Abstract
The present invention discloses a kind of plastic part electrostatic flocking method, includes the following steps：1) fine hair pre-processes：Select appropriate size fine hair, to fine hair carry out dyeing and electricity processing；2) plastic part surface is cleared up；3) plastic part surface sprays the uniform adhesive phase of a layer thickness；4) flocking：Fine hair is positioned in the container of flocking machine, the high-pressure electrostatic produced in flocking machine is output in flocking nozzle, and fine hair is under the action of high-voltage electrostatic field, and vertical glue is sticked in the surface of inside gadget after being sprayed by nozzle；5) fine hair is fixed：Make glue-line drying or crosslinking curing after flocking, fine hair is firmly attached to plastic part surface；It can reach optimal flocking effect according to flocking method provided by the invention.
Description
Technical field
The invention belongs to flocking technology field, is a kind of plastic part electrostatic flocking method specifically.
Background technology
Flocking is to spread fine hair by plant surface scribble adhesive, and fine hair is fixed on by plant after drying or curing
A kind of method on surface, the application range of flocking industrially is wider, and the controlling element of electrostatic flocking technology is more, such as fine hair
Electricity processing, the selection of Electrostatic Control condition etc., it is bad because coordinating between each key element in actual flocking process, often occur as
The problems such as glue splits, burns, influences product quality and appearance.
The content of the invention
In order to solve the above technical problems, the present invention provides a kind of plastic part electrostatic flocking method.
To reach above-mentioned purpose, technological means that the present invention uses for：A kind of plastic part electrostatic flocking method, including it is as follows
Step：
Fine hair pre-processes：Select appropriate size fine hair, to fine hair carry out dyeing and electricity processing；
Plastic part surface is cleared up；
Plastic part surface sprays the uniform adhesive phase of a layer thickness；
Flocking：Fine hair is positioned in the container of flocking machine, the high-pressure electrostatic produced in flocking machine is output to flocking nozzle
Interior, fine hair is under the action of high-voltage electrostatic field, and vertical glue is sticked in the surface of inside gadget after being sprayed by nozzle；
Fine hair is fixed：Make glue-line drying or crosslinking curing after flocking, fine hair is firmly attached to plastic part surface.
Further, the fine hair is nylon-6 and the low-denier fiber of nylon -66.
Further, the length of the villus fiber is in 0.3-3.0mm.
It can reach optimal flocking effect according to flocking method provided by the invention.
Below in conjunction with embodiment, the present invention will be further described in detail.
Embodiment
Flocking is to spread fine hair by plant surface scribble adhesive, and fine hair is fixed on by plant after drying or curing
A kind of method on surface, surface of plastic products pass through flocking, can obtain decoration and the double effects of protection, and the present invention provides a kind of
The electrostatic flocking method of plastic part, includes the following steps：
1) fine hair pre-processes：The fine hair of appropriate size is selected, as nylon-6 and the low-denier fiber of nylon -66, fine hair are fine
The length of dimension in 0.3-3.0mm, fine hair is carried out dyeing and electricity processing so that fine hair has the face of joint product requirement
Color, makes fine hair easily plant plastic part surface in electrostatic field；
2) plastic part surface is cleared up, and physics cleaning method or soak cleaning method can be used to carry out plastic part surface carefully clear
Wash；
3) plastic part surface sprays the uniform adhesive phase of a layer thickness, and adhesive used is epoxy resin, water solubility
Polyvinyl alcohol and Welvic etc., adhesive should ensure that after gluing to not losing good cementability, adhesive before flocking
Viscosity directly influence paste amount, so as to influence flocking fastness indirectly.Viscosity is high, fastness increase, but viscosity is too high, applies
Cloth is not easy uniformly to cause fastness difference.Thickness difference is formed when serious, product has embossing to feel.During high-cycle welding, if being pressed in weakness
Place, fine hair can crack.Perfect condition is before flocking room is entered, and adhesive can pave plastic part base material, viscosity 0.3~
0.35Pas is preferred.In production, when adhesive uses barrel bottom, notice that viscosity increases phenomenon；
4) flocking：Fine hair is positioned in the container of flocking machine, the high-pressure electrostatic produced in flocking machine is output to flocking spray
In head, fine hair is under the action of high-voltage electrostatic field, and vertical glue is sticked in the surface of inside gadget after being sprayed by nozzle；
5) fine hair is fixed：According to the property of adhesive therefor after flocking, make glue-line drying or crosslinking curing after making flocking, make
Fine hair is firmly attached to plastic part surface, and during drying, the temperature gradient that temperature can be used to rise successively is dried, such as
150 °, 160 °, 170 °, 180 °, easy to the curing of adhesive.
Claims (3)
