Abstract
The invention discloses a waterproof, corrosion-resistant and health-care fiber composite board. The waterproof, corrosion-resistant and health-care fiber composite board is characterized by being manufactured from, by weight, 40-60 parts of rice straw, 20-30 parts of palm fibers, 10-15 parts of rice hull ash, 3-5 parts of high aluminum powder, 10-15 parts of a urea-formaldehyde resin adhesive, 2-4 parts of bis-hydroxyethyl terephthalate, 4-8 parts of a silicone acrylic emulsion, 4-6 parts of a carnauba wax emulsion, 4-8 parts of composite nanometer suspension and 2-4 parts of epoxidized soybean oil. The fiber composite board has good mechanical properties and weather resistance and high waterproof and corrosion-resistant performance. Meanwhile, the fiber composite board has the health-care effects of improving the immunity of the human body, alleviating fatigue and eliminating toxins in the human body. The fiber composite board can also be used for removing peculiar smell and purifying air, and is high in practicality.
Description
Technical field
The present invention relates to composite board field, be specifically related to a kind of water-fast corrosion-resistant 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 water-fast corrosion-resistant 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 water-fast corrosion-resistant health fiber composite plate, it is obtained by the raw material of following weight parts:
Rice straw 40-60, monkey grass 20-30, rice hull ash 10-15, high-alumina fly 3-5, urea-formaldehyde resin adhesive 10-15, ethylene glycol terephthalate 2-4, Silicone acrylic emulsion 4-8, Brazil wax emulsion 4-6, composite Nano suspension 4-8, epoxidized soybean oil 2-4;
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 water-fast corrosion-resistant health fiber composite plate, comprises the following steps:
(1) pulverize through pulverizer after rice straw and monkey grass is clean, drying, obtain composite fibre; Again Silicone acrylic emulsion, Brazil wax emulsion and composite Nano suspension 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) will rice hull ash and high-alumina fly mixing after add epoxidized soybean oil and under 120-150 DEG C of condition stir process 0.5-1h, 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 rice hull ash, high-alumina fly, ethylene glycol terephthalate, epoxy soybean wet goods raw material composite, the fiber composite plate obtained is made both to have had good mechanical property and weatherability, water-fast decay resistance is strong, there is raising body immunity simultaneously, lessen fatigue, get rid of vivotoxin health-care efficacy, peculiar smell can also be removed, purify air, practical.
Detailed description of the invention
Non-limiting examples of the present invention is as follows:
A kind of water-fast corrosion-resistant health fiber composite plate, is prepared from by the component raw material of following weight (kg):
