Abstract
The invention relates to a method for enhancing a paperless membrane-coated artificial board by micro/nano fibrils, which mainly comprises the following process steps: using wood pulp as a raw material, and preparing a micro/nano fibril material with an ultrasonic cell disruption apparatus; mixing micro/nano fibril dispersion solution and water-soluble phenolic (or melamine) resin; coating the well mixed solution of the micro/nano fibrils and the resin on the surface of a prepared artificial board (such as a plywood, a fiberboard or a particleboard) substrate; aging the artificial board with the surface coated with the mixed solution of the micro/nano fibrils and the resin, and feeding the artificial board into a hot press for hot pressing; and naturally cooling and stacking the membrane-coated artificial board after being hot-pressed. The invention has the advantages that: the mixed solution of the micro/nano fibrils and the resin is coated on the surface of the artificial board, and the artificial board is directly compounded through hot pressing to manufacture the membrane-coated artificial board, thereby saving the procedures of paper utilization and resin impregnation.
Description
Technical field:
The present invention relates to be a kind of usefulness little/no paper membrane-coated artificial board method that the fibril of receiving strengthens, belong to the technical field that wood-based plate is made.
Background technology:
Membrane-coated artificial board has improved the performance of common wood-based plate, is used widely at aspects such as furniture material, floor, building templates.Along with the demand of market to the environmental type composite constantly increases, natural little/Biodegradable nanometer composite that the fibril of receiving strengthens will occupy an important position, little/humidification of fibril received can improve Compound Material Engineering intensity significantly.In the technical field of wood-based plate, make the method for membrane-coated artificial board and normally use paper at present as carrier, behind the impregnating resin, compound with wood-based plate again.
Summary of the invention:
The present invention proposes a kind of usefulness little/no paper membrane-coated artificial board method that the fibril of receiving strengthens; Its objective is adopt little/receive and be coated in the wood-based plate surface after fibril and the mixed with resin; Again through hot pressing directly with the compound manufacturing membrane-coated artificial board of wood-based plate, thereby the operation of omission paper and impregnating resin
Technical solution of the present invention: a kind of usefulness is little/no paper membrane-coated artificial board method that the fibril of receiving strengthens, it is characterized in that this method comprises following processing step:
One, little/receive the fibril manufacturing, utilize wood pulp to be raw material, through ultrasonic cell disruption instrument; Get power 450～600W; Amplitude 80～100, the broken time is 0.5-1.5 hour, prepare be dispersed in the water little/receive the fibril material; Its concentration percentage by weight is 1.0-1.5%, promptly contain in the water 1.0-1.5% little/receive the fibril material;
Two, little/receive fibril and mixed with resin; Little/fibril the dispersion liquid of receiving is stirred into mixed liquor with water miscible phenolic resins or water miscible melmac, little/weight ratio that the fibril dispersion liquid of receiving mixes with water miscible phenolic resins or water miscible melmac be 1 part of solid little/fibril of receiving adds the phenolic resins or the water miscible melmac of 30～80 parts of solid, water solubles;
Three, base material is prepared, and wood-based plate (like glued board, fiberboard, particieboard) base material moisture content is adjusted to 8～14%, carries out sanding surface again and handles;
Four, surfaces coated resin, with stir little/receive fibril and resin mixture liquor to be coated in ready artificial board substrate surface, consumption be every square metre of wood-based plate surfaces coated 150～220 grams little/receive fibril and resin mixture liquor;
Five, ageing, with surfaces coated little excessively/receive wood-based plate ageing 2-6 hour of fibril and resin mixture liquor, make its surface moisture volatilization part;
Six, hot pressing overlay film, with the surfaces coated after the ageing little excessively/wood-based plate of fibril and resin mixture liquor received sends into hot press hot pressing, 130～180 ℃ of hot pressing temperatures, hot pressing time 1～6 minute;
Seven, post-processed, the membrane-coated artificial board after the hot pressing need nature cooling 1～2 hour, stack then 2～3 days, make its internal stress release, balancing water content.
Advantage of the present invention: adopt little/receive after fibril and mixed with resin be coated in the wood-based plate surface, through hot pressing directly with the compound manufacturing membrane-coated artificial board of wood-based plate, thereby the operation of omission paper and impregnating resin.
