Abstract
The invention discloses a kind of fiberglass reinforced thermoplasticity concrete building brick supporting plate, supporting plate include by PP, PET, PVC, PU, glass fibre and other constitute mixture for use in production, the PP, PET, PVC, the mass fraction accounting of four kinds of components of glass fibre are:PP30 50%, PET5 25%, PVC0.5 20%, glass fibre 25 50%, the supporting plate are individual layer.120 280 DEG C of the compound melt temperature, the 30min of melting time 2.The 5MPa/m2 of briquetting pressure 0.5 of compound, the 10min of dwell time 0.5 after the melting.The 50min of semi-finished product supporting plate cool time 3 after the shaping.The more traditional Multi-layered bamboo gluing supporting plate of the present invention, the raw material of the supporting plate show as hydrophobicity, with prominent water resistance, efficiently solve the problems, such as that the bamboo glued supporting plate of conventional multilayer cannot be used because water suction causes sheet deformation;It is single layer structure to supporting plate of the present invention, and thoroughly the lamination defect that the bamboo glued supporting plate of conventional multilayer is produced in use is solved from structure;The 1.4g/cm3 of supporting plate density 1.1 of the present invention, with good surface abrasion resistance.
Description
Technical field
Patent of the present invention is related to supporting plate technical field, more particularly to a kind of fiberglass reinforced thermoplasticity concrete building brick support
Plate.
Background technology
China's building brick it is most commonly seen have solid clay brick and non-burning brick two kinds.Solid clay brick need high-temperature firing and
Into, according to statistics, the good farmland damaged every year by fired clay brick up to 700,000 mu, more than 7,000 ten thousand tons of quota of expenditure coal, generation it is a large amount of
Carbon dioxide and sulfur dioxide severe contamination is caused to environment.It is non-burning brick be using cement, flyash, cinder, gangue,
Mine tailings, residue of chemical industry, natural sand, tidal land mud etc.(One or several of above raw material)As primary raw material, it is not necessary to through high temperature
A kind of new material calcined and manufacture.Its excellent performance and the technique of environmental protection so that be widely used.It is non-burning brick to produce
During need to use supporting plate, the maximum traditional supporting plate of current occuping market share is two kinds of bamboo supporting plate and wooden supporting plate.
Both supporting plates all have the shortcomings that fragile, short life, cannot recycle.Its major defect is presented with:1)Above-mentioned supporting plate
All it is sandwich construction, monomer by adhesive hot binding together, ceaselessly shake by the wet environment of non-burning brick production and moment
Dynamic impact, easily causes the layering of multi-layered board;2)Bamboo, wooden is hydrophilic material, above-mentioned under dry, wet, hot environment
Constantly there is moisture absorption, solve wet circulation in supporting plate, cause supporting plate that buckling deformation occurs and brick cannot be met with the moisture of surrounding environment
Flatness requirement of the machine to supporting plate;3)Contain sand, stone particle for producing non-burning brick raw material, be positioned over non-burning brick on supporting plate
A large amount of frictions are produced in transport, stacking.It is poor that relatively low bamboo, the wooden supporting plate of density of material shows wearability.Additionally, market
Also there are minimal amount of PVC supporting plates and steel supporting plate.But the former poor toughness, is easily broken;The latter's steel supporting plate gets rusty easily, therefore does not all have
It is widely used.
Supporting plate directly affects the production cost of brickmaking as the easily-consumed products in non-burning brick manufacturing process.It is how effective
Above-mentioned defect is solved, the important problem that supporting plate industry faces is had become.
The content of the invention
The present invention is directed to deficiency of the prior art, there is provided one kind has preferable intensity, and is unlikely to deform the glass for getting rusty
Fibre enhancing thermoplasticity concrete building brick supporting plate.
In order to solve the above-mentioned technical problem, the present invention is addressed by following technical proposals:A kind of fiberglass reinforced thermoplastic
Property concrete building brick supporting plate, including the individual layer supporting plate that PP, PET, PVC, glass fibre are mixed to prepare is each in the individual layer supporting plate
Component has following mass ratio:PP is that 30-50%, PET are that 5-25%, PVC are 0-20%, glass fibre 25-50%.
In such scheme, it is preferred that the PP, PET, PVC, the compound of glass fibre obtain melting mixing by heating
Material, 120-280 DEG C of melt temperature, melting time 2-30min.
In such scheme, it is preferred that melt-mixed material is obtained semi-finished product supporting plate, briquetting pressure 5- through press and mould molding
15MPa, dwell time 0.5-10min.
In such scheme, it is preferred that the semi-finished product supporting plate is finally obtained individual layer supporting plate, cool time through cooling and shaping
3-50min。
In such scheme, it is preferred that the glass fibre length 1-20mm.
Compared with prior art, the following beneficial effect of base of the present invention friend, by using hydrophobicity raw material, choose PP,
PET, PVC, glass fibre are main characteristic component, and the flowing of complex optimum raw material, toughness and strength character, are made density
1.1-1.4g/cm3Single layer structure supporting plate, it is comprehensive effectively to solve existing supporting plate water suction, layering, deformation, not wear-resisting, easily broken
The shortcoming split, easily got rusty.
