Description
Technical field
The invention belongs to tea table manufacturing technology field, and in particular to a kind of system of wood plastic composite for tea table manufacture
Preparation Method.
Background technology
Tea table is life appliance essential in modern people's family life, primarily serves and places teacup, fruit tray, vase
Deng the effect of object.The material of traditional tea table is solid wood board, and its shortcoming is that weight is big, heavy, while is also easily damaged by worms, mould corruption
Erosion.Simultaneously as destruction of the people for natural resources, the quantity of trees are greatly reduced, also require that people can not abuse timber.
Wood plastic composite is to carry out mixing hot pressing by wood powder and high polymer material forming, which not only reduces the usage amount of timber, together
When can also reduce overall quality, and be easy to process, overall manufacturing cost is relatively low, and specious, has and pushes away well
Wide use value.
Although wood plastic composite has good use characteristic, because containing substantial amounts of polar functional group in wood powder, tool
There is hydrophily, and high polymer material is mainly made up of nonpolar molecule, therefore cause interface compatibility between the two poor, it is overall
Mechanical property it is bad, in order to lift overall use characteristic, need badly and above mentioned problem be improved.
The content of the invention
The purpose of the present invention is to be directed to the problem of existing, there is provided a kind of system of wood plastic composite for tea table manufacture
Preparation Method.
The present invention is achieved by the following technical solutions：
A kind of preparation method of wood plastic composite for tea table manufacture, comprises the following steps：
（1）Wood powder processing：
A. wood powder is put into60Taken out in Co- gamma-ray irradiation instrument after 15 ~ 20min of radiation treatment standby；
B. the wood powder after a is handled will be operated to put into modification liquid immediately, it is 90 ~ 95 DEG C that heating, which keeps the temperature of modification liquid, leaching
Taken out after 30 ~ 35min of bubble processing standby；Each composition and its corresponding parts by weight are in the modification liquid：20 ~ 25 parts of acetic anhydrides, 1 ~ 3
Part rare earth nitrades, 100 ~ 110 parts of water；
C. it will operate to be immediately placed in household freezer after the wood powder after b is handled filters out and carry out freezing processing, take out and be put into after 2 ~ 3h
Processing is dried in freeze drier, drying to overall water content is taken out standby after being not more than 5%；
（2）Mixing and molding：
By step（1）Wood powder after processing is with high density polyethylene (HDPE) according to mass ratio 1：2 ~ 2.5 are mixed, and are then placed in mixed
Practice 20 ~ 25min of mixing process in machine, placed into after taking-up hot-forming in vulcanizing press.
Further, step（1）Operate described in a60The accumulated dose of Co- gamma-ray irradiations is 5 ~ 7kGy.
Further, step（1）It is also constantly right with 400 ~ 500 revs/min of rotating speed during the immersion treatment described in b to operate
Modification liquid is stirred.
Further, step（1）It is any in lanthanum nitrate, cerous nitrate, ytterbium nitrate to operate the rare earth nitrades described in b
It is a kind of.
Further, step（1）The temperature for operating the freezing processing described in c is -20 ~ -25 DEG C.
Further, step（2）Described in mixing process when temperature control be 150 ~ 160 DEG C.
Further, step（2）Described in hot pressing temperature be 170 ~ 175 DEG C, the pressure of hot pressing be 8 ~ 10MPa, guarantor
When a length of 15 ~ 20min of pressure.
In order to improve the synthesis mechanical characteristic of wood plastic composite, existing multipair wood powder composition carries out surface modification treatment, right
It is one of wherein relatively conventional method that wood powder, which carries out esterification treatment to be modified, and its principle is wood powder fiber surface to occur esterification instead
Should, improve the surface-active of wood powder, lifted the compatible associativity between macromolecule raw material, but be to use second the problem of this mode is present
Anhydride solution carries out that during esterification treatment substantial amounts of acetic acid can be produced, although acetic acid can promote the progress of esterification, simultaneously can
Wood-fibred is degraded, destroys the structure of wood-fibred, have impact on overall mechanical strength, present invention improves in wood moulding to this
To the modification processing method of wood powder in composite manufacture, wherein first being carried out to wood powder60The processing of Co- gamma-ray irradiations, this behaviour
Work can effectively activate the surface-active of wood powder fiber, lift its activity group content, can accelerate the hydroxyl-functional of wood powder fiber
Group and the displacement of the acetyl group in solution of acetic anhydride, at the same the rare earth nitrades added in modification liquid can catalysed promoted esterification instead
The process answered, with60The processing collaboration of Co- gamma-ray irradiations improves the process of esterification, reduces the growing amount of acetic acid, and can
Effectively reduce the heating-up temperature needed for esterification modification（It is in existing method to need to be kept for more than 110 DEG C more）, equally decrease acetic acid
Growing amount, and degraded destructiveness of the acetic acid to wood powder fiber is reduced, beneficial to the holding of mechanical characteristic, afterwards again to esterification
Modified wood powder has carried out freezing and drying process, and in esterification, the oh group in wood powder is instead of because of acetyl group,
So as to which creating inflation effect so that the volume increase of wood-fibred, and the intensity of wood-fibred and the length of fiber, wall thickness etc.
There is significant correlation, therefore esterification modification reaction can lift the mechanical characteristic of wood powder fiber to a certain extent, and be generally esterified anti-
Ying Houhui directly the wood powder after esterification is dried processing, and the either physical arrangement of the fiber after being just esterified or chemistry are special
Property it is unstable, be directly dried processing easily cause inflation effect damage, also just reduce to wood powder fiber mechanicses characteristic
The effect of lifting, the present invention directly carry out freezing processing to wood powder after esterification, and low-temperature treatment can consolidate esterification well
Modified effect, the freeze-drying process then carried out can avoid traditional heated drying processing moisture change from producing punching to wood powder fiber
The problem of hitting stress, it further avoid it and the damage of effect inflated to esterification, improve the use characteristic of wood powder.
The present invention has advantages below compared with prior art：
The present invention has carried out special modification to the wood powder in wood plastic composite, effectively improves its composite filled effect
Fruit, the mechanics of final obtained wood plastic composite are significantly improved using characteristic, and it is made the synthesis of tea table and obtained using quality
Effective enhancing, has good value for applications.
