Abstract
The invention relates to a production process of a formaldehyde-free laminated wood board which is formed by a core plate, a middle plate and a surface plate through hot pressing and cold pressing with an adhesive. The production process is characterized in that: the adhesive comprises the components in parts by weight: 1 part of main agent, 0.01-0.50 part of filler and 0.01-0.50 part of curing agent. The production process disclosed by the invention has the main technical characteristic that: by adopting a formaldehyde-free adhesive technology and without a free formaldehyde release source, the formaldehyde-free laminated wood board product can be obtained. According to the production process disclosed by the invention, the product performance index of the formaldehyde-free laminated wood board product accords with the F (Four-Star) requirement of the international highest standard JAS232-2003 'Japanese Agricultural Standard of common plywood', and the formaldehyde release amount of the formaldehyde-free laminated wood board is less than 0.3mm/L.
Description
Technical field
The present invention relates to the production technology of furniture, the used formaldehydeless core-board 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 adhesive becomes.In recent years aspect scientific research and development, achieve notable results; Develop 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 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 glued board 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.Core-board be by central layer, middle plate and dash board through the adhesive hot pressing or the glued board of colding pressing and forming, central layer can be bonded by some little planks, the wooden quality of central layer is required relatively low, to reduce production costs.Middle plate is bonded on the two sides of central layer, and its thickness is thinner, and its wooden quality comprises that the decorative pattern requirement is generally than higher.The surface of plate during dash board is bonded in is the extremely thin wood layer of one deck.Central layer thickness is generally 9～44mm, and middle plate thickness is generally 1～5mm, and dash board (panel) is generally 0.1～2mm.
Summary of the invention
Technical problem to be solved by this invention provides a kind of production technology of formaldehydeless core-board.
The production technology of environment friendly lumbercore plywood of the present invention; Be to pass through hot pressing or cold pressing through adhesive by central layer, middle plate and dash board to form, it is characterized in that the weight of said adhesive consists of: main glue: filler: curing agent=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 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 adhesive of the present invention mainly consists of flour, starch, precipitated calcium carbonate, powdered whiting; Ordinary calcium carbonate, calcium carbonate activated, kaolin, talcum powder; Swelled ground, carbon black, white carbon, wherein any or also can be above-mentioned any several types compound.
The curing agent of 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: curing agent, pigment, dyestuff, antitack agent, dispersion stabilizer, viscosity modifier, levelling agent, anti-gelating agent, light stabilizer, antioxidant, ultra-violet absorber, plasticizer, lubricant, antistatic agent, reinforcing agent, catalyst etc.
