The invention discloses a mildewproof dampproof health-care fiber composite board. The fiber composite board is characterized by being prepared from the following raw materials in parts by weight: 40-60 parts of rice straw, 20-30 parts of camellia oleosa seed cakes, 10-15 parts of a urea-formaldehyde resin adhesive, 2-4 parts of polyvinyl butyral, 5-10 parts of diatomaceous earth, 5-10 parts of talcum powder, 0.3-0.5 part of zinc pyrithione, 2-4 parts of tung oil, 4-8 parts of silicone acrylic emulsion, 4-6 parts of resin emulsion, and 4-8 parts of composite nanoparticle suspension. The fiber composite board disclosed by the invention has good mechanical performance, high weather resistance, good waterproof performance, good dampproof performance, good sterilizing efficacy, good mildew preventing efficacy, and good sanitary performance; besides, the fiber composite board has the health-care efficacies of improving the immunity of human bodies, relieving fatigue and eliminating vivotoxin; the fiber composite board can remove peculiar smell and purify air, so that the fiber composite board is high in practicability.
Description
Technical field
The present invention relates to composite board field, be specifically related to a kind of mildew resistant moistureproof health fiber composite plate and preparation method thereof.
Background technology
Density board also claims fiberboard, is with wood fibre or other plant fiber for raw material, applies the artificial board that Lauxite or other adhesive be suitable for are made, is mainly used in laminated flooring, door-plate, partition wall, furniture etc.Density board smooth surface is smooth, material is fine and closely woven, stable performance, edge are firm, is easy to processing, avoids rotten, the problem such as to damage by worms, and the good decorative property of plate surface.But density board mechanical performance is poor, timber intensity is not high, yielding, and bearing capacity is not strong, and moisture resistivity is poor, meets water and easily expands distortion.
Germanium is a kind of eare scattered metals, has good health-care effect, and it mainly lessens fatigue on the impact of human body, stimulate circulation, gets rid of the aspects such as vivotoxin.In addition, it has good therapeutic action to various diseases, as antitumor, treatment senile dementia, strengthen immunologic function, delay senility, prevention of arterial sclerosis, reduce blood viscosity, resisting rheumatoid disease arthritis, regulate endocrine, analgesic antiphlogistic, hypotensive etc.Germanium under certain condition can anion releasing automatically, reduce the oxygen radical produced from the polluter, nitrogen oxide, cigarette etc. of air, reduce over the harm of many active oxygens to human body, the floating dust in air of neutral zone positive electricity is without sedimentation after electric charge, air is purified, has prevention air conditioner disease, improve PFT, strengthen the effects such as resistance against diseases, improving water flood, fresh air, smoke abatement and dust control.
Summary of the invention
The object of this invention is to provide a kind of mildew resistant moistureproof health fiber composite plate, good mechanical property, durability are high, and have good health-care effect.
The present invention is achieved by the following technical solutions:
A kind of mildew resistant moistureproof health fiber composite plate, it is obtained by the raw material of following weight parts:
Rice straw 40-60, tea seed grouts 20-30, urea-formaldehyde resin adhesive 10-15, polyvinyl butyral resin 2-4, diatomite 5-10, talcum powder 5-10, ZPT 0.3-0.5, tung oil 2-4, Silicone acrylic emulsion 4-8, rosin milk 4-6, composite Nano suspension 4-8;
Wherein composite Nano suspension is made up of the raw material of following weight portion: Ge 1-2, nano titanium oxide 0.5-1, polyethylene glycol 1-2, Tween-80 0.1-0.2, water 10-20; Polyethylene glycol and Tween-80 are first added to the water 600-1000r/min to stir 20-30min by the preparation method of composite Nano suspension, then add Ge and nano titanium oxide and ultrasonic disperse 10-15min, to obtain final product.
A preparation method for mildew resistant moistureproof health fiber composite plate, comprises the following steps:
(1) pulverize through pulverizer after rice straw and tea seed grouts are clean, drying, obtain composite fibre; Again Silicone acrylic emulsion, composite Nano suspension and rosin milk mixed and stirred, being sprayed in described composite fibre, first grinding is even, drier under 70-80 DEG C of condition, obtains composite fibre;
(2) tung oil stir process 0.5-1h under 120-150 DEG C of condition is added by after diatomite and talcum powder mixing, stir after mixing with all the other raw materials again, add in the composite fibre in (1), drier process, between moisture control to 8-10%, obtain composite plate base-material;
(3) by the composite plate base-material in (2) through vacuum pneumatic or machinery mat formation shaping, hot pressing, cool, cut, after the process of sanding operation, obtain fire-retardant health fiber composite plate.
Advantage of the present invention is:
The present invention utilizes Silicone acrylic emulsion to improve its intensity and weatherability to fiber material modification, by Ge and nano titanium oxide, to fibrous material, composite modified that material is had is natural antibacterial fungi-proofing, generating negative ions, purify air, remove odor function, again in conjunction with polyvinyl butyral resin, rosin milk, the raw materials such as ZPT composite, the fiber composite plate obtained is made both to have had good mechanical property and weatherability, waterproof and dampproof performance is good, and there is good fungus and mildew resistance effect, sanitation performance is good, be improved body immunity simultaneously, lessen fatigue, get rid of vivotoxin health-care efficacy, peculiar smell can also be removed, purify air, practical.
