Heat-retaining and sound-insulating metal decorating plate

Abstract

The invention discloses a heat-retaining and sound-insulating metal decorating plate which comprises a metal heat-retaining baseplate and a sound-insulating decorating layer. The heat-retaining and sound-insulating metal decorating plate is characterized in that the metal heat-retaining baseplate comprises a first steel plate, a heat-retaining foam layer and a second steel plate sequentially from left to right, each of the first steel plate and the second steel plate is phosphorized, and the heat-retaining foam layer is formed by enabling rigid polyurethane foam premixed polyether and polymerized MDI to directly reacting between the first steel plate and the second steel plate. Compared with the prior art, the heat-retaining and sound-insulating metal decorating plate has the advantages that danger that heat-retaining materials are prone to catching fire is avoided, and the surface of each of the first steel plate and the second steel plate is phosphorized, so that corrosion resistance is realized, service life of the plate is prolonged, contact area between the heat-retaining foam layer and the steel plates can be increased, and combining is firmer while shedding is avoided; phosphorizing liquid enables films to be loose and porous in structure, so that sufficient contact area between the steel plates and the heat-retaining foam layer is guaranteed, and the plate is enabled to be firmer and more durable.

Description

technical field [0001] The invention relates to the field of building decoration materials, in particular to a heat-insulating and sound-insulating metal decorative plate. Background technique [0002] In modern house decoration, people have higher and higher requirements for personal privacy and living comfort. With the call of the country for energy conservation and emission reduction, house decoration is also paying more and more attention to the requirements of heat preservation. The commonly used decoration and heat preservation scheme is to directly spray foam on the inner wall, and then attach the decoration board. If sound insulation is required, another sound insulation decoration scheme is required, which not only takes up limited indoor space, but also requires Many materials also cause certain pollution to the indoor environment, making the renovated house unsuitable for living in a short period of time. In practice, we found that due to the insufficient adhesiv...

Problems solved by technology

The commonly used decoration and heat preservation scheme is to directly spray foam on the inner wall, and then attach the decoration board. If sound insulation is required, another sound insulation decoration scheme is required, which not only takes up limited indoor space, but also requires Many materials also cause certain pollution to the indoor environment, making the renovated house unsuitable for living in a short period of time

In practice, we found that due to the insufficient adhesive force and poor impact resistance strength of the polyurethane combined foam material, it is easy to shake off the mold and fall off. However, the polyurethane combined foam material is directly used in interior decoration, because of its low ignition point, it is also extremely easy to cause fire
