Summary of the invention
In order to overcome shortcoming and deficiency existing in the prior art, it is multiple that the purpose of the present invention is to provide a kind of light fibres Plywood material, the present invention be easy to get extensively, cheap agriculture waste fibres or waste textile fiber produced it is high-strength The light fibre plate of degree, producing adhesive used in plate is organosilicon-modified polyvinyl adhesive, has both remained poly- second Enol adhesive safety and environmental protection, formaldehydeless, high bond strength, low cost advantage, while overcoming Water-Resistance of PVA not The defect of foot, and joined enhancement layer in plate, timber intensity, hardness and water resistance can be effectively improved.
Another object of the present invention is to provide a kind of production methods of light fibre composite board.
The technical solution adopted by the present invention to solve the technical problems is:
A kind of light fibre composite board, the plate include the finish coat, enhancement layer and core set gradually from outside to inside Material forms interlayer structure；The core material is organosilicon-modified polyvinyl adhesive bond agriculture waste fibres or waste and old spinning Fabric fiber is pressed and molded and obtains, and organosilicon-modified polyvinyl adhesive weight is the agriculture waste fibres or waste and old spinning 0.1-15 times of fabric fibre weight；The organosilicon-modified polyvinyl adhesive is organosilicon modifier and polyvinyl alcohol water Solution is compounded and is obtained, and the weight percent of polyvinyl alcohol is 0.1-15%, the weight percent of organosilicon modifier in adhesive For 0.1-25%, remaining is water polishing to 100%.
Further, the organosilicon-modified polyvinyl adhesive weight is the agriculture waste fibres or waste and old spinning 1-10 times of fabric fibre weight.
Further, the weight percent of polyvinyl alcohol is 1-15%, the weight of organosilicon modifier in the adhesive Percentage is 1-15%, remaining is water polishing to 100%.
Further, the organosilicon modifier is 3- aminopropyl triethoxysilane, 3- (2,3- epoxypropoxy) Trimethoxy silane, 3- methacryloxypropyl trimethoxy silane, N- (2- aminoethyl) -3- aminopropyl trimethoxy silicon One of alkane, vinyltrimethoxysilane, vinyltriethoxysilane, methoxyl group silicone oil or silicone acrylic emulsion are a variety of.
Further, the agriculture waste fibres be corn stalk fiber, rice straw fiber, wheat straw fiber or One of sugarcane fibre is a variety of.
Further, the enhancement layer to be epoxyn by gauze or non-woven fabrics be bonded to the core surfaces and At.
Further, the finish coat is melamine impregnated paper, Recombinant Wood, aluminium foil, hot rolling cloth or eedle-punched non-wovens.
A kind of production method of light fibre composite board, the method are as follows:
(1) the organosilicon-modified polyvinyl adhesive is prepared first, then by agriculture waste fibres or waste and old weaving Product fiber and the organosilicon-modified polyvinyl adhesive are uniformly mixed, and then carry out predrying, remove most of moisture content；
(2) then by the fiber that step (1) prepares be put into it is hot-forming in mold obtain the core material, hot pressing temperature is 120 DEG C~240 DEG C；
(3) the core surfaces epoxyn bonding gauze or non-woven fabrics obtained in step (2), is made institute State enhancement layer；
(4) finish coat is bonded in the plate surface that step (3) obtains
The present invention has the advantage that
(1) fiber used in light fibre composite board of the present invention is agriculture waste fibres (such as corn stalk fiber, rice Stalk fibre, wheat straw fiber, sugarcane fibre etc.) or waste textile fiber, fibrous raw material is from a wealth of sources to be easy to get, and price is low The big use of small material, waste benefit honest and clean, and ecological resources will not be damaged, and realize agricultural wastes and waste textile With having achieved the effect that ecological, environmental protective, economized on resources；
(2) producing adhesive used in plate is organosilicon-modified polyvinyl adhesive, both remains polyvinyl alcohol glue Stick safety and environmental protection, formaldehydeless, high bond strength, low cost advantage, while overcome Water-Resistance of PVA it is insufficient lack It falls into.
(3) core material in plate of the present invention uses hot press forming technology, package enhancement layer and finish coat outside core material, preparation Obtained plate has high-intensitive, high rigidity and water resistance, and service life extends.
(4) preparation cost of plate of the present invention is low, simple process, before practical value with higher and good market Scape.
