Abstract
The present invention relates to a manufacturing method of bamboo veneer boards, which has the following technologies: the slitting of strips, processing, gum dipping, drying, hot pressing and solidification. The bamboo veneer boards manufactured by the present invention have the advantages of high strength, favorable temperature adaptability, shock resistance, abrasion resistance, corrosion prevention, no insect damage, etc. The bamboo veneer boards can be widely applied to industries, such as construction, furniture, physical training, traffic, etc., for replacing wood boards.
Description
The present invention relates to a kind of manufacture method of bamboo offset plate.
Timber is the important and in short supply goods and materials of China's construction, and bamboo only needed for 4～6 years from sending out bamboo shoot to becoming a useful person, and timber then needs decades, and wood substituted by bamboo has become the problem of state key research.Existing bamboo offset plate preparation method generally adopts bamboo weaving gummed, the bamboo wood lamination, and the bamboo wood gummed waits several, and basic technology is thin bamboo strips used for weaving to be woven a mat or the bamboo chip gluing is bonded." furniture " 1988,4P5～7 disclose a kind of furniture with bamboo offset plate preparation method, and it is dry that its technological process comprises that thin bamboo strips used for weaving dissects the back, gluing, display, adorn the technology of mould, hot pressing, curing.The bamboo offset plate that this technology is made is a multi-layer sheet, and complex process not only requires for how much sternly to bamboo chip, and institute's product hole piece is obvious, and the easy layering of chance impact is arranged, and intensity is not high, defective such as easily splits, and can not satisfy high-intensity needs (as making the bogie base plate).
The purpose of this invention is to provide a kind of intensity height, adaptability new bamboo glue good, no level amasss into the preparation method of plate.
Bamboo glue of the present invention amasss into plate preparation technology: cut open thin bamboo strip processing → impregnation → oven dry → dress mould, hot pressing, curing.Soon bamboo cuts open to slight and is processed into the certain thickness sheet of slighing, and thin bamboo strip is placed on impregnation in the viscose glue for preparing, the thin bamboo strip oven dry behind the impregnation, and the glue thin bamboo strip dress mould after the oven dry is put press hot pressing into, solidifies to be product.
The bamboo offset plate of the present invention preparation has good, shock-resistant, wear-resistant, corrosion-resistant, the advantage such as do not damage by worms of intensity height, adaptability, and industry, instead of wood plate use can be widely used in building, physical culture, traffic, open a mine etc.As make automobile, train base plate, ore deposit bamboo anchor and draw weld pad plate, blue ball-collecting rack plate, building template etc.
Below in conjunction with embodiment, preparation method of the present invention is described in detail:
Embodiment:
Be used for the preparation that the bamboo glue of carriage bottom plate amasss into plate:
With the bamboo more than 4 years, be processed into thick 0.8～1.2 millimeter, wide 0.8～2 centimetre thin bamboo strip, the sun shines to moisture content 10～15%, impregnation employing solids content is 25～45% the synthetic viscose glue (phenolic resins) of phenol formaldehyde (PF) liquid caustic soda, by glue and thin bamboo strip weight ratio is 1: 5～6 impregnations that feed intake, thin bamboo strip behind the impregnation dried by the fire 3～5 hours, to moisture content≤12% under 30～45 ℃ of temperature, then with the glue thin bamboo strip of drying, according to the quality index requirement, quantitatively there is not level ground dress mould row plate, entrance pressure machine hot-press solidifying, hot pressing temperature is 110～160 ℃, and pressure is 20～60kg/cm
2, through 1.5～2 hours curing, the bamboo glue that promptly becomes a kind of truck carriage bottom plate amassed into plate.Under the situation that the bamboo offset plate need dock, its technology is: with bamboo offset plate docking site mortise, and the gluing of mortise position, the hot pressing of entrance pressure machine is 45～60 minutes then, and temperature is controlled between 110～160 ℃, and pressure is 20～60kg/cm
2Adopt the bamboo offset plate quality index of above technology preparation as follows:
MOR 〉=1100kg/cm
2
Compression strength 〉=600kg/cm
2
Shock strength 〉=100kg/cm
2
Anti-environment intensity :-50～50 ℃
Outward appearance: be the purple light slide plate
The invention is not restricted to the foregoing description, can require preparation to be applicable to that the bamboo glue of various uses amasss into plate according to difference.
Claims (3)
1, a kind of bamboo glue amasss into the manufacture method of plate, comprise that bamboo dissects into dry after thin bamboo strip, drying, the gluing, dress mould, hot pressing, curing process, it is characterized in that: described thin bamboo strip thickness is 0.8～1.2 millimeter, width is 0.8～2 centimetre, dry moisture content is 10～15%, and described photoresist coating process is that impregnation, viscose glue employing solids content are 25～45% phenolic resins; The impregnation ratio: the weight ratio of viscose glue and thin bamboo strip is 1: 5～6; Drying process makes moisture content≤12% for oven dry, bake out temperature are 30～45 ℃ after the described gluing, and described heat pressing process condition is 110～160 ℃ of temperature, pressure 20～60kg/cm
2, the time is 1.5～2 hours, described dress mould is not for having the glue thin bamboo strip of drying behind a certain amount of impregnation level ground dress mould.
2, manufacture method according to claim 1 is characterized in that be 1.5～2 hours described hardening time.
3, manufacture method according to claim 1 is characterized in that bamboo offset plate butt joint technology is: docking site mortise, gluing, hot-press solidifying then.
