Description

Scratch-resistant sound-insulation leather wallboard
Technical Field
The invention belongs to the technical field of plate manufacturing, relates to a composite wallboard, and particularly relates to a scratch-resistant sound-insulation leather wallboard.
Background
The noise is the sound produced when the sounding body does irregular vibration, and is a common environmental pollution. Noise pollution is created when noise adversely affects people and the surrounding environment. Since the industrial revolution, the creation and use of various mechanical devices has brought prosperous and advanced to the human being, but at the same time, it has produced more and more intense noise. The noise can not only cause damage to hearing, but also induce a plurality of carcinogenic and fatal diseases, and interfere with life and work of people. Accordingly, attention is being paid to a sound insulating material capable of insulating, blocking and separating noise propagated in the air. For the sound insulation board, the transmitted sound energy is weakened, and the transmission of sound is blocked. Traditional sound insulation materials are heavy metals or inorganic materials, which are often heavy and heavy, limiting their range of use. The high polymer material has the advantages of light weight, good processing performance and the like, wherein the foam plastic can dissipate sound waves through stagnation and compression of gas in the air holes, and has a sound insulation effect. But the surface density and the elastic modulus are low, so that the practical application requirements are difficult to meet. Therefore, the new sound insulation board and structure become a research hotspot in the field of sound insulation, wherein the research on the light sound insulation material and structure is particularly interesting.

The technical purpose of the invention is realized by the following technical scheme:
the invention provides a scratch-resistant sound-insulation leather wallboard which sequentially comprises scratch-resistant flexible leather grain woven cloth, a PVC (polyvinyl chloride) plate A, a high-molecular sound-insulation felt, a PVC plate B and a silencing pad from top to bottom; the preparation method specifically comprises the following operation steps:
s1, preparing a scratch-resistant flexible leather grid woven fabric, and coating the surface of a piece of mesh fabric in three layers: the bottom coating, the middle coating is a foaming layer, and the top coating is a scratch-resistant layer;
s2, preparing a PVC plate A and a PVC plate B, namely producing the PVC plate A and the PVC plate B with the thickness of 2-5 mm by adopting a double-screw extruder;
s3, paving the scratch-resistant flexible leather grain woven cloth, the PVC plate A, the polymer sound-proof felt, the PVC plate B and the mute pad in sequence, and laminating through PUR glue.
Preferably, in step S3, the PVC plate B and the polymeric deadening felt are bonded together by using a two-component polyurethane or PUR hot melt adhesive; the scratch-resistant flexible leather grid woven fabric is attached to the PVC plate A by using PUR hot melt adhesive.
Preferably, in the preparation of the scratch-resistant flexible leather grid fabric, the surface of the mesh fabric is coated with three layers: the bottom coating, the middle coating is a foaming layer, and the top coating is a scratch-resistant layer;
and (3) base coating: penetrating into the sandwich mesh cloth, increasing the adhesive force between the sandwich mesh cloth and the middle foaming layer, and ensuring that the thickness is 0.1-0.2 mm;
an intermediate foaming layer: polyurethane resin is used, a foaming agent is added, and the material is subjected to micro-foaming in the forming process, so that the whole material has good elasticity and the thickness is 0.5-0.7 mm;
coating a scratch-resistant layer: the polyurethane resin is added with the auxiliary agent, and the auxiliary agent comprises polyethylene wax powder, silicon carbide and an organic silicon hand feeling agent, so that the surface of the material has excellent scratch resistance and smooth hand feeling.
Further, the PVC board A and the PVC board B are stone plastic boards, wherein the mass ratio of the PVC powder to the calcium powder is 1: 2.5-1: 3.3. PVC panel adopts stone to mould panel, not only can play the effect of fire prevention, can also prevent panel "arching" problem.
Furthermore, the polymer sound-proof felt is a composite material of metal compound powder and polymer fibers, wherein the mass ratio of the metal compound powder to the polymer fibers is 0.5: 1-0.8: 1. The sound absorbing material generally absorbs sound waves by buffering with large damping, and the method of the sound absorbing performance of the polymer porous material remarkably improves the sound absorbing performance in the middle and low frequency bands, but on the other hand, reduces the sound absorbing performance in the high frequency band. According to the invention, the metal compound powder is loaded in the polymer fiber, so that on one hand, the large pore channels in the disordered and crosslinked polymer fiber are blocked by the metal compound, and more and finer pore channels are formed, so that the polymer fiber not only has the damping and sound-absorbing capacity, but also has the resonance and sound-absorbing capacity, and the problem of poor low-frequency absorption of the polymer fiber is solved.
Further, the metal compound powder is Fe3O4@C、Bi2O3@ C or WO3-MoO3@ C. The three kinds of metal compound powder respectively contain a disordered layer structure formed by random accumulation of molecular fragments of a two-dimensional graphite layer and/or a three-dimensional graphite microcrystal, and can well adsorb low-frequency sound waves; while Fe3O4The glue can be formed after meeting water, so that the glue has an adsorption and phagocytosis effect on bacteria, the waterproof capacity of the board is improved, and meanwhile, the antibacterial capacity of the board is improved; bi2O3The glass ceramic plate has the advantages of having the performance of glass ceramic and low heat conductivity coefficient, and greatly improving the high temperature resistance and the fire resistance of the plate; WO3-MoO3The energy of sound waves can be absorbed through the change of the energy band structure, and the purposes of sound absorption and sound insulation are achieved.
Further, the polymer fiber is a multi-component composite polymer fiber and comprises the following components in parts by weight: 180-200 parts of polyacrylamide, 150-180 parts of main chain type benzoxazine resin, 80-90 parts of BeO porcelain, 35-40 parts of hydroxypropyl methyl cellulose, 70-80 parts of asbestos wool, 4-8 parts of a coagulant, 3-6 parts of a curing agent and 10-15 parts of a foaming agent. The main chain type benzoxazine resin can form a disordered cross-linking structure of a space three-dimensional network, and the specific surface area of a disordered pore channel is improved, so that the sound absorption capacity of the benzoxazine resin is improved, but the benzoxazine resin has certain high-temperature brittleness; and the BeO porcelain can also absorb the energy in the sound waves through the change of the energy band, thereby improving the sound absorption capability of the plate.
Further, the accelerator is calcium zincate. On the other hand, calcium zincate is used as a coagulant to promote the polymerization of the polymer fibers, and on the other hand, the alkalinity of the calcium zincate is utilized to react with part of BeO to form crystals such as calcium beryllide and the like, and the crystals are filled into the polymer fibers, so that the strength of the polymer fiber composite is improved.
Furthermore, the mute pad is made of a high-density crosslinked polyethylene foam material with the thickness of 1-3 mm.
Further, the surfaces of the PVC sheet A and the PVC sheet B have microtexture. The microtexture has certain buffering to the sound wave, plays syllable-dividing effect, on the other hand, improves the power of being connected of PVC panel and other layers, and then improves the life of panel.
Furthermore, the microtexture is in a cross grid shape; the groove width of the microtexture is 20-40 mu m, the depth is 20-40 mu m, and the spacing is 50-100 mu m.
In conclusion, the invention has the following beneficial effects:
the scratch-resistant sound-insulation leather wallboard provided by the invention adopts a brand-new environment-friendly raw material, takes a halogen-free renewable polymer as a raw material, is green and environment-friendly, and does not contain formaldehyde, benzene, asbestos, radioactive substances and other components harmful to human bodies. Does not contain ozone-destroying substances, and completely meets the international emission standard of volatile organic compounds. The polymer sound insulation felt provided by the invention fully utilizes the mass law and damping principle of building acoustic materials, and effectively absorbs and cuts off the noise transmitted through the building structures such as walls, ceilings and floors. The strong damping and the dough density greatly improve the sound insulation quantity of the raw materials. The composite material is compounded on the surface of the material, and the sound insulation quantity of the original material is improved to 10-29 dB.
