Abstract

The invention discloses a process for manufacturing an integral fireproof door by utilizing wheat stalks and peanut shells and a manufacturing method for the integral fireproof door. The integral fireproof door is manufactured by the following procedures of: crushing main raw materials of the wheat stalks and the peanut shells, performing vacuum pressurization treatment by using a JLAI wood flame retardant solution at the concentration of not more than 30 percent, mixing and hot forming by using a terminated polyurethane adhesive not containing formaldehyde completely as an adhesive, microcrystalline chlorinated paraffin as a functional agent and mountain flour as a filler, and the like. The integral fireproof door has a dual function of flame retardancy and corrosion resistance; and the process effectively changes the combustion performance of the stalks. Beside the flame retardancy, the integral fireproof door can effectively prevent harm of various bacteria and worms to the door, and the service life of the fireproof door is greatly prolonged. Moreover, toxic and harmful chemical substances such as formaldehyde and the like are not released, the harm to a human body is avoided, and the fireproof door becomes a real green fireproof door.

Description

Utilize wheat stalk, Pericarppium arachidis hypogaeae to make whole fire door technology and method of manufacture thereof

Technical field

The present invention relates to a kind of technical field of agricultural stalk comprehensive utilization, refer to especially utilize wheat stalk, Pericarppium arachidis hypogaeae to make whole fire door technology and method.

Background technology

Be accompanied by the fast development that China's economic is built, high-rise and baroque big area tier building emerge in multitude.Modern architecture has generally been installed fire door according to national regulation.Fire door is a kind of active fire-resisting division thing, and it has more the effect that stops fire spreading and Flue Gas Diffusion except that the effect with common door, can stop spreading of the intensity of a fire within a certain period of time, guarantees evacuating personnel.Set fire door except that the effect that possesses common door, also have the specific function of fire-proof smoke insulation.During presence of fire, with the protection safety evacuation vital role is arranged for suppressing fire spreading.At present; Fire door on the market mostly is that wooden process is handled making, yet fire-proof wooden door receives the restriction of timber space structure when fire retardant is handled; It is inner that liquid is difficult to penetrate into most timber, and therefore most timber are difficult to carry out the flame-retardant impregnating processing.After the fire-retardant finish, timber and wood-based plate intensity reduce by 15～40% in addition, have influenced the problems such as quality of product, and particularly current timber resources scarcity has also had a strong impact on production.

Not only have the toughness of timber and utilize agricultural stalk to make fire door, and the hard timber that also beats by miles of quality, anti-folding had, the shock resistance characteristics.Low production cost, except fire-proof function, it has also possessed functions such as moistureproof, corrosion-resistant, heat insulation, sound insulation, and more estimable is, and the stalk invention cannot not have agingly, and indeformable, mouse bite preventing is damaged by worms, and is durable in use, and this is that many timbers all can't match in excellence or beauty with it.

Summary of the invention

It is main raw material that the present invention mainly adopts wheat stalk, Pericarppium arachidis hypogaeae; Through pulverizing; Must not carry out vacuum pressed greater than 30% JLAI fire-retarding of wood agent solution with concentration handles; Use the end envelope urethane adhesive do not contain formaldehyde fully as tackiness agent, the crystallite clorafin is made functional agent, and stone flour is made weighting agent and is made through mix, operation such as hot-forming; The fire door that the present invention makes is a kind of fire door fire-retardant, anticorrosion dual performance that has concurrently, and this fire door technology has changed the combustionproperty of stalk effectively.Except that flame retardant properties, but also can prevent the harm of multiple bacterium, worm effectively, greatly prolong the work-ing life of fire door fire door.And do not have toxic and harmful substance releases such as formaldehyde yet, human body is not had harm, can deserve to be called real green fire door.

To achieve these goals, technical solution of the present invention is: the first step, wheat stalk is removed the defoliation grass, and with the mixed of Pericarppium arachidis hypogaeae, become particle with kibbler according to 40: 60; Second goes on foot, and the JLAI wood fire retardant is mixed with the aqueous solution of concentration 20%～30%; The 3rd step, wheat stalk of pulverizing and Pericarppium arachidis hypogaeae compound to be packed into flood in the vacuum pressed jar, pressure is 1.5MP～2.0MP, suppresses 12h; In the 4th step, adopt air-flowing type drying side and cylindrical drier to carry out drying; In the 5th step, dried feed and stone flour, crystallite clorafin, end envelope urethane adhesive glue are mixed in proportion; In the 6th step, carry out hot pressing with 200 tons of four-column universal hydraulic presses with being filled in the compound after the applying glue in the mould; In the 7th step, overpainting or hot pressing laminating machine carry out pad pasting as required, assemble again behind the fire door accessory finished product.

The practical implementation method

1, prescription:

Pericarppium arachidis hypogaeae ... 30%, wheat stalk ... 25%, JLAI wood fire retardant ... 15%, stone flour ... 16%, end envelope urethane adhesive ... 12%, crystallite clorafin ... 2%.

2, technical process:

Pericarppium arachidis hypogaeae, wheat stalk-pulverizing-dipping-drying-filler mixing application-dress mould hot pressing-japanning overlay film-assembling fire prevention accessory-finished product.

3, method of manufacture

1., pulverize: it is careless that wheat stalk is removed defoliation, with the mixed of Pericarppium arachidis hypogaeae according to 40: 60, that the particle of pulverizing the 0.5～1.0mm that grows up is for use;

2., flame retardant solution preparation: the aqueous solution that the JLAI wood fire retardant is mixed with concentration 20%～30%;

3., dipping: wheat stalk of pulverizing and Pericarppium arachidis hypogaeae compound are packed in the vacuum pressed jar, and with the retardant solution dipping, pressure is 1.5MP～2.0MP, and normal temperature is suppressed 12h;

4., drying: adopt air-flowing type drying side and cylindrical drier that the raw material that dipping finishes is carried out drying, drug loading reaches 45～60kg/m behind the impregnation drying ³Get final product;

5., mix: Pericarppium arachidis hypogaeae, wheat stalk mixing particle, stone flour, end envelope urethane adhesive, crystallite clorafin be uniform mixing in mixing machine in proportion;

6., dress mould hot pressing: on mould, spray one deck wax pattern releasing agent earlier; With being filled into respectively in the compound after the applying glue in the mould, carry out hot pressing with 200 tons of four-column universal hydraulic presses again, hot pressing temperature is controlled at 150-200 ℃; Hot pressing pressure is at 2～3.5Mpa, and hot pressing time is 30-60 second;

7. membrane processing: can carry out grinds by standard-required opposite house limit after the depanning; Because of promptly carrying wood grain behind the membrane, can copy various famous and precious seeds and directly paint, the graceful nature of its texture such as timber; Texture is true to nature various, beech, oak, teak, maple, kirch, Cortex Fraxini mandshuricae or the like! Also can cover methods such as PVC decorating film as required with the moulding facing machine, at last behind the assembling fire prevention accessory finished product.

The above; Practical ways only is that preferred implementation of the present invention is described; Be not that scope of the present invention is limited; Under the prerequisite of the spirit that does not break away from the present invention's technology, various distortion and improvement that this area engineering technical personnel make technical scheme of the present invention all should fall in the definite protection domain of claims of the present invention.
