Abstract
The present invention is a kind of preparation process of bamboo-plastic packaging box base, is comprised the step of: 1) being controlled the water content of bamboo fibre within 1% using microwave dryer；2) bamboo fibre, resin, inorganic filler and other auxiliary agents are first proportionally added into high-speed mixer to stir to 100 DEG C, place into cold mixing pot and continues to stir, lubricant is added when temperature is down to 40 DEG C and stirs 5min, it is spare.A kind of preparation process of bamboo-plastic packaging box base of the present invention, easy to operate, convenient, product quality obtained by production is higher.
Description
Technical field
The present invention relates to packing box field more particularly to a kind of preparation processes of bamboo-plastic packaging box base.
Background technique
Bamboo is a kind of gramineae plant, has the excellent characteristics such as growth cycle short, fibre strength is high, antibacterial, acid and alkali-resistance.Bamboo
Plastic composite materials be using bamboo fibre be main reinforcing filler, thermoplastic resin as matrix, it is compound by high temperature and pressure melting mixing
Made of a kind of energy saving and environment friendly composite material.Under petrochemical industry resource and the status of forest reserves worsening shortages, using height
It fills bamboo-plastic composite material and replaces traditional plastic cement and solid wood material, can not only obtain excellent mechanical property, and will not be right
Ecological environment damages, and has very important realistic meaning.
Be added in thermoplastic resin after not melting insoluble bamboo fibre, microstructure and processing rheological behavior have occurred compared with
Big variation.During machine-shaping, bamboo fibre exists in solid form always, the physics generated under heated pressure
Chemical reaction is complicated, can release some unstable chemical substances, increases so as to cause viscosity, poor processability, even
Melt fracture can be caused because of the release of plant fiber internal junction Heshui.
Therefore, the high filling bamboo-plastic composite material moulding process of tradition is mostly extrusion molding, i.e., squeezes out by conical double-screw
The powerful axial thrust of machine, by composite material extrusion forming.It can be reduced due to composite fluidity difference in this way to production equipment
With the requirement of technique.But extrusion moulding product is profile, structure is single, can not for complicated special-shaped packing box class product
Realize one-pass molding.Although occurring a small number of new processes being molded for bamboo-plastic composite material with molding machine-shaping in recent years,
But plant fiber content is lower in this kind of composite material.
For this purpose, designing a kind of preparation process of bamboo-plastic packaging box base, problem above is solved.
Summary of the invention
The present invention is to overcome the above deficiency, provides a kind of preparation process of bamboo-plastic packaging box base, comprises the step of:
1) water content of bamboo fibre is controlled within 1% using microwave dryer；
2) bamboo fibre, resin, inorganic filler and other auxiliary agents are first proportionally added into high-speed mixer to stir to 100 DEG C,
It places into cold mixing pot to continue to stir, lubricant is added when temperature is down to 40 DEG C and stirs 5min, it is spare；
3) equidirectional parallel double-screw extruder extruding pelletization, extruding granulator 1- is added in the material mixed by step 2
The temperature in 10th area is respectively 150,170,180,190,190,190,180,190,180,175 DEG C；It is granulated line and uses the big mouth mold of 5mm
Pellet head, and the air-cooled tie rod of steel band and gantry pellet device are configured, to guarantee that particle is closely knit, uniform；
4) before use, bamboo-plastic composite material particle is dried at 100 DEG C, the time is no less than 3h, is then infused by mold
It is moulded into type, molding bamboo-plastic packaging box base thickest is 9mm.
The beneficial effects of the present invention are:
A kind of preparation process of bamboo-plastic packaging box base of the present invention, easy to operate, convenient, product obtained by production
Quality is higher.
Specific embodiment
It is described in detail below with reference to the embodiment of the present invention.
A kind of preparation process of bamboo-plastic packaging box base, comprises the step of:
1) water content of bamboo fibre is controlled within 1% using microwave dryer；
2) bamboo fibre, resin, inorganic filler and other auxiliary agents are first proportionally added into high-speed mixer to stir to 100 DEG C,
It places into cold mixing pot to continue to stir, lubricant is added when temperature is down to 40 DEG C and stirs 5min, it is spare；
3) equidirectional parallel double-screw extruder extruding pelletization, extruding granulator 1- is added in the material mixed by step 2
The temperature in 10th area is respectively 150,170,180,190,190,190,180,190,180,175 DEG C；It is granulated line and uses the big mouth mold of 5mm
Pellet head, and the air-cooled tie rod of steel band and gantry pellet device are configured, to guarantee that particle is closely knit, uniform；
4) before use, bamboo-plastic composite material particle is dried at 100 DEG C, the time is no less than 3h, is then infused by mold
It is moulded into type, molding bamboo-plastic packaging box base thickest is 9mm.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications are also answered
It is considered as protection scope of the present invention.
