Abstract
The invention relates to immersion non-woven fabrics and a method for producing artificial boards by coating films on the immersion non-woven fabrics. The ration of the non-woven fabrics is between 50 and 500 g/m<2> and the thickness is between 0.5 and 5 mm; and a resin adhesive is a phenolic resin adhesive, a melamine resin adhesive or a polyurethane adhesive. The resin content of the immersion non-woven fabrics is between 28 and 36 percent, the volatile content is between 8 and 9 percent, and the pre-cure degree is between 30 and 55 percent. The method for producing the artificial boards by coating films on the immersion non-woven fabrics comprises the following steps: immersing the non-woven fabrics in the resin adhesive, and drying; and coating the films on the surfaces of the artificial boards through hot pressing, wherein the hot-pressing temperature is between 85 and 150 DEG C, the time is between 5 and 10 min, and the pressure is between 0.5 and 1 Mpa. The artificial boards produced by the method are wear-resistant, fire-retardant, neat, rich in color, low in cost, and environment-friendly.
Description
Technical field
The present invention relates to a kind of immersion non-woven fabrics, also relate to the method for utilizing this immersion non-woven fabrics producing artificial boards by coating films.
Background technology
Directly adopt the wood-based plate surface of log production not have texture, tone is single, can not meet the need of market.In order to show the pattern of abundant color and luster, novelty, improve the wood-based plate quality, veneer overlay, impregnated paper veneer Wood-based Panel Production technology have appearred in early 1980s, not only can decorate the wood-based plate outward appearance, and can improve physical and mechanical property, enlarge product purpose, improve wood-based plate use value.But, the quantity of the big footpath of natural high-quality level timber is constantly cut down, cause the not rich forest reserves to be on the verge of exhaustion, especially to the destruction of rare tree species.And use tame fast growing wood to replace veneer, limited the veneer timber value volume and range of product of making incrustation; Moreover breadth is little, the density many, various fast growing woods that scab are different because the thin plate of fast growing wood processing exists, the producing artificial boards by coating films that the impregnated paper veneer backing material plate is produced, and its plate face easily produces be full of cracks, peeling, covers phenomenons such as the mould pull-up falls.In order to protect natural rare tree resource, alleviate precious timber and supply with nervous situation, seeking a kind of novel mold materials that covers becomes the task of top priority.On the other hand, the nonwoven fabric (claiming Nonwovens English Non Woven by name again) that utilizes waste plastic, chemical fibre and string to make is environment-friendly materials of new generation, it is made of fiber orientation or at random, have physical and chemical performances such as protection against the tide, ventilative, pliable and tough, light weight, not combustion-supporting, easy decomposition, nontoxic nonirritant, recyclable regenerative utilization, and have abundant, the cheap characteristics of colour image.
Summary of the invention
In order to overcome the problem that prior art exists, the object of the invention comprises provides a kind of nonwoven fabric of producing through the resin glue dipping, and another purpose of the present invention provides a kind of manufacture method that adopts this immersion non-woven fabrics hot pressing producing artificial boards by coating films.
The present invention realizes in the following manner:
A kind of immersion non-woven fabrics of producing through the resin glue dipping, the quantitative of this nonwoven fabric is 50g～500g/m
2, thickness is 0.5mm～5mm; The resin glue of immersion non-woven fabrics is a kind of in phenolic resin glue, melamine resin adehsive or the polyurethane adhesive.
Described immersion non-woven fabrics after the resin glue impregnation process, its resin content are 28%～36%; Volatile content is 8%～9%; The precuring degree is 30%～55%.
A kind of manufacture method that adopts above-mentioned immersion non-woven fabrics producing artificial boards by coating films, concrete steps be with nonwoven fabric behind the resin glue impregnation drying, cover mould at the wood-based plate substrate surface through hot pressing, with strengthen the surface tensile strength.
The hot pressing temperature that described immersion non-woven fabrics covers mould is 85 ℃～150 ℃; Hot pressing time 5min～10min; Unit pressure 0.5Mpa～1Mpa.
What described wood-based plate substrate was bamboo oriented structure shaving board or wooden plywood or bamboo wood composite oriented structure glued board or fiberboard or building template with in glued board or container bottom board or the compartment board or the deck of boat is a kind of.
Cover template relatively with impregnated paper, use nonwoven fabric to substitute impregnated paper production and cover template, not only to cover template similar to impregnated paper, has the abundant decoration functions of surface color and polish, and nonwoven fabric covers comparatively equilibrium of mould surface temperature heat conduction, can overcome impregnated paper and cover the dried wet flower that the mould laminating machine causes because of temperature deviation and fluctuation, variable color, the bubbling product quality defect, and the fire retardant that adds in the synthetic resin of nonwoven fabric plays the fire protection flame retarding effect, and nonwoven fabric covers the crack that mould can be filled substrate surface, scab, prevent the surface checking of wood-based plate, peeling, cover quality problems such as the mould pull-up falls, particularly immersion non-woven fabrics covers the mould wood-based plate and can avoid the surface to cover the mould layering behind water logging bubble, come unstuck, collapse defectives such as limit, guarantee to cover the template product quality.In addition, nonwoven fabric mainly utilizes waste plastic, chemical fibre and string to make.Therefore, advantage of the present invention is smooth, rich color, wear-resisting, fire-retardant, with low cost and environmental friendliness.
The present invention further specifies by the following specific embodiment, but the present invention is not limited by cited embodiment.
The specific embodiment
