Description
Technical field
The invention mainly relates to the technical fields of particieboard processing, and in particular to the particieboard of multilayer environment protecting type processes work
Skill.
Background technology
Particieboard is called particle board, particle board, bagasse board, the particle made of timber or other ligno-cellulosic materials,
Apply the wood-based plate composed under heating power and pressure effect after adhesive, also known as flakeboard；Because wood shavings harden structure is more equal
Even, processing performance is good, can be processed into the plank of large format as needed, is that make different size, the furniture of pattern preferable
Raw material.It is mainly used for Furniture manufacture and building industry and train, automobile bodies manufacture.
Existing particieboard in the market, and particieboard is since plate thickness is larger, can generally be used for making dining table, bed etc.
Furniture, but the content of formaldehyde in particieboard is very high, can be damaged to human body, induces a variety of human body diseases.
It based on this, needs to develop a kind of particieboard of bottom content of formaldehyde in the market, to meet in actual life, people are to strong
The pursuit of health.
Invention content
Invention broadly provides the wood shavings board machining process of multilayer environment protecting type, to solve to propose in above-mentioned background technology
, existing particieboard content of formaldehyde is high, and the technical issues of affect health.
The present invention solve the technical solution that uses of above-mentioned technical problem for：The wood shavings board machining process of multilayer environment protecting type, packet
Particieboard ontology is included, the ontology is equipped with upper epidermis, purifying layer, heath care layer and layer successively from top to bottom；The upper table
Layer and layer are to be formed by upper table laminate and following table laminate, and in the food ingredient of the upper table laminate and following table laminate, wrap
Include following raw material：Stalk particle, fire retardant, first adhesive and a small amount of water, wherein three fourth of phosphoric acid of fire retardant
Ester, triazine and its compound and trichlorobromomethane and octabromodiphenyl chloride；The purifying layer be by the first compression plate embryogenesis,
The first compression plate embryo includes following raw material：Stalk particle, ivy, aloe, green flower bud, Commeline communis, second adhesive and few
Measure water；The heath care layer is formed by the second compression plate, and second compression plate includes following raw material：Stalk particle, wormwood, musk deer
Fragrant, second adhesive and a small amount of water.
Preferably, each ingredients by weight part in the upper epidermis and layer is 10-15 parts of stalk particles, 0.5-1 parts of resistances
Agent, 1-2 parts of first adhesives and 0.1-0.3 parts of water are fired, each ingredients by weight part in the fire retardant is 0.2-0.4 parts of tricresyl phosphates
Butyl ester, 0.1-0.2 part triazine and its compound and 0.2-0.4 parts of trichlorobromomethanes and octabromodiphenyl chloride, described first is viscous
Mixture is Lauxite or phenolic resin.
In above-mentioned preferred technical solution, the formula in fire retardant includes tributyl phosphate, triazine and its compound
With trichlorobromomethane and octabromodiphenyl chloride, wherein three kinds of compounds are fire retardant, wherein triazine and its compound exist
When exclusive use, flame retardant effect is undesirable, but when coordinating tributyl phosphate, can realize facilitation effect, when plank is heated,
Tributyl phosphate can generate the more stable crosslinking shape solid matter or carburization zone of structure, on the one hand the formation of carburization zone can hinder
Only polymer is further pyrolyzed, and the thermal decomposition generation that it on the other hand can be prevented internal enters gas phase and participates in combustion process, together
When, by triazine and its synergism of compound, the formation for being crosslinked shape solid matter or carburization zone can be promoted, further
Promote flame retardant effect；Meanwhile trichlorobromomethane and octabromodiphenyl chloride belong to halogen containing flame-retardant, its evaporating temperature and polymerization
Object decomposition temperature is same or similar, and when polymer is thermally decomposed, fire retardant also evaporates simultaneously, at this time halogen containing flame-retardant with
Thermal decomposition product is in gas-phase combustion area simultaneously, and halogen just can capture the free radical in combustion reaction, interfere the chain of burning anti-
It should carry out, to be assisted by the mixing of three kinds of fire retardants, the flame retardant effect for realizing plank can be maximized.
Preferably, each ingredients by weight part in the first compression plate embryo be 10-15 part stalk particles, 0.1-0.2 parts it is normal
Spring rattan, 0.05-0.1 portions of aloes, 0.05-0.1 parts of green flower buds, 0.1-0.2 parts of Commeline communis, 1-2 parts of first adhesives and 0.1-0.3 parts
Water, each ingredients by weight part in the second compression plate embryo are 10-15 parts of stalk particles, 1-2 parts of wormwoods, 0.01-0.02 portions of musk deers
Fragrant, 1-2 second adhesives and 0.1-0.3 parts of water, the second adhesive are green frog non-toxic herb glue.
In above-mentioned preferred technical solution, in wood shavings harden structure, pass through stalk particle, ivy, aloe, green flower bud and duck
It opens up grass and the first compression plate embryo is made, can not only realize the formaldehyde of the particieboard ontological existence, meanwhile, it can also absorb that there are the wood shavings
The formaldehyde of plate surrounding plays the purpose of scavenging air；Meanwhile ivy, aloe, green flower bud and Commeline communis are all the plants for absorbing formaldehyde
Object, not only cultivation is convenient, but also of low cost, reduces the processing cost of particieboard；Further, green frog non-toxic herb glue is
The nontoxic biological glue of Shenzhen green frog biology Co., Ltd invention breaks the whole world more than 150 years without containing harmful substances such as formaldehyde, benzene
That comes makes the history of glue using formaldehyde as main component, obtains countless special honours, the Grand Prix of most component is：The United Nations issues
" whole world green new product Grand Prix ", this scientific and technological achievement is taken the lead in applying to Olympic Games Bird's Nest, Grand National Theatre, Shanghai generation
Zero carbon shop of rich meeting；By the effect of green frog non-toxic herb glue, not only under conditions of not influencing plank internal material viscosity, can drop
The side effect that low plank formaldehyde is poisoned.
