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.
