Abstract
A method of making fiber moulded product using medium density fibreboard as base material, that is, using medium density fibreboard as base material which is treated by special activating agent, softening agent and softening penetrant, then put in special mould and hot pressed, hot press temperature is 120-190 deg.C pressure is 10-60 Kg/sq.cm, hot press time is 3-6 min.. Said method can produce high density fibreboard moulded product with convex and concave texture or conrex and concave pattern, which can be used as door sheet, decorative plate and others.
Description
A kind of with the method for medium density fibre board (MDF) as base material manufacturing fibre mould pressing product, relate to and utilize existing medium density fibre board (MDF) as base material, carry out the wood-based plate secondary operations process of deep processing, belong to the technical field of wood-based plate secondary operations.
The manufacturing of fibre mould pressing product is a known technology, United States Patent (USP) 4198460 and 4622190 has been introduced the once molding formed technology of once molding formed and a kind of wet method of a kind of dry method respectively, these two kinds of technologies all are to be raw material with the string, form slab through dry method or wet method, it is once molding formed to put into mould then.This pressing has good moulding, the clear wash rice of surface grain, and the intensity height is a kind of fiber with excellent pressing; But production line will be from the string preparation, and whole production line is actual to be exactly a medium density fibre board (MDF) factory, invests huge.Chinese patent 93109707.X has invented a kind of wet processing first step of utilizing and has produced the wet-process fiber board base material, and second step was put into specific mould with the wet-process fiber board base material again, and secondary hot pressing is produced the method for fiber moulded door skin and other fibre mould pressing product.Wet method secondary mould pressing technology, need the special special-purpose base material of making, can not directly utilize the product of wet-process fiber board factory as base material, wet method secondary mould pressing technology is complicated, clamp time is also long partially, particularly the clear wash rice degree of the surface grain of product is also not satisfactory, and product quality still can't be compared with the one-step mould goods with qualification rate.Germany is than the Bison method of loose company invention, and promptly dry method secondary mould pressing method can directly utilize 5mm thick, and density is 0.65～0.68kg/cm
3Medium density fibre board (MDF) as base material, with the one side of backing material plate through spray steam handle after, being pressed into thickness under 180 ℃, 8Mpa hot pressing condition is 3mm, density is 1.13g/cm
3The fiber molded door skin, the advantage of this method is to utilize common 5mm medium density fibre board (MDF) as base material, secondary hot pressing becomes fiber moulded door skin goods, molding apparatus is simple than one-step mould, but the still clear inadequately wash rice of product surface wood grain, because be that thermoplastic is steamed in the single face spray, effect is unsatisfactory, back side protuberance is prone to crackle.
The object of the invention is to solve the problems referred to above of prior art, thereby proposes a kind of secondary mould pressing technology of making fibre mould pressing product with medium density fibre board (MDF) as base material.
Method of the present invention is to utilize the hot pressing in specific mould after specific activator and softening agent activate, soften of existing medium density fibre board (MDF), can make fiber moulded door skin, decorative panel and the automotive upholstery that there be Z-Correct bump mapping Z-correct and convex-concave pattern in the surface.
According to the used medium density fibre board (MDF) of method of the present invention can be wooden or non-wooden material makes, and comprises softwood, broadleaf, bamboo wood, bagasse, reed, waste of flax, straw etc.
According to method of the present invention, to activate fully before the used medium density fibre board (MDF) mold pressing, soften, adopt specific activator, softening agent and softening bleeding agent, fully sprinkling is softened or is soaked softening, the softening time, softening back medium density fibre board (MDF) moisture content was 15～40% by the thickness decision of material and backing material plate.Used activation softening agent has polyacrylamide solution, poly-vinyl alcohol solution and polyglycol solution and their mixture etc., and bleeding agent has ethanolic solution etc.Medium density fiber plate substrate after softening should mold pressing in reasonable time.Mold surface temperature should be 120～190 ℃, molding pressure 10～60kg/cm
2, time 3～6min.
According to method of the present invention, the density of medium density fiber plate substrate can be at 550kg/m
3～1000kg/m
3In the scope, the fiber moulded door skin density increase by 3～30% through compression molding reaches 900kg/m
3More than, become the high-density fiber pressing.
According to method of the present invention, the high-density fiber pressing surface after mold pressing can overlay melamine impregnated paper, impregnated cloth or veneer, also can directly spray solid-shade paint or make to show line paint.
According to method of the present invention, the high-density fiber pressing that medium density fiber plate substrate secondary mould pressing goes out, the clear wash rice of wood grain, it is dark to reach 0.18mm, and the relief pattern profile is clear, and flawless is basic identical with the quality of item of dry method one-step mould after painting.
According to method of the present invention, the adhesive that uses in the medium density fibre board (MDF) can be amino resins, phenolic resins, isocyanates, the spontaneous gum resin of lignin.
Example 1: with the poplar medium density fiber plate thickness 4mm that continuous rolling process is produced, breadth 800 * 2100, IB=0.5, MOR=25kg/cm
2, softening with the activation softening agent of 10% concentration, softening back moisture content 30% is put into the special door skin mould that relief pattern and wood grain are arranged, and 160 ℃ of mold surface temperatures are forced into 45kg/cm
2, press time 4min.Suppress to such an extent that be of a size of the high-density fiber moulded door skin of 3.2 * 800 * 2100mm, its relief pattern back flawless, the clear wash rice of surface spray white paint back wood grain records its IB=0.55MPa, and MOR=31MPa all increases than base material.
Example 2: with the pine medium density fibre board (MDF) that the continuous flat method is produced, thickness 3mm, breadth 800 * 2100, IB=0.6MPa, MOR=36MPa after example 1 the same manner mold pressing, is of a size of 2.6 * 800 * 2100mm, IB=0.66Mpa, MOR=39Mpa.
