Abstract
The decorative thermosol plate is produced by using waste plastics, sawdust, stone powder and adhesive as material and through hot pressing. The present invention has no problem of free formaldehyde pollution during the production and use and can eliminate the environmental pollution caused by waste plastics, stone powder and other waste. The comprehensive waste utilizing technology has prospect of wide application in building and furniture.
Description
The invention belongs to building field, particularly relate to a kind of manufacturing process of decorative thermosol plate.
Be the decorative panel of bonding adhesive for a long time with the urea-formaldehyde glue, because production and practical process all have free formaldehyde to overflow, contaminated environment, infringement health, the development that a large amount of manpower and materials are devoted to low aldehyde adhesive is all dropped in countries in the world, all is not solved so far.In recent years along with the developing rapidly and the extensive use of plastic products in industrial or agricultural and daily life of plastics and processing of stone industry, outside the famine that increasing waste or used plastics goods and stone flour are abandoned, severe contamination environment, destroyed soil.
The objective of the invention is to disclose a kind of technology that adopts waste plastic to substitute Lauxite compacting decorative panel as hot melt adhesive, this technology had both thoroughly solved the long-term unsettled free formaldehyde environmental pollution problem of urea-formaldehyde glue plywood, eliminated the problem of environmental pollution that waste plastic goods and stone flour cause again, be a kind of comprehensive utilization, the environmental protection development technique that turns waste into wealth.
The manufacturing process of decorative thermosol plate made of waste plastics is: earlier waste polyethylene waste polypropylene thermoplastic waste plastic is broken into the fragment of diameter less than 5mm, then with wood chip and (or) stone flour mixes in the ratio of 1: 0.2～2 (weight ratios), after mixing with the additive of the tackifier powder and 0～5% (weight) of 0～10% (weight) again, deliver to that heating stirs into thick thing in 150～250 ℃ the thermal agitation machine, compression moulding in 150～250 ℃ of hot presses again, through the constant temperature pressurize after 3～5 minutes, the cooling, depanning the scleroid plate of certain specification.
Above-mentioned tackifier can be rosin, terpenes, and Petropols, polystyrene resin etc., wherein additive mainly is that the landing low melting viscosity prevents effects such as sizing material self-adhesion, can be paraffin, microwax, synthetic wax etc.
The present invention has following outstanding advantage: 1) replace urea-formaldehyde glue with the thermoplastic waste plastic, overcome volatile materials such as free aldehyde to the slow poisoning of human body and the public hazards of waste or used plastics and stone flour contaminated environment.2) added tackifier such as rosin, reduced the PUR melt viscosity and improved processing performance, made dry wood chip and stone flour and PUR wetting, the raising glue-joint strength.3) can select the waste or used plastics and the auxiliary agent of unlike material, it is water-fast that the decorative panel of compacting is had, oil resistant, acid and alkali-resistance and specific function such as fire-retardant.4) purposes is wide, but decorative thermosol plate made of waste plastics replacing wood plastic production furniture, door and window interior wall dividing plate, handicraft, packing is decorateed, and sound insulation, protection against the tide, the mothproof material that waits.5) cheap, profitable, the waste plastics PUR generally can adopt a large amount of discarded PE bags, mulch film etc., and cost is significantly less than phenolic resins, industrial chemicals such as Lauxite and curing compound.6) raw material sources are wide, and technology is simple, reduced investment, instant effect.
Decorative thermosol plate made of waste plastics is to utilize waste or used plastics for hot melt adhesive substitutes urea-formaldehyde resin adhesive, is kind of a highly effective fundamental measure of improving artificial panel technology processing workman's condition and environment for use.Having a wide range of applications aspect building materials and the furniture manufacturing industry.
Embodiment 1: 10 gram wood chips and 10 are restrained waste polyethylene membrane fragment mixings be placed in the beaker and stir evenly after 160 ℃ of following fusions, move in the tablet press machine and compress, placed 170 ℃ of following constant temperature 30 minutes, compress once more, again 170 ℃ of following constant temperature 5 minutes, the cooling depanning, diameter 40mm, the solid lump of thick 12mm.
Embodiment 2: with 1 gram rosin, 0.5 gram paraffin is smashed back and 5 gram wood chips respectively to pieces, and 5 gram stone flours mix; waste plastic film fragments with 5 grams stir evenly again, are placed in the beaker after 160 ℃ of following fusions, stir; move in the molding press and compress; placed 170 ℃ of baking oven constant temperature 30 minutes, and compressed, constant temperature is 5 minutes again; cooling; depanning, diameter 40mm, the solid lump of thick 9mm.
Embodiment 3: with 1 gram rosin, 0.5 gram paraffin is smashed the back respectively to pieces and is mixed with 20 gram stone flours, is tiled on the waste plastic film of 8 grams; rolling-in, Zhe becomes nahlock, is placed in the beaker to stir after 170 ℃ of following fusions; move in the molding press and compress; placed 170 ℃ of baking oven constant temperature 30 minutes, and compressed, constant temperature is 5 minutes again; cooling; depanning, diameter 40mm, the solid lump of thick 8mm.
