Description
Technical field
The present invention relates to a kind of Building Decoration Material, specifically is a kind of sound-absorbing sheet material that is used to be installed on the body of wall.
Background technology
Present known sound-absorbing sheet material is that board making is become cellular, is between the Kong Yukong by retardation most of acoustic energy to be consumed after irregular connection and be labyrinth-like, sound wave enter the sheet material of labyrinth-like, to reach the purpose of sound-absorbing.Hollow brick for example, the plate-like damping material that light porous materials such as slag, steel slag and perlite are made, though the loose structure of the abatvoix that this material is made has the good sound absorption effect, but must cause its intensity to reduce because its density is low, installing and fixing also of this material has difficulties, and quality is coarse, the defective of appearance luster difference but also exist.
Summary of the invention
Purpose of the present invention just provides a kind of preparation method of above-mentioned abatvoix, and preparation method provided by the invention comprises following process:
A, with crossing sieve classification after the sol particle shape auxiliary material drying, be divided into some grades from 80 mesh particle to 12 mesh particles, to obtain the homogeneous granules skeleton;
B, provide a mould that is used to hold, place above-mentioned grain skeleton, and grain skeleton is given compacting;
C, resin raw material and curing compound injected the mould of grain skeleton;
Carry out the demoulding after d, the curing;
E, place fresh water to dissolve the sol particle skeleton the said goods.
The technology scheme of putting disclosed by the invention is that the processing quality is light, intensity is high, can be used for the abatvoix of incrustation.
As shown from the above technical solution, abatvoix provided by the invention is to be made of resin, and the through-hole structure of labyrinth-like is arranged on the plate body.
If the area of the unit plate body that requires when making is bigger, can consider has reinforcing rib around abatvoix, and helps installing and fixing easily after reinforcing rib is set.
Being to use resin material by abatvoix provided by the invention is raw material, particle with solubility is a skeleton, the particle of solubility can be selected Nacl, sugar and vanadium etc. for use, resin is made foam-like resin with labyrinth-like through hole, to reach the purpose of sound-absorbing, its logging material is functional and ornamental in one, also has light weight, hard, beautiful in colour, remarkable advantage that sound-absorbing effect is good; The preparation method of abatvoix provided by the invention has selected the Nacl that can the dissolve grain skeleton as solubility for use, treats that abatvoix machines to be placed in the fresh water, and grain skeleton can make things convenient for, promptly dissolve.
Summary of drawings

Fig. 3 is overlooking of Fig. 1;
Fig. 4 is the equipment schematic diagram of the present invention under pressurized state.
The specific embodiment
The present invention is described in further detail below in conjunction with drawings and Examples.
As shown in Figure 1, 2, abatvoix provided by the invention is to be made of resin, and the through-hole structure of labyrinth-like is arranged on the plate body 10.Because abatvoix disclosed by the invention has good whole intensity, if the cellar area of plate body 10 is of moderate size, the intensity that relies on himself just can satisfy the requirement of installation, if area is bigger, can consider to add reinforcing rib 20 around abatvoix, reinforcing rib 20 is selected the entity resin for use.The thickness of reinforcing rib 20 is more than or equal to the thickness of plate body 10 around the abatvoix.The abatvoix that is obtained by the present invention has good sound-absorbing effect.The present invention has good performance, and specific targets are seen " sound-absorption coefficient examining report ".
In order to simplify preparation technology and to enhance productivity, the invention provides the method moulding of pressurization injection moulding, specifically exactly described resin raw material and curing compound are injected mould by pressed gas.
Referring to Fig. 4, described mould 3 is loop-like framework, the shape of mould can be square, rhombuses etc. are convenient to be spliced into the geometry of big face, on its upper and lower side has, lower seal plate 1,2, place grain skeleton in the described mould 3, offer material hole 5 and steam vent 6 on the mould 3, storage tank 9 tops have air inlet to link to each other with pressure gas source, storage tank 9 bottoms have relief hole to link to each other with injection molding joint 7 with material feeding conduit 8, injection molding joint 7 is connected with aforesaid material hole 5, and pressed gas process pipeline is with between the grain skeleton in the injection of the resin raw materials in the storage tank 9 mould 3.When injection moulding, should consider the sealing between injection molding joint 7 and material hole 5 connecting portions and upper and lower sealing plate 1,2 and the described mould 3, be full of each position of the grain skeleton in the mould, thereby obtain the uniform abatvoix of compact substance to guarantee resin raw material.
With epoxy resin is example explanation preparation method's particular content.
Select for use Nacl as the soluble particles auxiliary material among the present invention, be dried the back and cross sieve classification, from 80 mesh particle to 12 mesh particles, be divided into several grades, to obtain even-grained particle precast framework.(when abatvoix thickness is identical with the grain skeleton compacted density, the abatvoix that different mesh grade skeletons is made, its sound-absorption coefficient peak of curve difference.) grain skeleton is put into ready mould compacting.Compacted density is not less than 0.9 gram/cm
3, and be preheating to about 70--80C.
With unsaturated polyester or epoxy resin raw material and curing compound polyamide each 50%, be preheating to respectively about 60--70C, make it have good flowability.Different naval stores preheat temperature differences.Having good flowability with it is using priciple.With the two mixing, add pigment simultaneously and stir rapidly again, pour in the mould of having smeared release agent, allow its naturally osmotic inside, can slowly pour into simultaneously, guarantee exhaust air, prevent to produce bubble from one or more with being in harmonious proportion good resin.Treat curing and demolding.
Product after the demoulding is cut into required size, six polishings are level and smooth, tow sides polishings is to manifesting the homogeneous granules skeleton, and when the reinforcing rib thickness of product during greater than abatvoix, reverse side can suitably leave circular arc in corner's polishing of grain skeleton does not influence result of use.Polish again or be polished to required fineness in the front.
The product that processes is put into fresh water dissolve the soluble particles skeleton.Form the irregular through hole of labyrinth-like, dehydrate into final products then.
The product front, reinforcing rib and abatvoix are unified plane, and product reverse side, reinforcing rib height can be equal to or higher than abatvoix, and the space that the reinforcing rib the raised area surrounds can be used to adjust acoustic efficiency according to actual needs.For example change the reinforcing rib gauge, or fill other cheap damping material at the place, space.
During the casting product, the reinforcing rib of product part is not used soluble grain skeleton in the mould, and uses other filler to gain in strength and to reduce cost.
Reinforcing rib and abatvoix part can once become the mould pouring, also can the gradation casting or respectively casting be bonded as one again.
The graphical distribution of reinforcing rib can be patterns such as square shape, three-back-shaped, matrix pattern, groined type, arc, dihedral, curve and is used to gain in strength and beautify product.
Different with above-mentioned technology contents is, when using that for example 191#, 196# unsaturated polyester resin are as raw material, does not need preheating, promptly can pour into a mould at normal temperatures, and its proportioning ratio is as the criterion according to the description of product, and all the other contents can be with reference to previous embodiment.
