Abstract
An efficient composite sound-insulating board for building is composed of the substrate, the central layer and the surface layer. Said substrate is prepared from the ethylene-vinyl acetate, adhesive, parting agent and foaming agent. Said central layer is prepared from ethylene-vinyl acetate, porous promoter, adhesive, parting agent and foaming agent. Said surface layer is prepared from ethylene-vinyl acetate, polyethylene, porous promoter, addhesive, parting agent and foaming. Its advantages are high thermal and acoustic insulation, and a certain compression strength.
Description
Technical field
The present invention relates to a kind of building sound insulation materials, particularly relate to a kind of building flooring sound insulating sheet material.
Background technology
Press, high-rise building, public buildings such as especially high-rise resident apartment when making ground, at first will make the reinforcing bar keel, and then make ground and comb is installed with concrete on floor.The ground of Pu Sheing in this way, its sound insulation value is poor, and noise upstairs is easy to pass to normal life and the work that influences people downstairs.For this reason, once proposed on floor, to lay scrap rubber or low-density foamed resin to form the scheme of puigging.Though scrap rubber or low-density foamed resin bed have certain soundproof effect,, thereby can not keep its sound insulation function for a long time owing to the weight that is difficult to bear ground and comb goes to pot.
Summary of the invention
Purpose of the present invention promptly is to provide a kind of good soundproof effect that both had, and has the building flooring sound insulating sheet material of certain compressive strength again.
To achieve these goals, bottom, intermediate layer and the surface course compound pressure expansion of utilization of the present invention with certain thickness and different densities made a kind of composite highly effective structural insulating board material.Bottom is by EVAc and add jelly, mould release and blowing agent and mix compacting by suitable proportioning and form; The intermediate layer by EVAc and how empty matter accelerator, add jelly, mould release and blowing agent and mix compacting by suitable proportioning and form, its density is greater than bottom density; The surface by EVAc and polyethylene and how empty matter accelerator, add jelly, mould release and blowing agent and mix compacting by suitable proportioning and form, its density is greater than intermediate layer density.
In above-mentioned sound insulating sheet material, because the density and the thickness of bottom, intermediate layer and surface course have nothing in common with each other, each layer is all inequality to the propagation rate of the absorptivity of noise and noise, and therefore above-mentioned sound insulating sheet material will have good sound insulation value, also have certain compression strength simultaneously.When density of suitable each layer of increase and thickness, can strengthen its soundproof effect and compressive strength.Be described in further detail below in conjunction with the technical characterictic of specific embodiment composite highly effective structural insulating board material of the present invention.
Description of drawings
Fig. 1 is the structural representation of composite highly effective structural insulating board material of the present invention.
The specific embodiment
As shown in Figure 1, composite highly effective structural insulating board material of the present invention is to be made by bottom 1, intermediate layer 2 and surface course 3 compound pressure expansions; The bottom of bottom 1 evenly is formed with most projections 4, and the height of projection 4 is 7 ± 1mm.Bottom 1 is by EVAc 92.74% and add jelly dicumyl peroxide 0.96%, and mould release zinc stearate 0.74% and blowing agent azo dicarbonamide 5.56% mix compacting and form, and its thickness is 2 ± 1mm, and its density is 0.079g/cm
3Intermediate layer 2 by EVAc 73.206% and how empty matter accelerator calcium carbonate 18.302%, add jelly dicumyl peroxide 0.732%, mould release stearic acid 0.732% and blowing agent azo dicarbonamide 7.028% and mix compacting and form, its thickness is 6 ± 2mm, and its density is 0.0918g/cm
3Surface course by EVAc 37.994% and polyethylene 37.994% and how empty matter accelerator calcium carbonate 15.198%, add jelly dicumyl peroxide 0.760%, mould release stearic acid 0.760% and blowing agent azo dicarbonamide 7.294% and mix compacting and form, its thickness is 7 ± 2mm, and its density is 0.0996g/cm

When making above-mentioned sound insulating sheet material, at first the raw material of each layer is dropped into respectively to heat in the foamed plastic pressure initial refining machine by proportioning and mix, and then compound is dropped into roller be pressed into laminar primary product.After treating that each layer primary product compacting is finished, again that each layer primary product is compound in regular turn and put into heating pressure expansion moulding in the hot press.Moulding form can make the bottom of bottom evenly form most projections, and the shape of projection can be hemispherical, hexagon, quadrangle or other polygonals.
During use,, treat to re-lay this sound insulating sheet material and make projection down after the concrete setting earlier at floor upper berth one layer concrete, and then tubing and last layer concrete.Because the density and the thickness of each layer of sound insulating sheet material have nothing in common with each other, each layer also has nothing in common with each other to the absorptivity of noise and the noise speed by each layer; And, form air layer between bottom projection and the concrete.Therefore, the present invention has good sound isolating and heat insulating performance and has certain compression strength.
