Abstract
The invention discloses a rare-earth modification heavy bamboo board. The rare-earth modification heavy bamboo board comprises, by weight, 100 parts to 120 parts of dry bamboo filament sheets, 400 parts to 450 parts of oil-tea-fruit-shell liquidation resin adhesive (the solid content ranges from 20% to 22%), 0.4 part to 0.5 part of penetrant, 5 parts to 6 parts of trifluoroethyl acrylate, 5 parts to 6 parts of nano-polytetrafluoroethylene, 6 parts to 7 parts of dodecafluoroheptyl methacrylate, 0.4 part to 0.5 part of dicumyl peroxide, 2 parts to 3 parts of ammonium molybdate, 1 part to 1.5 parts of boric acid, 1 part to 1.5 parts of amino resin, 5 parts to 7 parts of phenolic resin, 0.4 part to 0.5 part of nanometer yttrium oxide and 0.4 part to 0.5 part of nanometer lanthanum oxide. According to the rare-earth modification heavy bamboo board, glue liquor is modified through the trifluoroethyl acrylate, the nano-polytetrafluoroethylene and the dodecafluoroheptyl methacrylate, and the water resistance, the oil resistance, the corrosion resistance and the antifouling performance of the heavy bamboo board can be improved; and due to the ammonium molybdate, the boric acid, the phenolic resin, the nanometer yttrium oxide and the nanometer lanthanum oxide, the surface performance of bamboo filaments is improved, glue liquor permeation is promoted, and therefore the bonding firmness, the rigidity and the bending strength of the board are improved.
Description
Technical field
The present invention relates to and heavy bambooly make field, particularly relate to a kind of rare earth modified heavy bamboo board and preparation method thereof.
Background technology
Bamboo is as the second largest forest reserves of China, and because it has the characteristics such as breeding power of regeneration is strong, growth cycle is short, material is excellent, it is industrial and commercial value is day by day remarkable.Bamboo wood, by mechanical-physical processing, chemical process, produces various bamboo product, wood substituted by bamboo, reduces wood consumption, effectively can alleviate the contradiction between timber supply and demand.
Heavy bamboo board splits thin bamboo strip wire drawing by bamboo wood, discongests, then through charing antisepsis process, compressing through high pressure.The sheet material of preparation has the performances such as high strength, high density, uvioresistant, water-fast mildew-resistant, environmental protection, and is widely used in all kinds outdoor materials such as outdoor flooring, high-grade furniture decoration panel, building structure beam column material, building construction sheet material, outdoor garden goods, boat deck, freezer plate and container bottom board.There is thickness swelling rate problem bigger than normal in current heavy bamboo board, and oil resistivity, wearability, crack resistence, soil resistance, antibiotic property, anti-discoloration, intensity are good not enough, and weight is large, needs improvement.
Summary of the invention
The object of the present invention is to provide a kind of rare earth modified heavy bamboo board and preparation method thereof, this heavy bamboo board glue quick permeation, adhesive fastness be high, hardness and bending strength high.
Technical scheme of the present invention is as follows:
A kind of rare earth modified heavy bamboo board, is characterized in that being made up of the raw material of following weight portion: dry bamboo sheet 100-120, oil-tea camellia husks liquefied resin adhesive (solids content is 20-22%) 400-450, bleeding agent 0.4-0.5, acrylic acid trifluoro ethyl ester 5-6, nanometer polytetrafluoroethylcomposite 5-6, dodecafluoroheptyl methacrylate 6-7, dicumyl peroxide 0.4-0.5, ammonium molybdate 2-3, boric acid 1-1.5, amino resins 1-1.5, phenolic resins 5-7, nano yttrium oxide 0.4-0.5, nano lanthanum oxide 0.4-0.5.
Described rare earth modified heavy bamboo board, is characterized in that:
(1) dry bamboo sheet is carried out boiling and carbonization, then carry out drying to moisture content be 6-9%;
(2) by oil-tea camellia husks liquefied resin adhesive (solids content is 20-22%), the mixing of nanometer polytetrafluoroethylcomposite, acrylic acid trifluoro ethyl ester, dodecafluoroheptyl methacrylate, ammonium molybdate, boric acid, phenolic resins, nano yttrium oxide, nano lanthanum oxide, be heated to 60-70 DEG C, add dicumyl peroxide again, stirring reaction 30-40 minute, add other residual components again, mix, obtain glue;
(3) bamboo sheet that (1) step obtains is put into glue dipping 10-12 minute, then ultrasonic process 1-2 minute, drench dry unnecessary glue, shone by the sun or drying room oven dry, until thin bamboo strips used for weaving moisture content is down to 13-18%, then through the cold moudling → solidification → demoulding → tack → one-tenth sheet material, to obtain final product.
Beneficial effect of the present invention
The present invention uses acrylic acid trifluoro ethyl ester, nanometer polytetrafluoroethylcomposite, dodecafluoroheptyl methacrylate, carries out modification to glue, can improve resistance to water, oil resistivity, wearability, the soil resistance of heavy bamboo board, reduces board dimension distortion; By using ammonium molybdate, boric acid, phenolic resins, nano yttrium oxide, nano lanthanum oxide, improving the surface property of bamboo silk, promoting glue infiltration, thus the adhesive fastness of raising sheet material, hardness and bending strength.
