool to be greatly weakened. Therefore, a kind of coated heat insulation and sound absorption cotton that can solve the above problems is provided.
