Abstract
The invention discloses a formaldehyde-free environment-friendly glass fiber gypsum composite material comprising the components of, by weight: 500-1500 parts of hemihydrate gypsum powder, 20-50 parts of glass fiber with a length of 800mm, 600-800 parts of water, 30-50 parts of a biomass adhesive, and 0.5-2 parts of a foaming agent. The formula is reasonable. During gypsum decorative plate manufacturing, the cost is low, and production process is simple. The prepared gypsum decorative plate has excellent physical performances such as high strength, high tensile strength, good water resistance, and the like. On the basis of maintained good performances of light weight, sound insulation, and the like, the material is anti-moth and green.
Description
Technical field
The present invention relates to a kind of glass fibre composite gypsum material, be specifically related to a kind of formaldehydeless environmental-friendly glass fiber composite gypsum material, the invention still further relates to the application of this matrix material.
Background technology
China is the production and consumption big country of timber and woodwork in the world, is also the minimum countries of the per capita forest reserves simultaneously.Timber consumers demand in nearly ten years rapidly increases with the speed of 1000 ten thousand steres every year on average, estimates that timber demand in 2015 reaches 4.6 billion cubic meters, and breach is 1.7 billion cubic meters.From above data, make full use of logging residue, industrial wood waste and inferior timber development wood-based plate and timber and glued joint goods, be to solve the be becoming increasingly acute effective measure of contradiction of timber supply and demand.And that wood adhesive plays a part in these measures is very important, demand is also just increasing.
Gypsum is widely used in building materials industry, the light gypsum sheet material that the semi-hydrated gypsum of particularly take is made as main raw material, gypsum block, brushing gypsum etc.Plasterboard has light weight, does not fire, heat-insulation and heat-preservation, sound absorption, the performance such as can saw, can follow closely.The production energy consumption of plasterboard is low, it is little, with short production cycle to invest, and is a kind of more satisfactory interior wall and ceiling decoration material.
At present, plasterboard is mainly used synthetic macromolecule adhesive, and synthetic macromolecule glue mainly comprises " three aldehyde " serial tackiness agent, polyvinyl acetate glue stick and acrylic emulsion tackiness agent.But, along with the scarcity day by day of petroleum resources and the enhancing of people's environmental consciousness, utilize inexhaustible, nexhaustible renewable resources to produce the wood adhesive with the feature of environmental protection, become a kind of inevitable development trend.
Summary of the invention
Technical problem to be solved by this invention is to provide that a kind of preparation technology is simple, the formaldehydeless environment-protective glass fibre composite gypsum material of low production cost.
The present invention also provides the application of this matrix material in decorative board for wall.
For solving the problems of the technologies described above, the technical scheme that Bian of the present invention uses is:
An environmental-friendly glass fiber composite gypsum material, described matrix material comprises the component of following weight part:

Above-mentioned whipping agent is preferably AC whipping agent.
For the cohesive force between consumption, increase glass fibre and the gypsum hardenite of minimizing glass fibre, above-mentioned glass fibre process water-soluble epoxy resin, polyvinyl acetate emulsion or propylene glycol routinely treatment process carries out surface treatment.
The compound method of above-mentioned biomass adhesive comprises the following steps:
(1) starch milk W-Gum acid hydrolysis oxidative: the hydrochloric acid of W-Gum and 0.5mol/L is mixed with to 20～40%(W/W), pack in flask, the ammonium persulphate that adds starch butt 1.8% (w/w), under 60 ℃ of water bath condition after acidolysis 1h, adjusting pH is 4.0, is warmed up to 70 ℃ and keeps 45min;
(2) graft copolymerization: the mix monomer that adds starch butt 80% (w/w), in mix monomer, the volume ratio of vinyl acetate and butyl acrylate is (20～30): (10～20), regulate that pH is 2.5, temperature is 75 ℃, it is 3h that mix monomer drips the time length, and after graft reaction 1.5h, adding the ammonium persulphate of starch butt 0.45% (w/w), the whole graft reaction time is 3.5h;
(3) make biomass adhesive after adding urea to mix.
The present invention also provides the application of a kind of formaldehydeless environmental-friendly glass fiber composite gypsum material in decorative board for wall, and the preparation process of decorative board for wall comprises the following steps:
(1) batching: quantitative semi-hydrated gypsum powder, glass fibre, water are put into stirrer, and the powder in stirrer and water are for intermittently add simultaneously.
(2) moulding: Bian forming machine.
(3) dry: Bian intermittent type tunnel furnace, steam passes through sidewall heat exchanger, and transverse convection flow heating drying, decorative sheet are parallel with air flow line.
(4) dried plasterboard is through check, and packing is put in storage.
Compared with prior art, beneficial effect of the present invention is:
The present invention fills a prescription rationally, uses starch biomass adhesive, has not only reduced the release of formaldehyde, and can increase the cohesive force of glass fibre and gypsum hardenite; Low production cost, the production technique of gypsum adorned board are simple, the gypsum adorned board of preparation not only has the good physical propertys such as intensity is high, tensile strength is high, water resistance is good, and keeping, under the prerequisite of the premium propertiess such as lightweight, sound insulation, having possessed the performances such as Anti-moth-eating, environmental protection.
