Abstract
The invention discloses a method for producing smokeless flameproof wooden artificial plate, comprising that using breaker to break the flameproof powder, adding flameproof powder into wooden artificial adhesive while its mass percentage is 5-30% of solid adhesive, then using relative solidifier to adjust the pH value of adhesive to normal value, using general adhesive to produce the artificial plate. The invention has low cost and the strength reaching national standard, while the inventive product will not smoke and burn at 500-700Deg. C.
Description
Technical field
The present invention relates to a kind of manufacture method of fumeless flame-retardant wood-based plate, specifically, relate to a kind of make at 500-700 ℃ following decompose and degrade, do not smolder, incombustible wood-base fibre and particle panel material manufacture method.
Background technology
Wood materials solves the topmost approach that its high-quality and high-efficiency utilizes problem just in the extensive utilization in building and interior decoration field.In recent years, along with China's rapid economy development, the progressively improvement of the raising of national income and living standards of the people, building and interior decoration are ascendant trend year by year with the consumption of wood materials.At present, annual 8000 ten thousand steres that surpass of the utilization of wood materials aspect building and interior decoration.Particularly in recent years, the Chinese government begins to introduce timber buildings advanced manufacturing technology and equipment from developed countries such as America and Europe, Japan, promoted the development of China's timber buildings more apace, the wood materials consumption figure increases progressively just with surprising rapidity, yet has also increased the fireproof potential safety hazard simultaneously greatly.Because the wood materials easy firing particularly discharges a large amount of poison gas in the burning, causes great casualties and property loss, according to the fire statistics analysis, in the fire incident of countries in the world, building fire accounts for the first place, and 35% relevant with fibers such as timber, fabrics in the building fire; And, though the fire cause is different, intensity of a fire expansion, casualties etc. all with the building interior decoration in a large amount of flammable combustible materials such as wood materials that use direct relation is arranged.Therefore, the fire-retardant research of wood materials has caused the extensive concern of countries in the world.Though obtained many scientific achievements in this research field, fundamentally do not solved the problem of not burning He not being fuming of wood materials so far.Though timber is a kind of flammable material that has, and utilizes flame-retarded technology, can make its application more extensive, makes construction and decoration greatly improve with the fire savety of timber.Just be based on pressing for of present situation and reality, applicant of the present invention carries out system research to wood-base fibre and particle panel material is fire-retardant, has found the Changing Pattern of the smokeless carbonization of wood-base fibre and particle panel material.The acquisition of this achievement in research will realize that wood-base fibre and particle panel material does not burn and is not fuming under 500-700 ℃, be expected to allow the mankind away from fire, ensures the people's safety of life and property conscientiously.
Summary of the invention
The present invention wants the technical solution problem to provide a kind of fumeless flame-retardant wood-based plate manufacture method, realizes that wood-base fibre and particle panel material does not burn under 500-700 ℃ and is not fuming.
In order to solve the problems of the technologies described above, the manufacture method of the fumeless flame-retardant wood-based plate that the present invention adopts, adopt following steps:
(1), fire retardant powder preparation: utilize pulverizer that fire retardant is processed into maximum particle diameter and be not more than 10 purpose powder;
(2), adhesive allotment: adding quality in the wood-base fibre and particle panel material adhesive is the fire retardant powder of the 5-30% of adhesive over dry solid masses, adopt corresponding curing agent that the Ph value of adhesive is adjusted to normal value then as required, adopt the technology of utilizing adhesive to produce wood-based plate commonly used to make wood-based plate.
Fire retardant described in the above-mentioned steps (1) is meant perlite.
The maximum order number of powder described in the above-mentioned steps (1) is not more than 10 orders.
Wood-base fibre and particle panel material adhesive described in the above-mentioned steps (2) comprises urea-formaldehyde resin adhesive, milky white adhesive, PUR, epoxyn, synvaren, melamine resin adehsive stick or isocyanate resin adhesive, and their modified products and mutually mixed product.
Fumeless flame-retardant wood-based plate manufacture method provided by the invention, wood-base fibre and particle panel material comprises with timber being all kinds of sheet materials that raw material is produced, easy to operate, be easy to realize, the manufacturing intensity of wooden artificial panel meets or exceeds national standard, and the wood-base fibre and particle panel material that what is more important utilizes this invention to produce can not smoldered under 500-700 ℃ of condition and do not burnt.The present invention not only can improve the general safety function in municipal public safety security system and city, and be expected to make human away from fire, particularly resist fire performance to improving national defense facility, increase the timber added value, increase farmers' income, build a harmonious society significant.This invention can produce remarkable economical and social benefit, have excellent popularization and be worth.
