Abstract
The present invention provides a wall body material which is formed by compounding a coating glass fiber reinforced cement plate and a polystyrene foam plastic plate by using proper binders. The coating glass fiber reinforced cement is prepared by using unique collosol-gel technology and has high alkali resistant performance. A fiber surface has a coating which is composed of a series of CaO, BaO, SiO2, TiO2, etc. The composite wall body material which is stuck by the coating glass fiber reinforced cement and the polystyrene foam plastic stick through the binders has the maximal advantages of low cost, simple technology, strong practicability and no pollution. The surface has the advantages of lightweight, high intensity, heat insulation, sound insulation, wear resistance and no combustion, and can be beautified by using various coating materials, and the surface indicatives obvious superiority for processing and inlaying type construction, assembly, etc. Moreover, the surface of the wall body can be drilled with holes and nailed with nails. Therefore, the material is a novel lightweight composite wall body material which has a development future and a prospect that the composite wall body material is easy to popularize and can be converted into products.
Description
Technical field
The present invention relates to a class coating glass fiber reinforced cement plate of material and the compound light wall material of polystyrene foam plastics.More particularly, the present invention relates to have the very coating glass fiber of high alkali resistance performance a kind of the preparation with sol-gel technology, with the cement that this coating glass fiber strengthens, reach this coating glass fiber reinforced cement and polystyrene foam plastics by the compound materials for wall of adhesive bonds.
Background technology
As everyone knows, the materials for wall that is used for nonweight-bearing member in daily life in a large number adopts some timber, metal alloy or macromolecule polymer material such as polymethyl methacrylate, ABS plastic etc. usually.For timber, mainly exist inflammable, intensity is low and the shortcoming of shock-resistant ability; Though non-combustion intensity of metal alloy height, cost is too high; Though and high molecular polymer can overcome above-mentioned shortcoming, intensity is low, and is not wear-resisting, and some lower-molecular substance that slowly discharges in long-term use is often poisonous, and human body is caused certain injury, does not meet modern requirements of green environmental protection.At above problem, make the development of construction material of novel practical environmental protection more and more come into one's own.
Glass fiber reinforced cement material (GRC) is to be reinforcing material with the glass fiber, with the cement mortar is a kind of composite material of base material, be the New Building Materials of early seventies exploitation, its goods overcome and improved cement concrete tensile strength low, allow that distortion is little, the shortcoming of impact resistance difference, have higher mechanical strength, be used widely in many fields such as buildings.But, in normal portland cement, adopt commercial silicate glass fiber no matter alkali-free, middle alkali or high alkali glass fibre as reinforcing material after, its intensity reduces greatly after being subjected to the corrosion function of cement matrix alkaline medium, wherein the most frequently used alkali-free glass fibre is in the green strength forfeiture 82～97% after a year of contact portland cement, the durability existing problems of GRC material.
This patent people begins successfully to develop BaO-TiO in the early 1990s
2-SiO
2On the basis that the ternary system coating is established, developed CaO-BaO-TiO again first according to erosion mechanism
2-SiO
2The quaternary system coating proposes the new approaches with The addition of C aO replacement BaO, scribbles a series of CaO-BaO-SiO by a large amount of experiments conclusive evidences
2-TiO
2Show excellent alkali resistant erosion performance Deng the coating glass fiber of forming, after the application of coatings glass fiber strengthened, GRC Mechanical Properties of Materials and durability obtained significantly to improve.
Successfully the development have on the basis of excellent mechanical performances and durable coating glass fiber reinforced cement material, the present invention is by combining GRC material and macromolecule polymer material, and the advantage that obtains a kind of GRC of collection material and macromolecule polymer material is lightweight, sound insulation, do not burn, wear-resisting high-quality composite type wall body mold material.
