Description

It is a kind of through plastics spray fusing and the orientation laminated particle-board containing plastic tab

Technical field

The present invention relates to field of compound material, and in particular to a kind of orientation through plastics spray fusing and containing plastic tab is compound Particieboard.

Background technology

Wood plastic composite is one of fastest-rising advanced polymer composites of field of compound material.It squeezes out, injection It is the method for three kinds of main production wood plastic composites with hot pressing, but squeezes out the size that its product is limited with injection, Therefore pressure sintering is to produce the best practice of large format wood plastic composite.Existing wood plastic composite manufacturing requirements wood The size of matter raw material is sufficiently small, and the powdery wood fibre of usually used 40~100 mesh of industry, the milling of raw material not only increases Energy consumption, and be also dust pollution and the source of noise pollution.Using large scale raw material, the prototype structure that can keep raw material is few It is destroyed, so as to be conducive to increase the properties of product, and energy-saving and noise-reducing can be played the role of.The master of wood plastic composite Raw material is wanted to include wood material and plastics, in cost, the price of plastics is higher than the price of wood material, therefore improves in product The content of wood material can reduce the cost of product.However, in existing wood plastic composite wood material mass fraction one As 20% to 50%, when wood material content is higher than 50%, the poor fluidity of wood material and plastic hybrid, with equipment pipe The frictional resistance of wall is larger, the defects of causing product lack of homogeneity and face checking, therefore how to pass through new technique and improve wood The content of wood material becomes the emphasis and hot spot of research in plastic composite materials.

China is large agricultural country, and agricultural crop straw yield is big, distribution is wide, species is more, although stalk is always for a long time Life of farmers and the precious resources of agricultural development, but stalk brings the environmental problems such as air pollution by incorrect utilize.With The progress of technology, becomes a kind of new tool using stalk with stalk manufacture wood-based plate.Stalk surface have waxy substance and Pectin, if being dealt with improperly when manufacturing wood-based plate with stalk will face that internal bond strength is inadequate, comprehensive mechanical property is insufficient Defect；And stalk is herbaceous plant, its growth time limit is short, relatively low compared with content of lignin therein for timber；Stalk board Apparent mass is bad, it is also made to be subject in the application of the furniture manufacturing field, architectural decoration engineering field of high added value Some limitations.The defects of making full use of stalk resource, and overcoming stalk improves internal bond strength, the content of lignin of stalk board, It is current problem to be solved to improve its mechanical property and apparent mass.

During conventional thermocompression method produces wood-plastic composite (WPC), the density of plastic grain is more than the close of wood material Degree, so as to which in mixed process, the big plastics of the density fiber small with density is difficult to be uniformly mixed or even mating formation and hot pressing Cheng Zhong, the big plastic grain of density will be slided to the bottom of slab to be leaked, so as to cause plastic content and density in product thickness direction On be unevenly distributed.Although long size wood material is conducive to increase the performance of final products, on caused by grain plastic It states sliding leakage and unevenly distributed phenomenon becomes apparent from.This just directly results in material and is unevenly distributed, easily on the thickness direction of slab Assemble, so as to which undaform Vertical density gradient can be formed（VDP）, and then influence the mechanical property and apparent mass of material. Plastic powders is made to mat formation as required, and realize the thickness that is homodisperse, controlling plastics pave-load layer after the completion of mating formation of powder particle Degree is the major issue for currently needing to solve.Also lack one kind in the prior art simultaneously and orientation is being prepared based on the plastics mode of dusting During wood-plastic composite particleboard, plastic powders is allow to uniformly disperse simultaneously, avoid plastic powders because of centralized head load or fire The method of the wood plastic composite of the defects of discoloration that flame burns and occurs, denaturation, burning.
