Abstract

The artificial board with plastic surfaces is made up through spreading film and glass fibre cloth, scraping applying mixed material, sticking decorative sheet, painting, covering film, rolling, removing film and removing excess material, and features resisting fire, water, moisture, acid, alkali and ageing, high elasticity and tension strength, no deformation, uniform thickness, and appearance like plastic face.

Description

Artificial plywood with plastic surface

The present invention relates to a kind of sheet for architectural decoration, specifically a kind of artificial plywood with plastic surface with overall characteristics such as super quality and competitive price, water proof fire retardants.

Along with improving constantly of living standards of the people, the increase of income, indoor and outdoor decoration has become people's consumption hot spot, and day by day to medium-to-high grade development, the plastic-faced plywood of luxurious elegance enjoys favor, the plastic-faced plywood of Xiao Shouing is divided into two kinds of pure wooden plastic-faced plywood and chemically composited plastic-faced plywoods in the market, wooden plastic-faced plywood price is high, inflammable water funk, though chemically composited plastic-faced plywood price is lower, but because it is with magnesia, magnesium chloride, sawdust is that primary raw material is made, because of having used magnesia, product surface is often analysed and is appeared white powder formation " returning white ", magnesium chloride, a large amount of moisture content around sawdust can absorb, product " is got damp ", " return halogen ", " rake angle distortion ", thus bring shade for the development prospect of product.

Purpose of the present invention will provide a kind of the above two defectives of can overcoming, the novel artificial plywood with plastic surface of super quality and competitive price, water proof fire retardant exactly.

The object of the present invention is achieved like this: artificial plywood with plastic surface has thoroughly changed the convention with magnesium chloride, magnesia and sawdust production composite plate, and does skeleton with glass fabric, and as filler, several industrial chemicals of easily purchasing are composited with talcum powder.Its main processes is: horizontal mylar → shop glass fabric → blade coating mix → applying polywood paper → upper glass steel lacquer → covered with polyester film → roll-in → take off mylar → wipe out four limit gummosis → finished products.Mix wherein is by unsaturated polyester resin, claim unsaturated-resin, talcum powder, curing agent, promoter formulated again, its proportioning weight ratio is a unsaturated-resin: talcum powder: curing agent: promoter=45%～48%: 45%～48%: 3～6%: 0.5～5%.Wherein fiberglass lacquer is formulated by unsaturated polyester resin, curing agent, promoter, and its proportioning weight ratio is a unsaturated polyester resin: curing agent: promoter=90～96%: 3～6%: 0.5～5%.Can carry out at normal temperatures and pressures for the whole process of production that makes product, curing agent is selected the normal temperature type curing agent for use, and as cyclohexanone peroxide, simultaneously, promoter is selected the promoter that is used with curing agent for use, as cobalt naphthenate.Curing agent with can produce the free radical chemically reactive after unsaturated-resin combines and make resin solidification; The function of promoter is to make resin shorten cure cycle, improves reacting to each other of peroxide.

Unsaturated polyester resin, also making unsaturated-resin be dissolved in vinyl monomer (often being styrene) by the condensation polymer of unsaturated polyol and dihydroxylic alcohols usually makes and forms, it be called fiberglass after fiber glass packing combines, have the intensity height, premium properties such as proportion is little, hardness is high, good luster, heat-resisting water-fast, oil resistant, acid and alkali-resistance, under the effect of chemical reagent, normal temperature, normal pressure, be solidified into and mould.Because this characteristic, make with the glass fabric is skeleton, with unsaturated-resin etc. is that the product of the present invention of batching has had good physical and chemical properties, fire-retardant, waterproof, corrosion-resistant, insulation, anti-aging, elasticity, quiet song and plane tensile strength all are better than plurality of advantages such as any wooden and chemically composited layered board; In addition product of the present invention have outward appearance like plastic facing, as bright as a sixpence, thickness evenly, can be curled into tube, crookedly use advantages such as indeformable.

Embodiment:

1) mylar of tightening with iron frame (size is bigger 10 centimeters than every of finished product for every) is lain in (elder generation shop sponge is put one three again and closes piece on the workbench) on the workbench;

2) layer overlay glass fabric (size be every bigger 5 centimeters) entirely on mylar than every of finished product;

3) take by weighing 191 resins in container, add the technical grade talcum powder of same weight, fully stir evenly, add cyclohexanone peroxide, consumption is 3% of an amount of resin, fully stirs evenly, and adds cobalt naphthenate, and consumption is 3% of an amount of resin, fully stirs evenly, and makes batching;

4) half of the material that will prepare apace with scraper plate is coated with equably and scrapes on glass cloth, and the marginal portion all will scrape, and repaves last layer glass cloth behind the drawout, more remaining material is all scraped equably on glass cloth;

5) polywood paper that shears entirely is attached on the glass cloth of scraping honest material;

6) get half 191 resins of front amount of resin, add curing agent, promoter, make the fiberglass lacquer after stirring and be poured on the horizontal edge of polywood paper by aforementioned ratio;

7) cover one deck mylar (the same with bottom film big), evenly roll at full tilt, the fiberglass lacquer is coated on the paper equably, do not stay bubble, be bonded together with mylar with roller;

8) can take off film about half an hour, take off top film earlier, take the film of face again off;

9) with scissors have one's hair trimmed four limit gummosis certified products, vertically-arranged or volume are put and all can.

Claims

1, a kind of artificial plywood with plastic surface, it is characterized in that main processes is: horizontal mylar → shop glass fabric → blade coating mix → applying polywood paper → upper glass steel lacquer → covered with polyester film → roll-in → take off mylar → wipe out four limit gummosis → finished products, mix wherein is formulated by unsaturated polyester resin, talcum powder, curing agent, promoter, and its weight proportion is: unsaturated polyester resin: talcum powder: curing agent: promoter=45～48%: 45～48%: 3～6%: 0.5～5%.

2, artificial plywood with plastic surface according to claim 1, it is characterized in that described fiberglass lacquer is formulated by unsaturated polyester resin, curing agent, promoter, its weight proportion is: unsaturated polyester resin: curing agent: promoter=90～96%: 3～6%: 0.5～5%.

3, artificial plywood with plastic surface according to claim 1 and 2 is characterized in that described unsaturated polyester resin selects 191 resins for use; Curing agent is selected cyclohexanone peroxide for use; Promoter is selected cobalt naphthenate for use.
