Abstract
The present invention relates to a composite board which is formed in a mode that 30 to 70% of waste and old plastic, 30 to 70% of fibred material, at most 15% of reinforcing material, at most 5% of antistatic agent, at most 5% of reinforcing agent and at most 30% of anti-smoke flame retardant are sorted, crushed, washed, dried, formulated, mixed, manually moulded, pressed in a heat mode, etc. The composite board has the advantages of high strength, good moisture-proof performance, good flame retardant, good wear resistance, good impact resistance, easy processing performance and utilization of waste materials, etc., is favorable for environmental protection, can be used for decoration, furniture manufacture, packing, transportation, etc., and has wide purposes.
Description
The present invention relates to the composite sheet and the technology thereof of a kind of composite sheet, particularly fibrous material and plastics.
In the past, glued board, shaving board, medium-density plate etc. all used timber and resene tackiness agent in a large number, not only consume a large amount of timber, and the cost of product were also high, and produced a large amount of obnoxious flavoures that human body had the intense stimulus effect in process of production.At present, the production of domestic non-returnable container material and application development are very fast, a large amount of soft packagings, plastic waste bag, plastic sheeting for farm use are used the back environment are caused very big pollution, how fully to effectively utilize these wastes and are people and making great efforts the important topic studying, develop.
The objective of the invention is to invent a kind of composite fibre-plastics board material and production technique thereof, so that utilize the sheet material of fibrous material and waste or used plastics production performance excellence.
The present invention utilizes the mixture of plastic waste, fibrous material or plastics and fibrous material, adds certain auxiliary agent, is processed into sheet material by hot-pressing processing, and the prescription of sheet material of the present invention is (weight ratio):
Plastics _ _ _ _ 30～70%
Fibrous material _ 30～70%
Strengthen material _ _ _≤15%
Static inhibitor _ _ 0～5%
Toughener _ _ _ 0～5%
Smoke suppressor is fire-retardant _ and 0～30%
Wherein said plastics are soft waste or used plastics, as plastics bag or film, woven bag etc., fibrous material can be waste paper, straw, wood fragments bits or glass etc., the enhancing material is a strips of sheet metal, as aluminum foil strip etc., wherein static inhibitor can be carbon powder, and toughener is polyacrylic ester (ACE or PAE), and the smoke resistance flame resistance agent can be following one of several: polymolecularity hibbsite, red phosphorus, ammonium polyphosphate.The too much adding (surpassing 10%) of smoke resistance flame resistance agent can make the strength degradation of plate.The adding of toughener can make the shock resistance of plate improve 3～5%.Described static inhibitor, whether the adding of fire retardant and toughener is decided according to the requirements such as static resistance, flame retardant resistance and intensity of plate.
Accompanying drawing is the schematic flow sheet of production technique of the present invention.
As shown in drawings, industrial offal, production waste plastics and the fibrous material etc. retrieved are carried out sorting, select and meet the present invention's needed material of filling a prescription, be crushed to length＜70mm, the strip fragment of wide＜20mm, clean then, clean rate will reach more than 90%, the material of cleaning is sent into the drying plant drying of built-in magnet and vibratory screening apparatus and is removed iron plate or iron filings and sandy soil, to clean, dried plastics, fibrous material and strengthen material etc. with auxiliary agent by recipe ratio batching mixing, wherein plastics distribute in mixed material and want even.The material of mixing is packed in the mould through hot-forming, surface decoration material hot repressing moulding such as covering wooden single-skin drum also can be spread in hot-forming preceding material surface after raw material was gone into mould, produce the sheet material of good decorating effect, thereby reduce the technology of used usually second glue spreading compound surface finishing material.Heating temperature wherein is 130 ℃-180 ℃, and pressure is 1MPa～2.5MPa, and the product that is pressed into is processed into finished product through cutting, deburring etc.Can add the sheet material that material modified production has property when going into mould, change different moulds and can be pressed into difform product, maximum can be made into the plate that specification is 2.44 * 1.22m when producing sheet material, thickness can≤20mm.
Utilize paper, mould, aluminum foil composite---when sheet material of the present invention is produced in soft packaging, plastics are polyethylene, consumption is 35%, fibrous material is a cardboard, consumption is 55%, and the enhancing material is an aluminium foil, and consumption is 10%, because of client's no requirement (NR), so static inhibitor, smoke resistance flame resistance and toughener do not add.By described production technique production, wherein Heating temperature is 150 ℃ with raw materials used, pressurization 1.2MPa, and the plate property of making is:
Folding strength _ _ 〉=25MPa
Bonding strength _ _ 〉=1.0MPa
Hold screw power _ _ 〉=1000N
Density _ _ _ _ about 900kg/m
3
Water-intake rate _ _ _ immersed in the water 2 hours, be not more than 5%
Shock resistance _ _ the 0.3kg copper ball is from the 1.2m free-falling, do not destroy after the impact
Composite plate of the present invention have intensity height, protection against the tide, fire-retardant, wear-resisting, shock resistance, good insulation preformance, Workability is good, utilizes the advantages such as waste material environmentally safe, in building, vehicle and the decoration of ships, furniture system The aspects such as work, packed and transported have extensive use.
Claims (3)
1. fiber-composite panel of plastic material, it is characterized in that: with cardboard, plastics, aluminum foil composite-soft packaging is that raw material is made through hot pressing, wherein said plastics are polyethylene, consumption is 35% weight, the consumption of fibrous material cardboard is 55% weight, aluminium foil is for strengthening material, and consumption is 10% weight.
2. the production technique of the described fiber-composite panel of plastic material of claim 1, it is characterized in that: described processing step is: be crushed to length＜70mm after the sorting, the strip fragment of wide＜20mm, clean drying, mix again, go into mould, hot pressing forms, and wherein Heating temperature is 130 ℃～180 ℃, is pressurised into 1～2.5MPa.
3. the production technique of fiber-composite panel of plastic material according to claim 2 is characterized in that: before hot-forming, the material surface also can be spread and be covered wooden single-skin drum surface decoration material, and then hot-forming, produces the sheet material of good decorating effect.
