Abstract
The invention relates to a coating process method applied to plastic production equipment and discloses an environment-friendly and energy-saving coating process method. The coating process method comprises the following steps: (1) starting to draw a plastic film through a plastic double-drawing machine; (2) horizontally drawing the plastic film through the plastic double-drawing machine; (3) during horizontal drawing, coating the horizontally-drawn plastic film with an aqueous solvent; and (4) stabilizing the tension of the coated film after drawing, namely performing sizing operation, and drying a coating. According to the coating process method, the film is coated with the aqueous solvent before being horizontally drawn and sized, so that gas harmful to a human body and the environment cannot be emitted; meanwhile, the coating is dried at high temperature of 200-250 DEG C reached during sizing operation. Through an experiment, the drying effect is quite good, the coating drying and the sizing operation are almost performed simultaneously, so that a great amount of electric energy is saved, and the beneficial effects of environmental protection and energy conservation can be achieved.
Description
Technical field
The present invention relates to a kind of technological process for coating, specifically, is a kind of technological process for coating that is applied to plastics-production equipment.
Background technology
Industrial manufacture composite film material or extrusion coating paper material, can adopt technological process for coating to be realized, traditional coating process is in operation process, must use the raw material of organic solvents such as containing acetone, chloroform, and to utilize the equipment such as bellows to dry it after coating, will give off harmful gas so in this course, this class gas equally also can contaminated air and welding.This is the technological deficiency that existing coating process exists.
Summary of the invention
The present invention discloses a kind of environmental protection and energy-conservation technological process for coating.
The present invention is achieved in that a kind of technological process for coating that is applied to the two machine drawings of plastics, comprises the steps.
Step 1: the two machine drawings of plastics start drawing plastic film.
Step 2: the two machine drawings of plastics are carried out horizontal drawing to film.
Step 3: when carrying out horizontal drawing, use aqueous solvent to be coated with operation to the film after horizontal drawing.
Step 4: the film after coating is carried out to the stable of drawing-off back pull, and the operation of shaping, also dries Coating simultaneously.
Described aqueous solvent is methyl alcohol and/or ethanol.
Temperature during described sizing operation is 200-250 degrees Celsius.
Temperature during described sizing operation is 230 degrees Celsius.
Use process of the present invention, due to film is horizontal draw after and before shaping film, use aqueous solvent to be coated with operation to film, can not discharge human body and the harmful gas of environment, high temperature while simultaneously utilizing sizing operation reaches the temperature of 200-250 degrees Celsius dries coating, through experiment, its drying effect is very good, dries coating and almost carries out with sizing operation simultaneously, simultaneously also save a large amount of electric energy, can reach environmental protection and energy-conservation beneficial effect.
The specific embodiment
The present invention is a kind of technological process for coating, is to be applied to a kind of technological process for coating on the two this membrane production equipments of machine drawing of plastic sheeting.Mainly on the activity bases of the two machine drawings of traditional plastic sheeting, added coating process, plastic sheeting is horizontal draw operation after, use aqueous solvent to be coated with operation to the horizontal operation film afterwards that draws, then carry out the stable of film drawing-off post-tensioning, carry out the sizing operation of film, operating temperature now reaches 200-250 degrees Celsius, in shaping film, the coating after coating is dried, its drying effect is good, coated and dried and shaping film are carried out simultaneously, both at operation process, can not discharge human body and the harmful gas of environment, also saved a large amount of electric energy, can reach environmental protection and energy-conservation technique effect.
