Abstract
The present invention provides a light partition board made of cement and polyphenyl foam material. Said partition board is characterized by containing low-alkali cement as agglomerating material, polystyrene foam plastics as filling material and alkali-proof glass fiber coated mesh fabric as reinforcing material. Said invented product is light in weight, high in strength, heat-insulating, sound-insulating, fire-proof, water-resistant, anti-freezing and anticorrosive, etc..
Description
What the present invention relates to is a kind of partition board, particularly be a kind of light partition board made of cement polyphenyl foam.
Along with the continuous development of builing industry, highrise building is increasing.Variously can alleviate buildings deadweights, reduce beam column amount of reinforcement and construction costs, improve the indoor area that utilizes, the multi-functional composite wall body material of lightweight that has comprehensive functions such as heat insulation, sound insulation, water-fast, fire prevention again is favourably welcome.At present, China can be used as or is a lot of through the Light trabs of compound formation materials for wall, as gypsum plank series, and fiber cement board series, calcium silicate board with microporous, vegetable fibre board series, GRC round-hole partition wall board, steel wire net rack cement filled board, the sandwich composite plate of color steel etc.What development was very fast in recent years is representative with steel wire net rack cement filled board, color steel filled board and GRC round-hole partition wall board mainly.These light wall board materials all have superiority in many aspects.Can not to satisfy the requirement or the cost of modern high-rise building too high but exist bulk density, deformation, intensity, water resistance, fire line, corrosion resistance or durability aspect.Poor water resistance as the gypsum lumber; Magnesite matter wallboard is eliminated with bent distortion because of the serious halogen that returns; String scutum corrosion-resistant is subject to damage by worms, damaged by rats; Though color sandwich composite plate of steel and calcium silicate board with microporous feature performance benefit are many, cost is too high, and (the sandwich composite plate price of common color steel is at 255 yuan/m
2About); The comprehensive cost of steel wire net rack cement filled board (Qin Bai plate, 3D plate etc.) also up to 155 yuan/
2M, and contain relatively large foamed plastics, its fire-resistant fire line is poor, also can discharge a large amount of suffocative toxic gases when meeting fire, and GRC round-hole partition wall board cost is lower, but long-term deformation is slightly little, and the seam part is prone to the crack.
In view of above reason, the objective of the invention is for provide a kind of light weight, high strength, heat insulation, sound insulation, fire prevention, water-fast, freeze proof, anticorrosion, deformation is little, safe, can organize arbitrarily every light partition board made of cement polyphenyl foam.
Have in the partition board of the present invention the cementitious material done low alkali cement, do inserts polystyrene foam plastics, make the alkaline-resisting band made of plastics-coated glass fibre grid cloth of reinforcing material, foamed plastics can adopt waste polystyrene foam plastic, reduces cost.
Above-mentioned low alkali cement is quick hardening sulphoaluminate cement.
The incorporation of above-mentioned polystyrene foam plastics is 0.2～5.0% of a low alkali cement weight, and optimal mixing amount is 2.0%.
The present invention is cementitious material with the low alkali cement, and polystyrene foam plastics is an inserts, and alkali proof fiber plastic-coated grid cloth is a reinforcing material, makes by cooperating, stir, pour into a mould, vibrate, take out series of process such as the heart, facing, maintenance.Through body of wall tail surface quality of materials supervision and inspection station, Sichuan Province, national fireproof building material quality supervision and test test center and southwest building institute verification test, its moisture content, water absorption rate etc. all reach national standard (referring to Fig. 1) light weight, intensity height, heat insulation, sound insulation, fire prevention, water-fast, freeze proof, anticorrosion, deformation is little, safety, production small investment, cost of production is low (≤32 yuan/m
2), can eliminate the city " white pollution (waste foam plastics accumulation) promotes environmental protection (to produce 20000 m per year
2Wallboard can consume the about 1000m of plastic waste foam
3), can saw and can dig, can according to requirement of engineering arbitrarily group every, in the building site easy for installation fast, just can carry out incrustation (coat, wallpapering work wall paper, tile fixing or other surfacing, can satisfy modern architecture materials for wall already and require) as long as handle through simple trench seam.
Introduce embodiments of the invention below:
Fig. 1 is the profile schematic diagram of Light trabs of the present invention.
Fig. 2 is the schematic cross-sectional view of Light trabs of the present invention.
Referring to Fig. 1, Fig. 2, shape of the present invention and existing GRC round-hole partition wall board are similar.The present invention is to be cementitious material with the quick hardening sulphoaluminate cement, waste polystyrene foam plastic is inserts (its volume be cement weight 2.0%), alkaline-resisting band made of plastics-coated glass fibre grid cloth is a reinforcing material, makes the novel light round-hole partition wall board by cooperating, stir, pour into a mould, vibrate, take out series of process such as the heart, facing, maintenance.
Long L=0～the 4500mm of plate of the present invention, the wide B=600mm of plate, thickness of slab H=60～100mm, its tongue and groove shape (as square, circle etc.) and hollow hole heart size can require do corresponding change (referring to table 2) according to service condition with quantity.
