Description
【Technical field】
The present invention relates to sawdusts to recycle processing technique field, and in particular to a kind of to discard sawdust production composite plate with oak
Method.
【Background technique】
Oak category Quercus acutissima, in yellowish-brown to reddish brown, growth ring is obvious for oak pith, slightly corrugate, and oak density is big, quality heavily fortified point
Firmly, slow-drying is widely used in decoration lagging material and production fat.With the enhancing of world's environmental consciousness and the felling to forest
It is restricted, increasingly increasing to timber-work demand in people's life, exists to the recycling industry of sawdust but then
It has a vast market foreground and economic benefit.
【Summary of the invention】
Goal of the invention of the invention is：In view of the above problems, one kind is provided, sawdust production is discarded again with oak
The method of plywood, this method can make full use of oak sawdust, and the composite plate intensity obtained by processing is high, elasticity is good, not contain
Evil substance, use are safe.
To achieve the goals above, the technical solution adopted by the present invention is as follows：
A method of sawdust production composite plate is discarded with oak, is included the following steps：
S1：Oak sawdust is put into pulverizer and is crushed, is placed into wood dust dryer, in 105~110 DEG C of temperature
Under the conditions of dry 4~6h；Sawdust after drying is subjected to sieving screening, partial size is that 4~5mm is level-one sawdust, 2~4mm of partial size
Being lower than 2mm for second level sawdust, partial size is three-level sawdust；
S2：Choose 30~35 parts of level-one sawdust, 10~12 parts of second level sawdust, 4~9 parts of three-level sawdust and binder 15~18
Part, above-mentioned raw materials are put into blender and are stirred, mixed raw material is obtained；
Wherein, the binder includes the raw material components of following parts by weight：52~55 parts of high density polyethylene (HDPE), polyvinyl alcohol
6~9 parts, 1~1.5 part of dibenzothiazyl disulfide, 2~3 parts of maleic anhydride, 2~2.2 parts of glycerine, white carbon black 3~5
Part；
S3：Above-mentioned mixed raw material is added in molding die, is sent into panel hot press and is suppressed, in 150~155 DEG C
At a temperature of carry out 10~15min of heat cure, then release, die sinking, carry out polishing repairing type after taking-up, on its surface uniformly
It dries after spraying underwater paint to get the composite plate is arrived.
Further, in step sl, the water content after the oak sawdust is dry is 14~15%.
It further, is to choose 32 parts of level-one sawdust, 11 parts of second level sawdust, 6 parts of three-level sawdust and binder in step S2
16 parts, above-mentioned raw materials are put into blender and are stirred, obtains mixed raw material.
Further, in step s 2, the binder includes the raw material components of following parts by weight：High density polyethylene (HDPE) 54
Part, 8 parts of polyvinyl alcohol, 1.2 parts of dibenzothiazyl disulfide, 2.5 parts of maleic anhydride, 2.1 parts of glycerine, 4 parts of white carbon black.
Further, in step s 2, the production method of the binder is：The raw material investment of formed binder is anti-
It answers in kettle, and after being heated with stirring to 105~108 DEG C, continuously stirs 20~30min.
Further, in step s 2, the specific surface area of the white carbon black is 148~155m2/g。
The present invention provides it is a kind of with oak discard sawdust production composite plate method, compared with prior art, have with
Lower beneficial effect：
The present invention is that oak sawdust is put into pulverizer to crush, and places into drying in wood dust dryer, will dry
Sawdust afterwards carries out sieving screening, in binder in sufficiently stirring in blender after the sawdust after screening is matched according to different-grain diameter
It mixes uniformly, it is last hot-forming, then carry out after polishing repairing type to get to the composite plate.Wherein, oak sawdust of the present invention
This part resource is re-used from wastes, the present invention such as processing leftover pieces, afterproduct recycling, can not only solve to give up
The handling problems of gurry, turn waste into wealth, and realize rationally recycling for resource, avoid the waste of resource.
Sawdust after drying is carried out classification processing according to particle size by the present invention, rational proportion process raw material in difference
The proportion of partial size sawdust while energy saving, can make the even density of gained composite plate, quality firm, resistance to compression folding endurance energy
More preferably；The present invention is also added by high density polyethylene (HDPE), polyvinyl alcohol, dibenzothiazyl disulfide, maleic anhydride, the third three
The combination of binder made of alcohol, white carbon black, this binder is safe and harmless, can merge very well between sawdust, has stronger
Cohesive force, thus enhance gained composite plate intensity and elasticity.Each technological means of the present invention is all phase interworking
It closes, mutually promote, and camp step by step, is all linked with one another, generated total technical effect is significantly larger than single technological means
The simple adduction of generated technological means.
In short, the present invention provides a kind of method for discarding sawdust production composite plate with oak, this method can make full use of rubber
Sawdust, the composite plate intensity height obtained by processing, elasticity is good, is free of harmful substance, and use is safe.
