Preferably, it is described according to step D by stabilizer, lubricant, antioxidant, epoxy reinforcing agent, toughener is added to PVC
Mixing is heated in raw material, maintains 120 DEG C of standing 10-15min after mixing evenly.
Preferably, described according to step E
A, one layer of release agent will be smeared in the equipment for producing PVC material；
B, ready raw material are injected into the production equipment of PVC material；
C, after being down to 70-80 DEG C to PVC material temperature, by one layer of levelling agent on the surface of PVC material；
D, it is taken out after PVC material is cooling, and the PVC material of production is modified.
Compared with prior art, the beneficial effects of the present invention are:
PVC material produced by the invention is clear, colorless material, and cleannes are high, is had the characteristics that environmental and durable.
Specific embodiment
The following is a clear and complete description of the technical scheme in the embodiments of the invention, it is clear that described embodiment
Only a part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, the common skill in this field
Art personnel every other embodiment obtained without making creative work belongs to the model that the present invention protects
It encloses.
The invention provides the following technical scheme: a kind of preparation process of soft transparent PVC material, the following steps are included:
A, prepare: preparing the raw material and additive of PVC material production；
B, it cleans: being cleaned after PVC raw material are proportionally mixed；
C, melt: by the raw material mixed heating and melting after mixing；
D, additive is added: additive is added into the raw material after thawing；
E, it produces: the raw material injection production equipment of preparation is subjected to production.
The raw material of the PVC material include epoxy resin, waterborne polyurethane resin, kaolin, polyvinyl chloride, lightweight activity
