Description

Environment-friendly flame-retardant sound-absorbing sandstone composite board

Technical Field

The utility model relates to a building decoration plate technical field specifically is fire-retardant sound sandstone composite sheet of inhaling of environment-friendly.

Background

With the continuous improvement of living standard of people, the requirements for living environment are also improved, so that the sound-absorbing material is widely applied to building decoration. The sound absorbing material is a material having a strong sound absorbing property and a noise reducing property. One of the sound absorbing materials is a porous material which attenuates sound waves by a plurality of fine open pore channels from the surface to the inside, and mainly absorbs medium-high frequency sound waves, and comprises various organic or inorganic fibers with fibrous aggregation tissues, products thereof, open-cell foam plastics with a porous structure and expanded perlite products. At present, sound-absorbing materials have various varieties and various advantages and disadvantages, poor fireproof grade, fear of collision after decoration, poor integral effect of surface layers, poor environmental protection and other adverse phenomena, and are difficult to adapt to the requirements of modern building development.

SUMMERY OF THE UTILITY MODEL

To the technical problem, the utility model provides an environment-friendly is fire-retardant inhales sound sandstone composite sheet when the sound is inhaled to the high efficiency, has high fire-retardant grade, and surface strength is higher, and impact resistance is higher, and the feature of environmental protection is good.

In order to solve the technical problem, the utility model discloses a technical scheme is: the environment-friendly flame-retardant sound-absorbing sandstone composite board comprises a sandstone layer, a polyester fiber layer, a grid cloth layer and a base layer, wherein the thickness of the sandstone layer is 2-4 mm.

According to the environment-friendly flame-retardant sound-absorbing sandstone composite plate, the sandstone layer comprises the white marble sand grains of 20-40 meshes and the adhesive layer coated on the surfaces of the white marble sand grains.

According to the environment-friendly flame-retardant sound-absorbing sandstone composite plate, the sandstone layer comprises 20-40 meshes of sea sand and a binder layer coated on the surface of the sea sand. In the environment-friendly flame-retardant sound-absorbing board, the base layer is a non-woven fabric layer.

According to the environment-friendly flame-retardant sound-absorbing sandstone composite plate, micropores with the size of 0.5-1.0mm are distributed on the surface and the inside of the sandstone layer, and the thickness ratio of the polyester fiber layer to the sandstone layer is 3-5: 1.

According to the environment-friendly flame-retardant sound-absorbing sandstone composite plate, micropores with the size of 0.5-1.0mm are distributed on the surface and the inside of the sandstone layer, and the number of the micropores per square meter is 900-1200 thousands.

The utility model discloses fire-retardant sound sandstone composite sheet of inhaling of environment-friendly's beneficial effect is: the white marble sand has higher strength, and the strength of the sandstone layer is higher through the combination of the white marble sand and the adhesive; sandstone layer thickness is established to 2-4mm, and the proportion of thickness between simultaneous control polyester fiber layer and the sandstone layer makes the utility model discloses when keeping the high-efficient sound of inhaling, prevent to make its and polyester fiber layer's junction atress great and cause and drop because of the too thick heavy sandstone layer, because of the too thin polyester fiber's of messenger along micropore migration sandstone layer surface of sandstone layer, the sound sand bed of inhaling under this thickness can quick drying simultaneously, improves the efficiency of construction, resources are saved prevents the waste of material. Because the white marble sand grains and the water-soluble environment-friendly binder are non-combustible, and the polyester fiber is non-combustible in B1 grade, the sound-absorbing sand plate can reach flame retardant B1 grade, meanwhile, the polyester fiber is an environment-friendly material, and the white marble sand grains and the water-soluble environment-friendly binder are also environment-friendly materials, so the sound-absorbing sand plate has excellent environment-friendly performance.

Detailed Description

The present invention will be described in further detail with reference to fig. 1.

The environment-friendly flame-retardant sound-absorbing sandstone composite board comprises a sandstone layer 1, a polyester fiber layer 3, a mesh fabric layer 2 and a base layer 4, wherein the thickness of the sandstone layer is 2-4 mm. The sandstone layer comprises white marble sand grains of 20-40 meshes and a binder layer coated on the surfaces of the white marble sand grains. The base layer is a non-woven fabric layer. Micropores with the size of 0.5-1.0mm are distributed on the surface and the inner part of the sandstone layer, and the thickness ratio of the polyester fiber layer to the sandstone layer is 3-5: 1. Micropores with the size of 0.5-1.0mm are distributed on the surface and the inner part of the sandstone layer, the number of the micropores per square meter is 900-1200 ten thousand, and the pores of the micropores are 15-24 meshes.

The sandstone layer comprises 20-40 meshes of sea sand and a binder layer coated on the surface of the sea sand.

The thickness ratio between the polyester fiber layer and the sandstone layer is 3-5:1, and when the polyester fiber layer is impacted by external force, the polyester fiber layer 3 can buffer partial force, so that the damage to the sandstone layer 1 is reduced. The thickness of the sandstone layer is 2-6mm, micropores with the size of 0.5-1.0mm are distributed on the surface and the inner part of the sandstone layer 1, the number of the micropores on the surface per square meter is 900-1200 thousands, the number of a large number of micropores is beneficial to improving the sound absorption effect, the sound absorption coefficient can reach 0.6-0.85, and the sandstone layer and the polyester fiber layer have good sound absorption effect, so that the sound absorption coefficient of the environment-friendly flame-retardant sound absorption plate is larger than 0.9. The outer surface of the binder layer can be coated with chemical pigment, namely a colorant layer, so as to meet the requirement on the color of the sandstone layer.

The grid cloth layer is alkali-resistant grid cloth, has excellent alkali resistance, durability, high tensile strength and deformation resistance, can prevent the generation of cracks of the sandstone layer, has stable chemical properties, is not easy to deteriorate, and effectively improves the strength of the sandstone layer.

The adhesive layer is a water-based adhesive layer and can be fully filled in gaps among the white marble sand grains. The water-based adhesive generates micropores in the gaps due to the evaporation of water, particularly the evaporation of the water-based adhesive in the gaps among the white marble sand grains, and the micropores are enlarged along with the evaporation of the water to form mutually communicated micropores. When the water is completely evaporated, the residual water-based adhesive can be tightly coated on the surrounding white marble sand grains to form a film layer coating the white marble sand grains, so that the connection between the white marble sand grains is firmer. When the proper amount of environment-friendly polyurethane adhesive agent of addition in water-based adhesive, can increase the viscosity of binder, after moisture evaporation, can improve the micropore quantity and the size of sandstone layer, and then the sound absorption effect of reinforcing sandstone board, environment-friendly polyurethane adhesive agent has good wearability simultaneously, and the cladding is at the environment-friendly polyurethane adhesive agent on white marble sand grain surface, through collision friction back many times, is difficult for taking place the damage for white marble sand grain is difficult for droing, improves the life of panel.

Of course, the above description is not intended to limit the present invention, and the present invention is not limited to the above examples, and the changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present invention should also belong to the protection scope of the present invention.
