Color powder, the degree of branching is smaller, poor to the stability of light and heat.Different additives, polychlorostyrene can be added according to different purposes
Different physical property and mechanical property can be presented in vinyl plastics.Suitable plasticizer is added in Corvic, can make
At a variety of hard, soft and transparent article.
PVC was most had found early in 1835 by the famous scientist (Henri Victor Regnault) of France.Then exist
German another one scientist (Eugen Baumann) has also discovered this new material within 1872.It is white in PVC material at that time
The solid of color, great fragility, there is no actual applications.In Russia chemist (Ivan early 20th century
Ostromislensky) and the chemical personage of a batch such as Fritz Klatte once attempts to change the fragility of pvc, becomes
Commercial product still has failed and comes to an end.
Currently, PVC material in our life using very universal, but many PVC material quality are softer, hardness
It is not high, usually scratch can be scraped by sharp thing during use.

C, it adds reagent: will successively add various reagents in raw material that melted PVC material produces；
D, it produces: the raw material prepared is used for the preparation of PVC material；
E, the PVC finished-product material of preparation is handled.
Preferably, the raw material melamine for preparing PVC production according to step A, hard vinyl chloride resin, nanometer two
Titanium dioxide powder, nano silica, nanometer titanium dioxide iron, epoxy resin, antioxidant, compound stabilizer, levelling agent, ring
Oxygen reinforcing agent, defoaming agent, fire retardant, plasticizer, toughener.
Preferably, described according to step B
A, first by melamine, epoxy resin is weaved with Corvic and is blended in pulverizer；
B, the melamine that will be blended, epoxy resin and hard vinyl chloride resin are placed in thawing vat, and being heated to 150 DEG C makes three
Poly cyanamid, epoxy resin and hard vinyl chloride resin are melted in 5min at 150 DEG C, using blender to the melamine of thawing,
Epoxy resin is stirred with hard vinyl chloride resin, mixing speed 60r/min.
Preferably, described according to step C
A, by nano titanium dioxide powder, nano silica, nanometer titanium dioxide iron, antioxidant, compound stabilizer, epoxy
Reinforcing agent, fire retardant, plasticizer, toughener are added, and stir 8-10min；
B, 5min is stirred after being subsequently added into defoaming agent, is then allowed to stand 8min, temperature is dropped to 120 DEG C.
Preferably, the PVC that will be prepared according to step D prepares the equipment or mould that raw material pours into PVC material preparation
In tool, and increase levelling agent on the surface of the material, is solidified using water-cooled cooling.
Preferably, described to be carried out the edge for preparing molding PVC material according to step E to cut finishing.
Compared with prior art, the beneficial effects of the present invention are:
The present invention uses perfect preparation process, and the PVC material produced not only has good toughness, while hardness is high, has
The advantages of scratch resistance.
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 processing technology of hard PVC material, the following steps are included:
A, prepare: get out hard PVC material prepares raw material；
B, melt: the PVC production basic material of preparation is melted according to preparation flow；
C, it adds reagent: will successively add various reagents in raw material that melted PVC material produces；
D, it produces: the raw material prepared is used for the preparation of PVC material；
E, the PVC finished-product material of preparation is handled.
A prepares the raw material melamine of PVC production, hard vinyl chloride resin, nano titanium dioxide powder, nano-silica
SiClx, nanometer titanium dioxide iron, epoxy resin, antioxidant, compound stabilizer, levelling agent, epoxy reinforcing agent, defoaming agent are fire-retardant
Agent, plasticizer, toughener.
20 parts of melamine, 50 parts of hard vinyl chloride resin, 15 parts of nano titanium dioxide powder, nano silica 12
Part, 5 parts of nanometer titanium dioxide iron, 35 parts of epoxy resin, 4 parts of antioxidant, 3 parts of compound stabilizer, 10 parts of levelling agent, epoxy increases
Gu 15 parts of agent, 5 parts of defoaming agent, 8 parts of fire retardant, 4 parts of plasticizer, 6 parts of toughener.
