Abstract
A high-filler antibacterial and antimildew veneer is proportionally prepared from wollastonite powder, vinyl chloride-vinyl acetate copolymer resin, vinyltriethoxy silane, amide oleate, antibacterial agent, antimildew agent, tin methylmercaptide, and titanium white powder through coupling, dispersing, mixing banburying, extruding out and calendering.
Description
Technical field
The present invention relates to the preparation method of thick china, a kind of specifically preparation method of thick china of high filling antibacterial and mouldproof.
Background technology
Raising day by day along with living standards of the people, people constantly follow the fashion on decoration material, attractive in appearance, graceful, environmental protection, various thick chinas arise at the historic moment, development rapidly, slicing wood thick china, paper overlay plate, plastic veneer, metal foil overlay plate etc. have appearred in succession, on furniture, cabinet, door-plate, windowsill, desktop, table top, fit widely and use, interior decoration is taken on an entirely new look, increased aesthetic feeling and class.Yet, the relevant personnel detect using thick china surface after one month to carry out sanitation performance, find that above-mentioned four kinds of thick china surfaces all grow to some extent and breeding pathogenic bacteria such as staphylococcus aureus, Escherichia coli and black-koji mould, green pus mould, saccharomycete etc., thick china surface in particular for dining table, computer desk, chess and card table, desk, toilet door-plate, kitchen cabinet, pathogenic bacteria and mould more, directly influence the healthy of people, cause the generation and the infection of some diseases.For this reason, how to improve the antibacterial and antimildew function of thick china, improve the hygiene and health condition of people's live and work environment, caused researcher's concern.
In recent years, more domestic unit exploitation antibacterial antimildew surface decorative material and usings method thereof, with macromolecule resin, antiseptic, wearability filler etc. is raw material, adopt mixing, impregnation technology to coat decorated body (sheet material) surface, and carry out surface cure and handle, the preparation antibacterial antimildew surface decorative material.The ornament materials of this method preparation, use initial stage face coat adhesive property and antibacterial and mouldproof are functional, after using a period of time, because coating material is different with the shrinkage factor and the coefficient of expansion of sheet material (timber, plastics, metal), add inevitably friction and collision in the use, antibacterial surface fungus resistant coating material easily taking place come off, influence its antibacterial and mouldproof performance, and the antibiotic life-span is shorter.Retrieve a large amount of patent documentations and the research paper of publishing, do not find that as yet with wollastonite in powder and vinyl chloride-vinyl acetate copolymer resins be base stock, add VTES, antiseptic, mould inhibitor, Methyl stannum mercaptide etc., the relevant report of adopt coupling, dispersion, blend, banburying, extrude, calendering technology preparation height being filled the thick china of antibacterial and mouldproof.
Summary of the invention
The defective that exists for the thick china that overcomes present domestic use, the invention provides a kind of preparation method of thick china of high filling antibacterial and mouldproof, it is characterized in that: with wollastonite in powder and vinyl chloride-vinyl acetate copolymer resins is base stock, add VTES, oleamide, antiseptic, mould inhibitor, Methyl stannum mercaptide, titanium dioxide, through coupling, dispersion, blend, banburying, extrude, calendering technology processes.The thick china of this method preparation, can suppress Escherichia coli, staphylococcus aureus, black-koji mould, green dense mould effectively, saccharomyceticly grow and breed, the antibacterial and mouldproof persistence is good, and have characteristics such as excellent fire retardant, waterproof, corrosion-resistant, rub resistance, shock resistance, be applicable to that the veneer of desktop, cabinet, door-plate, furniture is decorated.
For realizing that the technical scheme that the object of the invention adopted is:
Material particle size is 800～1000 purpose wollastonites in powder, contains the vinyl chloride-vinyl acetate copolymer resins of 12.5～17.0% vinyl acetates, VTES, oleamide, antiseptic, mould inhibitor, Methyl stannum mercaptide, titanium dioxide;
73～81 parts of prescription (weight portion) wollastonites in powder, 12～20 parts in vinyl chloride-vinyl acetate copolymer resins, 1.0～1.8 parts of VTESs, 1.2～2.0 parts of oleamides, 1.4～2.4 parts of antiseptics, 0.5～1.0 part of mould inhibitor, 0.4～0.8 part of Methyl stannum mercaptide, 1.5～2.5 parts of titanium dioxides;
The preparation method places the high speed kneader with wollastonite in powder, control rotating speed 500r/min, and 105 ± 2 ℃ of temperature behind the kneading 20min, add VTES, coupling processing 10min; Add oleamide again, control rotating speed 500r/min, 102 ± 2 ℃ of temperature, dispersion treatment 8min; Add vinyl chloride-vinyl acetate copolymer resin, antiseptic, mould inhibitor, Methyl stannum mercaptide, titanium dioxide successively, control rotating speed 250r/min, 95 ± 2 ℃ of temperature, blend 12min; Place the adding pressure type banbury, 165 ± 2 ℃ of control banbury temperature, banburying 15min; Place double screw extruder, control extruder barrel temperature: 170～175 ℃ in I district, 175～180 ℃ in II district, 183～188 ℃ in III district, 188～192 ℃ in IV district, 185～190 ℃ in V district, 185～188 ℃ of die heads plastify and extrude; Through the calender calendering, 192～196 ℃ of control rolling mill roller temperature are pressed into the thick china that thickness is 0.8～1.5mm again.
Antiseptic of the present invention is that 5.8% carry zinc basic zirconium phosphate and purity are that 99.5% cerium oxide mixes by 1: 0.4～0.8 part by weight and forms by zinc content.
Mould inhibitor of the present invention is 98.5% tributyl tin fluoride by purity with purity is that 99.0% pentachlorophenol mixes by 1: 0.5～0.9 part by weight and forms.
The invention has the beneficial effects as follows: 1. adopting VTES is coupling agent, oleamide is a dispersant, wollastonite in powder is carried out coupling processing and dispersion treatment, make the wollastonite in powder surface become lipophile by hydrophily, strengthen the compatibility and the adhesion of wollastonite in powder and vinyl chloride-vinyl acetate copolymer resins, increased substantially the loading of wollastonite in powder; 2. adopt year zinc basic zirconium phosphate and cerium oxide to be mixed into antiseptic, improved the dispersing uniformity and the antibacterial bacteriostatic rate of year zinc basic zirconium phosphate in thick china; 3. adopt tributyl tin fluoride and pentachlorophenol to be mixed into mould inhibitor, make full use of the cooperative effect of two kinds of mould inhibitors, improved the mildew-resistant broad spectrum activity and the anti-mold effect of thick china; 4. the thick china that utilizes the present invention to make, can suppress Escherichia coli, staphylococcus aureus, black-koji mould, green pus mould effectively, saccharomyceticly grow and breed, the antibacterial and mouldproof persistence is good, and have characteristics such as excellent fire retardant, waterproof, corrosion-resistant, rub resistance, shock resistance, be applicable to that the veneer of desktop, cabinet, door-plate, furniture is decorated.
