Problems solved by technology

However, at present, metal materials in the market are widely used in the form of plates, blocks, and strips.
Welding metal plates on one side of the wall is bulky, difficult to construct, and prone to rust.
The high-molecular elastomer polymer mixed with a large amount of metal powder can be pressed into various soft coils, plates, sheets, etc., which are convenient for people to cut and use in different fields, so as to solve the sound insulation problem of the current building walls

Embodiment Construction

[0013] Embodiment In the field of building sound insulation, soft elastic materials made of high specific gravity metal powders such as iron and steel are made into coils of different thicknesses, which can play a good role in sound insulation, and its softness and elasticity can be cut with a knife. It is very convenient to use.

[0014] To sum up, the application of powder metal composite sound insulation materials will have a very broad prospect.

Abstract

The invention provides a method for preparing a powder metal composite coiled material in the field of building sound insulation. The powdered metal composite coiled material includes high molecular elastomer polymer and metal powder. Among them, the particle size of the metal powder should be less than 1mm, and the high molecular elastomer polymer includes rubber, plastic, polyurethane, asphalt, etc., and there are many gaps in the three-dimensional network structure of the high molecular elastic polymer, and the metal powder is mixed into it , pressed into the required powder metal composite coil to meet the current requirements in the field of building wall sound insulation.

Description

technical field [0001] The invention is a method for preparing a powder metal composite coil suitable for the field of building sound insulation. Background technique [0002] At present, the country vigorously advocates land-saving and energy-saving buildings. Various buildings are getting taller and taller. In order to reduce the structural support load, the country vigorously promotes aerated bricks and bans solid bricks. In this way, the single wall of the building is getting lighter and lighter, which will bring An acoustic problem: the sound insulation performance of the wall is getting worse and worse, and it cannot meet the requirements of the relevant building sound insulation standards, because the sound insulation performance of the wall follows the "quality law", that is, the sound insulation performance of the wall is related to the quality of the wall per unit area. Proportional. At present, the common practice in the industry is to make a cavity on one side o...
