Sound-absorbing and heat-insulating building decoration material and preparation method

Abstract

The invention discloses a sound-absorbing and heat-insulating building decoration material and a preparation method. The material is prepared from the following raw materials: waste paper pulp, wood sawdust, high-viscosity attapulgite clay, an adhesive, vegetable fibers, a flame retardant, light calcium carbonate and quartz powder. The preparation method comprises the steps of mixing and uniformly stirring all the ingredients separately and thoroughly so as to obtain a size mixture, then, putting the size mixture in a die, then, putting the die in a plate vulcanizing machine, carrying out hot-press forming, and then, carrying out polishing treatment on a formed product, thereby preparing the sound-absorbing and heat-insulating building decoration material. The decorating material not only has relatively good sound-absorbing and heat-insulating effects, but also has certain flame retardance; the preparation method is easy and feasible and is applicable to industrial production application.

Description

technical field [0001] The invention relates to the technical field of building decoration materials, in particular to a sound-absorbing and heat-retaining building decoration material and a preparation method. Background technique [0002] At present, the roof and wall building materials used in the construction market are generally based on thermal insulation materials formed by compounding aluminum foil, plastic middle layer, and polyethylene foam cotton. The thermal insulation material described has the following disadvantages: polyethylene foam is a high-foamed polyethylene product produced by physical foaming and extrusion, and is composed of numerous single bubbles. The plastic foaming material is easy to burn and has poor flame retardancy. There are potential safety hazards in terms of fire performance; the middle layer of the thermal insulation material is a plastic layer, although the plastic layer increases the tensile strength of the thermal insulation material a...

Problems solved by technology

The thermal insulation material described has the following disadvantages: polyethylene foam is a high-foamed polyethylene product produced by physical foaming and extrusion, and is composed of numerous single bubbles. The plastic foaming material is easy to burn and has poor flame retardancy. There are potential safety hazards in terms of fire performance; the middle layer of the thermal insulation material is a plastic layer, although the plastic layer increases the tensile strength of the thermal insulation material and facilitates construction, but the plastic layer makes the flame retardancy of the thermal insulation material poor; the existing Insulation materials have poor sound-absorbing and noise-proof effects

However, it is difficult to increase the content of short polyester fibers in the material, because the tensile properties are greatly reduced, which makes it difficult to shape the material during the manufacturing process; due to the large number of thick fibers in the material, the sound absorption performance will be greatly reduced

These are all the performance barriers and difficult problems in the manufacturing process of the sound-absorbing and insulating materials based on the melt blown method.
