For solving the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of particleboard with zero-formaldehyde emission, is made by thermoplastic powder and two kinds of compositions of chips, and using thermoplastic powder as adhesive, melts, glues together chips.
Further, described thermoplastic powder is low density polyethylene (LDPE) powder or low density polypropylene powder or high-density polyethylene powder or high density poly propylene powder.
A manufacture method for particleboard with zero-formaldehyde emission, includes following steps:
A. thermoplastic powder and chips are fully uniformly mixed, thermoplastic powder is attached to around the surface of chips;
B. the chips that is attached with thermoplastic powder is mated formation on metallic plate;
C. will pave chips and send into hot press together with metallic plate and carry out hot pressing, thermoplastic powder is melted completely;
D. the chips after hot pressing being sent into cold press fast together with metallic plate colds pressing, under condition of high voltage, carry out cooling, make the thermoplastic powder that melted under high pressure progressively cooling and combine closely with chips, form and there is good bonding strength and not containing the particieboard section bar of formaldehyde;
E. particieboard section bar is sheared successively, sanding, make particieboard finished product.
Further, the hot pressing temperature of described " send into hot press together with metallic plate and carry out hot pressing paving chips " is 140 DEG C～220 DEG C, and hot pressing pressure is 15 KG/cm
2～20 KG/cm
2.
Further, described thermoplastic powder is low density polyethylene (LDPE) powder or low density polypropylene powder, and by paving chips, to send into together with metallic plate the hot pressing temperature that hot press carries out hot pressing be 150 DEG C～160 DEG C.
Further, described thermoplastic powder is high-density polyethylene powder or high density poly propylene powder, and by paving chips, to send into together with metallic plate the hot pressing temperature that hot press carries out hot pressing be 190 DEG C～200 DEG C.
Further, the pressure of colding pressing of described " chips after hot pressing is sent into cold press fast together with metallic plate colds pressing " is 20 KG/cm
2～30 KG/cm
2.
Further, the fineness of described thermoplastic powder is more than 100 orders.
Further, " thermoplastic powder and chips are fully uniformly mixed " before, first chips is dried to processing.
Further, described metallic plate is aluminium sheet or steel plate.
The invention has the beneficial effects as follows:
The present invention passes through technique scheme, can produce zero formaldehyde, bonding strength is high, water resistance is good, the high-quality particieboard of asepsis environment-protecting, and production process can not produce the toxic gases such as a large amount of formaldehyde yet, both ensured direct labor's personal safety, also can not cause the pollution of surrounding enviroment, be conducive to penetration and promotion.
Brief description of the drawings
Fig. 1 is the schematic flow sheet of the manufacture method embodiment of a kind of particleboard with zero-formaldehyde emission of the present invention;
Fig. 2 is the schematic diagram of in the manufacture method embodiment of a kind of particleboard with zero-formaldehyde emission of the present invention, the chips that is attached with thermoplastic powder being mated formation on metallic plate.
Detailed description of the invention
In order to make object of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
As shown in figs. 1 and 2,
A kind of particleboard with zero-formaldehyde emission described in the embodiment of the present invention is made by thermoplastic powder and two kinds of compositions of chips, and using thermoplastic powder as adhesive, melts, glues together chips.The manufacture method of this particleboard with zero-formaldehyde emission, specifically can include following steps:
Steps A 1. is fully uniformly mixed thermoplastic powder 1 and chips 2, and thermoplastic powder 1 is attached to around the surface of chips 2;
Steps A 2. mats formation at metallic plate 3(the chips 2 that is attached with thermoplastic powder 1 as aluminium sheet or steel plate) upper, as Fig. 2;
Steps A 3. will pave chips 2 and send into hot press together with metallic plate 3 and carry out hot pressing, and hot pressing temperature is 140 DEG C～220 DEG C, and hot pressing pressure is 15 KG/cm
2～20 KG/cm
2, thermoplastic powder 1 is melted completely;
Steps A 4. is sent into fast cold press by the chips after hot pressing 2 together with metallic plate 3 and is colded pressing, and carries out cooling (being cooled to below 80 DEG C) under condition of high voltage, and the pressure of colding pressing is 20 KG/cm
