Wood plastic composite is the modified material obtained with wood materials filling, reinforced plastics, it has both plastics and timber
Major advantage, make the renewable resources such as waste plastic and timber processing waste, contribute to environmental protection and make up the forest reserves
Deficiency is at home and abroad rapidly developed in recent years.Wood materials are mainly made of cellulose, such as wood powder, bamboo powder, shell
There is great amount of hydroxy group functional group on powder etc., its surface, show very strong chemical polarity, to cause wood materials with it is nonpolar
Poor compatibility between plastic substrate, and be easy to reunite consumingly influences powdery wood materials dispersion in the base and multiple
The performance of condensation material.
Invention content
Technical problems to be solved：The object of the present invention is to provide a kind of high-strength light wood plastics tray, energy conservation and environmental protection, machineries
Performance is good, can be used widely.
Technical solution：A kind of preparation method of high-strength light wood plastics tray, includes the following steps：
S1. modified plant fibers：Plant fiber is chopped to 2-5mm, 40-60 mesh sieve is crossed, then washes away surface impurity, dry,
The infiltration of 8mL glacial acetic acids, microwave activation process 4-8min, microwave power 200-400W is added, taking-up is cooled to room temperature, is added
6mL acetic anhydrides, the 1 drop concentrated sulfuric acid, stir evenly, until carrying out esterification in micro-wave oven, wash and dry after reaction；
S2. following component is weighed by weight：70-100 parts of high density polyethylene (HDPE), 40-65 parts of modified plant fibers, white carbon
10-20 parts, 0.1-0.5 parts of polyethylene wax, 0.5-1 parts of calcium stearate, 0.8-2 parts of fire retardant, antioxidant 168 is 0.5-1 parts,
20-30 parts of reinforcing agent, 1-3 parts of ethylenebisstearamide；
S3. high density polyethylene (HDPE) heating is melted, residual components is then added and are uniformly mixed at 165 DEG C, thin logical rear slice；
S4. finally preheat 5 min, 4 min of pressurize, 15 MPa of pressure at 170 DEG C, after mould unloading on cold plate 6 min of pressurize,
16 MPa of pressure.
Further, fabric fibre is any in abaca or coir in the step S1.
Further, reinforcing agent is in modified alkyl phenolic resin or ethylene-vinyl acetate copolymer in the step S2
It is any.
Further, in the step S2 fire retardant be decabromodiphenylethane and zinc borate mixture.
Further, following component is weighed by weight in the step S2：80-90 parts of high density polyethylene (HDPE), it is modified to plant
45-60 parts of fibres, 10-15 parts of white carbon, 0.2-0.4 parts of polyethylene wax, 0.6-0.8 parts of calcium stearate, fire retardant 1-1.6
Part, antioxidant 168 is 0.5-0.8 parts, 24-28 parts of reinforcing agent, 2-3 parts of ethylenebisstearamide.
Advantageous effect：The present invention's has the following advantages：
1, modified alkyl phenolic resin and ethylene-vinyl acetate copolymer are more preferable to the surface compatibility of plant fiber, mainly
Phenolic resin and ethylene-vinyl acetate copolymer intramolecular contain more polar functional group, pass through soda acid phase with fiber surface
Interaction forms stronger bonding, while it can form a degree of molecular entanglement with plastic molecules again；
2, coir and abaca fibre are a kind of plant fiber of resource compared with horn of plenty, and toughness value is larger, cheap
Plant fiber, directly with polyethylene compatible if interface compatibility it is poor, after being modified compatibility improve, while addition change
Property plant after, since the addition of fiber helps to transmit the stress between matrix and fiber, enhancing is played to matrix itself and is made
With.
