Abstract
The present invention provides an environment-protecting regenerated wood residue density board and its preparation method. It is made up by using (by weight portion) 20-35 portions of main raw material, 5-15 portions of primary density board sand-grinding powder and 3-10 portions of urea-formaldehyde glue through a certain preparation process. The above-mentioned main raw material is the offcut waste material obtained by producing veneer board, including one of sawdust, wood shavings, tree bark and cotton stalk or mixture of more than two kinds of them.
Description
1, technical field
The present invention relates to a kind of technology of preparing of artificial building board, specifically a kind of environmental protection regenerative wood residual density board and preparation method thereof.
2, background technology
In the building board production process of prior art, can produce a large amount of leftover bits after needing to be sawn into the size of regulation behind the pressboard, thereby produce a large amount of industrial refuses environment is caused severe contamination, handle then can produce large quantity of exhaust gas, can pollute air equally if burn.Good solution is not also arranged at present.
3, summary of the invention
The purpose of this invention is to provide a kind of environmental protection regenerative wood residual density board to leftover bits reuse again and preparation method thereof.
The objective of the invention is to realize in the following manner, environmental protection regenerative wood residual density board is to be made by following materials of weight proportions: main material 20-35 part; Primary density board sanding powder 5-15 part; Urine aldehyde glue 3-10 part, wherein main material is the leftover bits of plywood production; Sawdust; Wood shavings; The composition of one or more in bark, the cotton stalk;
Preparation process is as follows:
The first step: pulverize, the bulk material is ground into the 0.5-1mm granularity with the powder machine;
The 3rd step: oven dry, adding dryers such as good material of powder and saw foam are dried, again sanding powder is dried 5-25 minute baking needed time separately;
The 3rd step: glue mixing, in the oven dry material, add urine aldehyde glue, material glue ratio is 25: 4, it is standby to stir, and adds urine aldehyde glue in sanding powder, Ratio of filler bitumen 10: 1, it is standby to stir;
The 4th step: bed board, four ribs are placed on the steel plate, form a groove, the sanding powder of glue mixing is evenly spread one deck on steel plate, evenly spread the wooden slag of one deck glue mixing again, the superiors repave the sanding powder of one deck glue mixing, with dry plate its slight pressing, put steel plate, repeat above method, repave second, the 3rd, the 4th ... the number of shop meets the pressing machine and meets;
The 5th the step: the steel plate of the centre being completed sizing material pushes the pressing machine, controlled pressure 20-40 atmospheric pressure,, temperature is controlled at 90 ℃-110 ℃, suppresses to get final product ejecting plate in 20-4O minute;
The 6th step: saw the limit behind the ejecting plate, burr around half-finished are amputated, make standard-sized semi-finished product with Sawing machine;
The 7th step: sanding, with sander the sanding processing being carried out on half-finished surface is finished product.
