Abstract
The invention belongs to building material field, disclose a kind of wallboard composite material of heat preservation and soundproof waterproof, it is followed successively by mask paper, plaster matrix and mask paper from top to bottom; Be bonded by binding material between described plaster matrix and described mask paper; It is identical that upper and lower both sides obtain mask paper.The wallboard complex material heat preservation soundproof effect of heat preservation and soundproof waterproof prepared by the present invention is good, and water-fast moisture resistance is strong, is greatly better than market like product.
Description
Technical field
The invention belongs to building material field, be specifically related to a kind of wallboard composite material of heat preservation and soundproof waterproof.
Background technology
Construction wall heat insulating material comprises organic (as benzene plate, polyphenyl plate, extruded sheet, polystyrene foam plate, hard foam polyurethane, Merlon and phenolic aldehyde etc.), mineral-type (as perlite and cement plate, foamed cement board, composition silicate, rock wool, steam pressure sand aerated concrete block, conventional vacuum mortar etc.) and composite material class (if metal clip central layer, core are polyphenyl, glass bead, granular polystyrene etc.), thermal insulative anti-crack material: (electrowelding net, hot-galvanized steel silk screen, grid cloth).
Sound insulation for building material (Soundproof Materials), refers to a kind of material of the isolation of noise of propagating in air, partition, separation, component or structure.For sound insulating material, transmission acoustic energy be weakened, the propagation of block sound, just can not as sound absorption material porous, loose, ventilative, its material should be heavy and closely knit on the contrary, as class materials such as steel plate, stereotype, brick walls.The requirement of sound insulating material material is closely knit imporosity or gap; There is larger weight.Because this kind of sound insulating material is closely knit, be difficult to absorb and reflect through acoustic energy energy strong, so its sound absorbing capabilities is poor.Every material that can be used for block noise, is referred to as sound insulating material.Sound insulation materials is multifarious, and daily people compare and common are solid fragment of brick, reinforced concrete wall, plank, gypsum plank, iron plate, sound-insulating felt, fiberboard etc.
Waterproof materials for wall refers to that this material is when doing waterproof test according to U.S. ASTM standard, its water absorption rate is 5%, namely can be used in the region that humidity is larger, as washroom, shower room and kitchen etc., but be not directly exposed in moist environment, also not directly water inlet is long-time soaks.Its plate core and mask paper all have passed through waterproofing work, and according to the requirement of GB, waterproof materials for wall all must reach certain waterproof requirement (water absorbent surface amount is not more than 160 grams, and water absorption rate is no more than 10%).Waterproof materials for wall is applicable to the field of employment that continuous relative humidity is no more than 95%, as washroom, kitchen, bathroom etc.Chinese invention patent CN201010022499 discloses a kind of water-resistant gypsum board, but this gypsum plank water resistance does not reach international standard far away.
The wallboard composite material of prior art seldom can possess heat preservation and soundproof waterproof multi-functional, can not adapt to people's living needs; In view of prior art Problems existing, how preparing a kind of wallboard composite material of heat preservation and soundproof waterproof, is prior art technical problem urgently to be resolved hurrily.
Summary of the invention
In order to the heat preservation and soundproof weak effect that the wallboard composite material overcoming prior art exists, and the defect such as water-fast moisture resistance is low, the invention provides the wallboard composite material that a kind of various aspects of performance parameter is higher, it is much better than market common product.Meanwhile, present invention also offers the preparation method of this wallboard composite material.
The object of the invention is to be achieved through the following technical solutions:
A wallboard composite material for heat preservation and soundproof waterproof, it is followed successively by mask paper, plaster matrix and mask paper from top to bottom; Be bonded by binding material between described plaster matrix and described mask paper; The mask paper of upper and lower both sides is identical;
Described mask paper is prepared as follows and forms:
Prepare burden according to weight portion in pond with slurry: precipitated calcium carbonate 300-400 part, string 100-150 part, glass fiber 100-150 part, PLA 100-120 part, dimethyl silicone polymer 50-60 part, starch ether 20-30 part, ethyl acrylate 10-12 part, cornstarch 10-12 part, sodium phosphate trimer 10-12 part and water 100-150 part;
First the batching in pond with slurry is stirred and obtain slurry, then enter head box, make slurry be evenly distributed in fourdrinier part, enter vacuum system subsequently and carry out first step dehydration, take off the moisture of more than 50%, form half wet page; Half page wet enters squeezer and carries out second step dehydration, controlled pressure 30MPa, dewaters 60 minutes; Finally, enter dryer and carry out the 3rd step dehydration, control temperature is 120 DEG C, and the time is 15 minutes, namely obtains the mask paper that thickness is 2mm;
Described plaster matrix is prepared as follows and forms:
Following raw material is taken: land plaster 120 parts, 40 parts, kieselguhr, pyrite dust 30 parts, dolomite dust 20 parts, French chalk 10 parts, chitin 10 parts, borax 8 parts, polyvinyl alcohol 8 parts, starch ether 6 parts, hydroxyethylcellulose 6 parts, 2 parts, phenolic resins, sodium succinate 1 part and 50 parts, water according to weight portion; Above-mentioned raw materials is mixed, then put in mortar mixer, stir and obtain mixed slurry, then mixed slurry is injected die casting and become sheet material, the demoulding after sheet material solidifies, finally sheet material being placed in temperature is 60 DEG C, and humidity is in the hygrothermal environment of 60% 12 hours, obtains the plaster matrix that thickness is 10mm; The length of above-mentioned glass fiber is preferably 5-10mm;
Described binding material is prepared as follows and forms:
Ethylene-vinyl acetate resin (EVA) 5 parts, white glue with vinyl 3 parts, French chalk 2 parts, 1 part, agar and casein 1 part is got according to weight portion; Be uniformly mixed and get final product;
