Abstract
The present invention disclose sa production method of new type composite plate material. Said method includes the following steps: firstly, placing two wood-plastic plates on two wide surfaces of die cavity respectively, placing said material on every side surface of four side surfaces of each of two wood-plastic plates, forming a die cavity between said side materials and two wood-plastic plates, heating die to about 80 deg.C, injecting a certain quantity of polyurethane foaming material into the die cavity to implement automatic foaming process, controlling curing time for 20 min., taking out formed plate material. Said invention is simple in production process, and its cost is low.
Description
Technical field
The invention provides a kind of production method of sheet material, particularly this method is a kind of production method of NEW TYPE OF COMPOSITE sheet material.
Background technology
The production method that has a variety of sheet materials in the market, but the sheet material of producing is semi-finished product, need reprocessing just can become finished product, like this, the sheet material that prior art is produced all needs to cut sapwood, product has been caused very big waste, and more the resource to China has caused waste, and sheet material needs complicated processing just can be shaped to relief pattern.
The production method of known composite board is generally following steps: sheet material is inserted in the trigger squeeze, and smear colloid at the mating surface of sheet material, make it bonding, be pressed then, take out sheet material, size is cut sapwood and is handled according to the rules, according to product needed sheet material is processed again, makes door with pattern or wall dividing plate and so on.
Said method has increased the investment of equipment, troublesome poeration, and material loss is big.
In addition, the product that this method is produced in conjunction with insecure, deforms for a long time easily, so can the method that directly process the molded composite board material become the common target of industry understanding.
Summary of the invention
In above-mentioned background of invention, in order to meet the requirement on the industry, a purpose of the present invention is to be to seek a kind of method in the hope of directly producing the sheet forming that need not reprocess, door and wall dividing plate etc. with relief pattern, and long service life, indeformable, intensity is high, thermal insulation and the good method of soundproof effect.
In order to realize purpose of the present invention, this method may further comprise the steps:
1, two blocks of wood is moulded two platyopias that plate places mould cavity respectively;
2, on two wood are moulded four limit faces of plate sapwood is set, this sapwood and two wood are moulded and are formed a die cavity between the plate;
3, the mould temperature is heated to about 80 ℃-100 ℃ of normal temperature;
4, quantitative polyurethane foam material is injected foaming voluntarily in the die cavity;
5, slaking, the curing time was controlled within 15-20 minute;
6, take out sheet forming.
It is that processing wastes such as timber, bamboo wood are ground to powdery through certain processing and high molecular polymer blend process extruder gained that this wood is moulded plate.
This mould can directly be the door shape of relief pattern.
Side at mould is provided with injection port, and is provided with air vent around this mould.This sapwood is provided with and the corresponding filling mouth of mold injects mouth.
This polyurethane injects die cavity by bottler placer.
In this method, polyurethane foam material utilizes plug to clog injection port after injecting.
It is softening and compound with polyurethane material that this method utilizes heat that polyurethane produces in foaming process and pressure to make wood mould plate, need not use the viscose glue based article, prevented the sheet material that viscose glue is produced, use through long-time, viscose glue lost efficacy, and sheet material comes off, for the consumer brings unnecessary trouble.
The present invention compared with prior art has following characteristics:
1, production technology is simple, process equipment that need not be too much, small investment instant effect;
2, die cavity injects polyurethane, and is simple to operate, exempt to clean, do not produce waste material, and the operator grasps easily;
3, produce flexibly, can design any mould, be fit to large-scale production;
4, material fluidity is good, and slaking is fast, has improved operating efficiency, and is responsive to process conditions such as mould temperature, material, exhaust situations.
Description of drawings
Fig. 1 is a method process chart of the present invention;
Fig. 2 is the schematic appearance of the product that the present invention produced.
The specific embodiment
As Fig. 1, shown in Figure 2, process chart for this method, selecting for use wood to mould plate is panel, it is timber that this wood is moulded plate, processing waste straws such as bamboo wood etc. are ground to powdery and handle through certain, with the high molecular polymer blend, make through extruder, at first, two blocks of wood are moulded plate 1 (800mm*3mm*2000mm) places two platyopias of mold cavity as panel respectively, four limits of moulding plate at wood are provided with sapwood, and this sapwood is a flitch 2, make wood mould plate 1 and form a cavity with flitch 2, the side of mould is provided with the polyurethane foam material inlet, and is provided with gas vent on four limits.At this moment, polyurethane foam material is packed in the bottler placer, wait for perfusion, the mould temperature is modulated to 80 ℃, at this moment, by bottler placer polyurethane foam material is injected wood and mould in the cavity that plate 1 and flitch 2 constituted, when the polyurethane material of perfusion reaches a certain amount of, stop perfusion, and clog inlet by plug, then polyurethane material is carried out slaking, will be controlled at the curing time about 20 minutes, can take out sheet forming.
Figure 2 shows that the schematic appearance of the product that invention is produced.It is softening and compound with polyurethane material that this method utilizes heat that polyurethane produces in foaming process and pressure to make wood mould plate 1, need not use the viscose glue based article, prevented the sheet material that viscose glue is produced, use through long-time, viscose glue lost efficacy, and sheet material comes off, for the consumer brings unnecessary trouble.
In addition, this mould still can directly be made for the door shape with relief pattern, so just can make wood mould plate and soften in the polyurethane foam process, and directly form pattern, does not need to reprocess and is directly formed to door.
This production method can make the mode of production of door rise to mechanical mass production by in the past single-piece production, has improved production efficiency greatly, has reduced cost.By the conversion of mold cavity, can one time straight forming go out to have the door of various relief patterns.
This method has not only been saved a large amount of timber for country, and also the comprehensive utilization for timber and processing waste, straw etc. provides an outlet, and its economic benefit and social benefit are real inestimable.
Apparently, according to the description among the top embodiment, the present invention has many corrections and difference.Above-mentioned is preferred embodiment of the present invention only, is not in order to limit claim of the present invention; All other do not break away from following equivalence of not having of this novel spirit that discloses and changes or modify, all should be included in above-mentioned apply for a patent model solid in.
