Abstract
The invention relates to a production process of a formaldehydeless three-layer solid-wood composite floor, which is formed by hot pressing or cold pressing a core board, a bottom board and a panel through an adhesive. The production process is characterized in that the adhesive comprises the following components by weight: the ratio of primary agent, filler and curing agent is 1:0.01-0.50:0.01-0.50. The production process is mainly and technically characterized in that by a formaldehydeless adhesive technology, no free formaldehyde releasing resource exists, so that a formaldehydeless three-layer solid-wood composite floor product is obtained. The performance index of the product conforms to the F***8 requirements of the international highest standard JAS233-2003 specifications for The Japanese agriculture standard of the common plywood, and the release amount of formaldehyde is less than 0.3mg/L.
Description
Technical field
The present invention relates to the production technology of furniture, the used formaldehydeless three-layer wood composite flooring of decoration industry.
Background technology
Along with the raising that people require indoor environment, the burst size of methanal in the wood-based plate more and more receives publicity, and research and development are efficient, the development that becomes the wood-based plate field of environmental friendliness and cheap bonding adhesive becomes.In recent years aspect scientific research and development, achieve notable results; Develop bonding adhesive such as low toxicity urea-formaldehyde glue, quick cured phenolic glue, artificial low pressure short period veneer resin, high-performance copolymer emulsion, furtherd investigate tannin glue, sulphite sol, cement, gypsum inorganic adhesive.When China's wood-based panel industry develops rapidly with the speed that exceeds national economy average growth rate number, also obtain corresponding growth as supporting with it bonding adhesive.
Calendar year 2001, China has worked out standard GB 18580-2001 " formaldehyde discharges and limits the quantity of in indoor decorating material---wood-based plate and the goods thereof ", and executes since on January 1st, 2002.But the existing market situation, the production people of veneer is main with three-aldehyde glue still, mainly comes from cost consideration, therefore, the burst size of methanal phenomenon that exceeds standard is more serious.Three-layer wood composite flooring is through the bonding adhesive hot pressing or the veneer of colding pressing and forming by central layer, base plate and panel; Adhesive is that formaldehyde main in the three-layer wood composite flooring discharges the source; Therefore, adhesive is selected the burst size of methanal of three-layer wood composite flooring product is played an important role.
Summary of the invention
Technical problem to be solved by this invention provides a kind of production technology of formaldehydeless three-layer wood composite flooring.
The production technology of environment friendly lumbercore plywood of the present invention; Be to pass through hot pressing or cold pressing through bonding adhesive by central layer, base plate and panel to form, it is characterized in that the weight of said bonding adhesive consists of: main glue: filler: curing compound=1: 0.01～0.50: 0.01～0.50.
Major technique characteristics of the present invention are through not containing the adhesive technology of formaldehyde, thoroughly stopping the release source of free formaldehyde, thereby obtain formaldehydeless core-board product.This product performance index meets the requirement of JAS233-2003 " JAS of common plywood " F ☆ ☆ ☆ ☆, and burst size of methanal is less than 0.3 mg/litre.
Mainly consisting of of bonding adhesive master glue of the present invention: polyvinyl alcohol; Polystyrene-acrylate; Polyvinyl acetate; butadiene-styrene rubber; water-soluble or water-dispersible polyester; polyethylene vinyl acetate resin, polyacrylate-vinylacetate, wherein any or also can be above-mentioned any several types compound.
The filler of bonding adhesive of the present invention mainly consists of flour, starch, precipitated calcium carbonate, powdered whiting; Ordinary calcium carbonate, calcium carbonate activated, kaolin, French chalk; Expansive soil, carbon black, white carbon, wherein any or also can be above-mentioned any several types compound.
The curing compound of bonding adhesive of the present invention mainly consists of polymeric multi isocyanate, water dispersible polyisocyanates, blocked polyisocyanate, aziridine, carbodiimides, epoxy silane one or more mixtures wherein.
As required, can in the aqueous systems of aqueous adhesive of the present invention, add additive and auxiliary agent commonly used.For example: hardener, pigment, dyestuff, antitack agent, dispersion stabilizer, viscosity modifier, levelling agent, anti-gelating agent, light stabilizer, antioxidant, ultra-violet absorber, plasticizing agent, sliding agent, antistatic agent, reinforcing agent, catalyzer etc.
The specific embodiment: following embodiment further specifies of the present invention, rather than limits scope of the present invention.
