Abstract
A heat-insulation fireproof sound-absorbing ecological gypsum board made of composite materials utilizes alpha-hemi-hydrated gypsum or beta-hemi-hydrated gypsum as a raw material, and is characterized by further utilizing gypsum whiskers and light materials (pearlite, glazed hollow beads or foam particles) as raw materials. The gypsum board is prepared by pouring, forming by rolling and drying mixed slurry of the three raw materials and water, and the gypsum board comprises, by weight, 20-80% of the alpha-hemi-hydrated gypsum or beta-hemi-hydrated gypsum, 10-65% of the gypsum whiskers and 5-20% of the light materials. The gypsum board can serve as a heat-insulation energy-saving board for an outer wall and an inner wall, a fireproof sound-absorbing tunnel board, a ceiling board and a decorative board, has the advantages of lightness, high strength, fine bending resistance and capability of reaching standards of a level-A fireproof ecological environment-friendly product, heat-insulation boards in different thickness can be produced according to heat-insulation and energy-saving requirements of different regions so as to meet the requirements on heat insulation and energy saving, and the fireproof heat-insulation boards in industrialized production are guaranteed to meet the requirements on energy saving and quality in installation and construction.
Description
Technical field
The present invention relates to the building decoration lagging material, concrete is a kind of light thermal-insulation plasterboard.
Background technology
In present building decorating industry, more and more stricter to the performance requriements of finishing material, especially the fire line of material, light silencing, moistureproofness, heat retaining property etc. are required increasingly highly, China advocates the exploitation inorganic materials as lagging material.Because these performances are directly connected to the safety of buildings, protection property and personnel safety all there is significance.Present most widely used have plastering and asbestos products, these two kinds of materials all have good fireproof heat insulating performance.But owing to the pollution of asbestos products to environment, its use range is more and more littler, receives strict restriction the most at last; Plastering has easy-formation, low cost and other advantages, but mainly exist than great; Be difficult for installing, moistureproofness is poor. and broken easily, do not reach shortcomings such as energy-conservation requirement.
The plasterboard of existing widespread use is the layer structure that gypsum adds paper, and fire resistance is bad, can only be used for indoor common decoration, can not be used for exterior-wall heat insulation.Also have a kind of its intensity difference of foaming plaster plate, heat insulation effect not good.
Summary of the invention
The purpose of this invention is to provide the ecological plasterboard of a kind of compound material insulated fire sound-absorbing, overcome existing plasterboard than great, be difficult for installing, moistureproofness is poor, and broken easily, heat insulation effect does not reach shortcomings such as building energy conservation requirement.
Technical scheme of the present invention is: the ecological plasterboard of a kind of compound material insulated fire sound-absorbing; Its raw material comprises alpha semi-hydrated gypsum or beta-type semi-hydrated gypsum, it is characterized in that: also comprise crystal whisker of gypsum and light material (perlite, glass bead or foam beads), with the water mixing mixed serum of three kinds of raw materials; Usefulness cast roll forming furnace drying method system; The weight ratio of three kinds of raw materials is: alpha semi-hydrated gypsum or beta-type semi-hydrated gypsum 20 ~ 80%, crystal whisker of gypsum 10 ~ 65%, light material 5 ~ 20%.
The ecological plasterboard of aforesaid compound material insulated fire sound-absorbing is characterized in that: alpha semi-hydrated gypsum or beta-type semi-hydrated gypsum 30 ~ 40%, crystal whisker of gypsum 50 ~ 60%, light material 10 ~ 15%.Because the accounting amount of crystal whisker of gypsum more than 50, makes the ecological plasterboard of compound material insulated fire sound-absorbing have best insulation, the sound damping performance.
The ecological plasterboard of aforesaid compound material insulated fire sound-absorbing is characterized in that: the multiple film in plate two sides, the material of the film of answering is an aluminium-foil paper.
Whisker be meant have the fixed shape of cross section, complete profile, perfect internal structure, length-to-diameter ratio be up to 5-1000 fibrous single crystal.Crystal whisker of gypsum of the present invention is meant the fibrous single crystal of half ability of swimming anhydrous calciumsulphate, is a kind of good insulation, sound absorbent material.
The ecological plasterboard of compound material insulated fire sound-absorbing of the present invention can be used as exterior wall, the energy-conservation plate of heat insulating inner wall; Its advantage is a lightweight; Intensity is good, and fracture resistance is good, reaches A level fire prevention ecological, environmental protective product standard; Can reach the requirement of energy-saving heat preserving according to the warming plate that different thickness is produced in different regional heat preservation energy-saving requirements, the fireproof heated board that this batch production is produced is secure to reaching energy-conservation specification of quality in installing and constructing.
