Description
Technical field
The present invention relates to materials for wall, relate in particular to adiabatic light gypsum sheet material of a kind of sound insulation and preparation method thereof.
Background technology
Wall board has lightweight, high-strength, multi-functional feature, is convenient to dismounting, and planar dimension is large, and construction efficiency is high, improves body of wall function; Thin thickness, can improve indoor usable floor area; Conduct oneself with dignity little, can alleviate building to basic load-bearing requirement, reduce construction costs, therefore greatly developing light wall board is the trend of materials for wall reform. Gypsum sheet material is a kind of material of making taking plaster of Paris as primary raw material, it be a kind of lightweight, intensity is higher, thinner thickness, easy to process and sound insulation is adiabatic and the construction material of the better performances such as fire prevention, is one of novel light sheet material of current development emphatically. Plasterboard has been widely used in internal partition wall, body of wall cladding boards, ceiling, abatvoix, surface based laminate and the various decorative panels etc. of the various buildings such as house, office building, shop, hotel and industrial premises. The plasterboard that China produces mainly contains Thistle board, decorated gypsum board, gypsum hollow lath, fibrous plaster, gypsum abatvoix, locating-point plasterboard etc.
Thistle board is taking gypsum slip as sandwich, and two sides paper using is done a kind of light weight board that mask forms. Thistle board quality is light, intensity is high, fire prevention, mothproof, be easy to processing. Common paper surface gypsum board is for interior wall, partition wall and furred ceiling. The wet-strong paper surface gypsum board of processing through fire prevention can be used for the room metope that humidity is larger, as the liner plate of the tilings such as toilet, kitchen, bathroom, metallic plate, plastic cover brick wall. Decorated gypsum board is taking plaster of Paris as primary raw material, and the multiple patterns that a small amount of fibrous material of admixture etc. is made, the sheet material of floriation, as gypsum printing plate, perforation ceiling board, gypsum embossed hung ceiling plate, Paper-faced gyp decorative lamination decoration board etc. It is a kind of novel house decorative material, is applicable to medium-to-high grade decoration, has lightweight, fire prevention, protection against the tide, easily processes, installs the features such as simple. Particularly new type resin profiling veneering water-proofing plasterboard plate face is coated with resin, facing profiling decorative pattern, and its tone pattern is true to nature, novel generous, timber intensity is high, anti-pollution, easy cleaning, can be used for decorated wall surface and does skirting and skirting board etc., is the ideal material that replaces lithotome and terrazzo.
Gypsum hollow lath is taking plaster of Paris as primary raw material, a kind of hollow plate processing after the appropriate light filler of admixture or fibrous material. This sheet material is paper using and binding agent not, when installation, without keel, is to develop than faster more a kind of light weight board. Be mainly used in interior wall and partition wall. Fibrous plaster is taking plaster of Paris as primary raw material, and the appropriate fibre reinforced materials of admixture is made. The bending strength of this sheet material, higher than Thistle board, can be used for interior wall and partition wall, also can replace timber to make furniture. Except traditional plasterboard, also have new product constantly to increase, as gypsum abatvoix, refractory slab, heat-insulating shield and gypsum composite board etc. The specification of plasterboard is also to high thickness, large scale future development.
