Abstract
The invention relates to a highintensity flakeboard and the producing method of the flakeboard, the material of the flakeboard per stere comprises 740-760 kg wood paring of 1.5-3.0 percent moisture content, 140-145 kg of high strength stickiness adhesive and 6-8 kg of water. The invention has the advantages of reasonable formula and simple producing method, the productions are suitable for being used as clapboards for book cabinets, cupboards, laboratory tables, bar counters and board tables, all of which are capable of bearing large load for a long time.
Description
One, technical field:
The present invention relates to a kind of particieboard and production method thereof, particularly a kind of high-strength shaving board and production method thereof.
Two, background technology:
Present furniture and indoor decoration particieboard mostly are applied to dividing plates such as bookcase, cabinet, experimental bench, bar desk and pallet because load-bearing is big, time length is prone to flexural deformation, do not reach the load-bearing requirement, and this is the deficiency of existing particieboard.
Three, summary of the invention:
The objective of the invention is to invent a kind of high-strength shaving board and production method thereof, this particieboard can not deform under the condition of long-time, big load-bearing, in order to overcome the deficiency of existing particieboard.
Purpose of the present invention can realize by following embodiment: every cubic metre of wood particle 740-760kg, high-strength adhesive 140-145kg, water 6-8kg that includes water content at 1.5-3.0% of the raw material of this high-strength particieboard.
The high-strength adhesive raw material packet of this high-strength shaving board contains (consumption per ton) formaldehyde 700-780kg, urea 450-500kg, melamine 50-200kg, NaOH 15-20kg, hydrochloric acid 5-10kg, generates through addition and polycondensation reaction, and its index is as follows:
A. outward appearance: white or light brown, there is not mechanical impurity;
b.PH≈8.5-10；
C. solids content: 60-70%;
D. viscosity: 250-450mpa.s;
E. free formaldehyde content :≤0.1%;
F. water Combination: 〉=2.5 times;
G. its production method is: formaldehyde, urea, melamine, NaOH, the hydrochloric acid of above-mentioned weight portion are dropped into reactor successively, carry out addition reaction, go out finished product glue.
The production method of this high-strength particieboard be with the wood particle drying of above-mentioned consumption after the 1.5-3.0% water content by its geometry, with thickness 1.4mm is that boundary is through the mechanical oscillation sorting, initial gross separation goes out two kinds of the dried wood shavings of dried wood shavings of thick sandwich layer and thin top layer, then with high-strength adhesive, water all becomes two parts after fully being mixed into epoxy glue, add in two kinds of wood shavings with the part by weight of 11-13% and 17-20% respectively, through mechanical agitation, the dried wood shavings of dried wood shavings of thick sandwich layer and thin top layer that will contain the epoxy glue of high-strength adhesive are mated formation in 6.5: 3.5 ratio, use unit are under the situation of 30kg/cm2 the slab that paves at last, carry out concora crush with 170-210 ℃ temperature and become plate.
Advantage of the present invention is: be applicable to that long bookcase, cabinet, experimental bench, bar desk and pallet etc. of big and time of load-bearing use dividing plate, and have better waterproof energy and fire resistance.
Four, description of drawings:
Fig. 1 is technological process of production figure of the present invention
