Description

3 D weaving hollow fabric enhanced foaming cement heat preserving plate and preparation method thereof

Technical field

The present invention relates to a kind of fiber mesh reinforced foam cement heat preserving plate, particularly relate to a kind of 3 D weaving hollow fabric enhanced foaming cement heat preserving plate, there is the foam cement of good thermal insulation, insulation, sound insulation, the performance such as high-strength, belong to building material field.

Background technology

At present, the kind of the wall thermal insulating lagging material that China is common mainly contains: porous plastics, inorganic silicic acid salt lagging material, light thermal-insulating fragment of brick etc., according to the achievement in research of domestic and international lagging material to the performance requirement of Modern New building to material of construction, desirable materials for wall can be summarized, there is good insulation, heat insulation, every sound performance, good fire line, flame retardant resistance, sex change coefficient is little, resistance to deterioration is good, weather resistance is high, stable performance, construction is simple, with low cost, meet the requirement of energy-conserving and environment-protective simultaneously, in production and construction process, disadvantageous effect is not caused to human body and environment, and can carry out and circulate in utilization, but existing material technology can not meet the demand.This just triggers the birth of foam cement, foam cement manufactures thermal insulation layer, for roof heat insulation and exterior-wall heat insulation, substitute other lagging materials such as polystyrene (benzene plate) porous plastics, there is the adhesion property of unrivaled heat-insulating property and structural sheet, when also having convenient construction, environmental protection, joint, the various advantages such as synergy.

As inorganic heat insulation material, there is two problems under foam cement natural curing state: one is a large amount of existence due to hole, causes foamed cement intensity not high, the phenomenon such as often rupture in production, transport, construction and the link such as use, damaged; Two is cause foaming uneven because the cement solidification time is long, and hole caves in seriously, causes heat-insulating property to decline.Domestic many enterprises adopt three dimensional fabric strongthener, domestic patent (00135845.6) mention using hollow layer connecting fabric as skeleton, through soaking with resin, curing molding, is mainly used for resin tooth material, and domestic patent (200610038306.1) describes a kind of three dimensional woven fabrics, adopt special high-performance fiber, with different weaving process, reinforced composite framework characteristic, between two-layer panel, vertical support is good.Domestic patent (CN 202882222 U) is mentioned using fiber stereoscopic grid as skeleton, filling concrete material is carried out wherein in hollow structure, for alternative traditional reinforcing bar, concrete material is strengthened, but this scheme cannot solve the problem that cement solidification time long hair abscess hole caves in.My company 09 year patent (CN200920038138.5) by microwave maintenance equipment, maintenance is carried out to cement products, but cannot strength problem be solved.

Summary of the invention

The present invention is directed to above-mentioned weak point, foam cement is foamed at three dimension stereo fabric situ, because three-dimensional hollow stereo fabric has exceptionally straight connection warp, therefore greatly strengthen the anti-pressure ability of foamed cement, simultaneously with microwave equipment rapid curing, realize foaming hole even, avoid caving in, possess high-strength heat preservation flameproof effect.

The object of the invention is achieved by the following technical programs:

3 D weaving hollow fabric enhanced foaming cement heat preserving plate, comprise the 3 D weaving hollow fabric of coated foam cement, described 3 D weaving stereoscopic mesh reinforcing fabric, fabric is by surface layer, backing layer, and rigid fiber wire surface layer and backing layer coupled together in addition is integrally weaved or woven and forms.Described surface layer and backing layer fiber preferentially adopt tubular fibre to carry out the braiding of surface layer and backing layer, form grid clearly, and from upper and lower surfaces filling-foam cement;

The fiber that described surface layer and backing layer adopt includes but not limited to the one in the fibers such as polyamide fibre, polypropylene fibre, polyvinyl, polysulfones, polyester, polymeric amide, carbon fiber, glass fibre, basalt fibre;
