Abstract
The invention discloses a production process for a formaldehyde-free integrated finger joint laminated board. Core board strips are formed through hot pressing or cold pressing via an adhesive. The production process is characterized in that: the adhesive consists of a main agent, a filler and a curing agent in a weight ratio of 1:(0.01-0.50):(0.01-0.50). The production process has the main technical characteristics that: by a formaldehyde-free adhesive technology is adopted, and a free formaldehyde release source is absent, so that a formaldehyde-free integrated finger joint laminated board product is obtained. The performance indexes of the product meet the requirement of the highest international standard, F four star of JAS233-2003 Japanese Agricultural Standards for Ordinary Plywood; and the formaldehyde emission is less than 0.3 milligram/liter.
Description
Technical field
The present invention relates to the production technology of furniture, the used formaldehydeless integrated finger plate 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.The central layer that integrated finger plate is made up of little plank is through the adhesive hot pressing or the glued board of colding pressing and forming, and its typical binders is still for three-aldehyde glue is main at present, and people healthy caused certain harm.
Summary of the invention
Technical problem to be solved by this invention provides a kind of production technology of formaldehydeless integrated finger plate.
The production technology of the integrated finger plate of environment-friendly type of the present invention is to be passed through hot pressing or cold pressing through adhesive by central layer to form, and 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 integrated finger panel products.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.
