Description
Technical field
The present invention relates to a kind of production method of decorative panel, belong to construction material fabricating technology field, particularly relate to a kind of production method of high-strength high-voltage decorative panel.
Background technology
At present, the indoor hardware fitting of China mainly contains paint, coating, soft decoration material wallpaper, wall paper and decorative panel.Paint contains volatile organic contaminant matter mostly, to using or occupant's healthy meeting causes to a certain degree potential hazard.That wallpaper, wall paper etc. exist is non-watertight, non-moistureproof, easily come off during high humidity, the easy shortcoming such as mouldy, and used glue mostly is greatly the benzole soln of rubber-like adhesive during stickup, and volatile solvent is harmful equally.Decorative panel is material mainly with timber or timber derivative greatly, through being pasted on the base material behind the paint finishing.
Present widely used high pressure laminated decorative board is to produce by HTHP with stationery (comprise and decorate facial tissue and basic paper) heat of immersion thermosetting resin, be mainly used in furniture and interior decoration, in a great variety, surface treatment also has the various ways such as Gao Guang, inferior light, relief surface, because resin content is high and the employing high-temperature high-pressure craft, surface compact, thus water-fast, dry heat resistance, corrosion-resistant, impact resistance good.
Domestic production enterprise adopts part Lauxite, modified urea-formaldehyde resin to substitute higher melamine resin, the phenolic resins of production cost mostly, uses recycled writing paper as the alternative price of core paper is higher but the wood pulp paper that intensity is high.Because facile hydrolysis, pyrolysis after Lauxite solidifies, its tensile strength of high-pressure decorating plate of making as the core paper of high-pressure decorating plate with Lauxite dipping recycled writing paper is lower, easy cracking when humidity or variations in temperature are larger in the compound rear use of base material, during such as processing such as need perforate, perforatings in using, be prone to cracked.
Little (receiving) rice cellulose reinforcing agent is the suspension that adopts fibrous raw material (such as pure wood pulp paddle board) to make by the high-shear homogenizer homogeneous 60～70 ℃ of processing through (sulfuric acid) acidifying, the surface contains great amount of hydroxy group, can be combined with the paper fibre compact, be hot pressed into the tensile strength of plate behind the Effective Raise recycled writing paper impregnating resin.Because little (receiving) rice cellulose is suspended state in water, run-of-the-mill concentration is low by 3～5%, runs off as adding at paper-making process easily with copying in the paper loss of water.
