Technical field
The invention belongs to technical field of polymer, and in particular to one kind is resistance to decompose weather-proof coloring polyvinyl chloride and its preparation side
Method.
Background technology
The main component of plastics is synthetic resin.This noun of resin is initially the lipid secreted out of by animals and plants and obtains
Name, such as rosin, shellac, resin refers to the high polymer not yet mixed with various additives at present, and polyvinyl chloride is polyamide resin
Fat, most one of several engineering plastics of application at present, his amide group have polarity, have structure jail in his structure
Solid hydrogen bond so that the fusing point of polyvinyl chloride is higher, has good physical and mechanical property and wearability and self lubricity, this
A little Comprehensive Characteristics are not available for other plastics.But the impact strength of pure polyvinyl chloride is relatively low, when compared with low ambient temperature
This disadvantage is more prominent.Therefore, the research that compound impact modification is carried out to polyvinyl chloride is expanded.Cold-resistant toughened polychlorostyrene second
Alkene is because of the intrinsic characteristic of holding resin, and impact strength improves ten and arrives decades of times, can still possess under extremely low temperature good
Toughness, it might even be possible to reach fall it is not rotten pound not broken degree, can application range constantly be expanded.It is jagged manufacturing
Or the product of acute angle, or be required to tolerance extremely low temperature and still keep excellent toughness and alternative metals to mitigate weight again
, there is irreplaceable advantage in the field for improving performance and service life.
Although currently, the plastics that some occurred in the market are made by polyvinyl chloride have at a certain temperature it is cold-resistant and
Tough and tensile feature, but it is perfect not enough in degree, and such as the temperature of low spot, many plastics can all have phenomenon easy to crack again.Separately
Outside, some are very high by the Related product price of the external major company of nylon 6, and the presence of the product of domestic manufacturer sacrifices nylon 6
The a certain advantage of itself, or cause product with stable quality control bad since technique or technology are not enough, it is unable to scale
It produces and uses, this technology invention is exactly to be generated to effectively overcome above-mentioned technological deficiency.
Therefore, urgent need is a kind of has excellent resistance to decomposition weather-proof and the coloring PVC resin composition of physical property.
Invention content
The present invention provides resistance to weather-proof coloring polyvinyl chloride of decomposition of one kind and preparation method thereof, passes through and optimizes component, dosage, system
The product obtained has excellent resistance to decomposition weather-proof and physical property.
In order to solve the above technical problems, the present invention uses following technical scheme：
A kind of resistance to weather-proof coloring polyvinyl chloride of decomposition, which is characterized in that as unit of mass parts, including the following raw material：PVC, chlorine
Buna, polysulfide rubber, compound coloring agent, dimethyl silicone polymer, plasticizer, antioxidant, lubricant；The compound coloring agent
It is 100 including mass ratio：（40-60）：（20-40）：（40-60）Sodium Polyacrylate, white carbon, titanium dioxide, inorganic pigment, institute
PVC is stated, the mass ratio of neoprene, polysulfide rubber is 100:5-10:5-10, the additive amount of the compound coloring agent relative to
The 10-20 mass % of PVC.
Further, the weather-proof coloring polyvinyl chloride of the resistance to decomposition, as unit of mass parts, including the following raw material：
PVC100 parts, 5-10 parts of neoprene, 5-10 parts of polysulfide rubber, 10-20 parts of compound coloring agent, dimethyl silicone polymer 5-10
Part, 2-4 parts of plasticizer, 1-3 parts of antioxidant, 2-6 parts of lubricant.
Further, the mass ratio of the PVC, neoprene, polysulfide rubber are 100:7.5: 7.5.
Further, it is 100 that the compound coloring agent, which includes mass ratio,：50：30：50 Sodium Polyacrylate, white carbon, titanium
White powder, inorganic pigment.
Further, the plasticizer DOP, DOS, DIDP, liquid polyester type.
Further, the molecular weight of the Sodium Polyacrylate is 4000-10000.
Further, the antioxidant is antioxidant 1010 or anti-oxidant DLTP.
Further, the lubricant is at least one of calcium stearate, paraffin, polyethylene wax.
A kind of preparation method according to the above-mentioned weather-proof coloring polyvinyl chloride of resistance to decomposition, which is characterized in that including following step
Suddenly：
（1）Sodium Polyacrylate, white carbon, titanium dioxide, inorganic pigment are kneaded in high speed mixing smelting machine in proportion 5-10 minutes and are made
Obtain compound coloring agent；
（2）PVC, neoprene, polysulfide rubber, compound coloring agent, dimethyl silicone polymer, plasticising are weighed according to a formula
Agent, antioxidant, lubricant are put into mixer and are stirred 1-3 minutes, obtain mixed raw material；
（3）The mixing product of the mixed raw material of step 2 and step 1 is put into double screw extruder and is reacted, material exists
Residence time 1-2min in machine barrel, obtains reaction product,
（4）Finished product will be obtained after reaction product pelletizing, drying.
Further, each area's temperature of the double screw extruder is as follows：One 180-200 DEG C of area, two 200-220 DEG C of areas,
Three 200-220 DEG C of areas, four 200-220 DEG C of areas, five 200-220 DEG C of areas, six 200-220 DEG C of areas, seven 200-220 DEG C of areas, 8th area
200-220 DEG C, nine 200-220 DEG C of areas, 200-210 DEG C of head.
The invention has the advantages that：
1) present invention is using PVC as matrix, and by the way that neoprene is added, polysulfide rubber, dimethyl silicone polymer is as synergistic
Component effectively enhances the effect of resistance to decomposition of the coloring PVC under ultraviolet light irradiation, decomposes to play to pigment and centainly cover
Effect, while the mechanical property of PVC is also enhanced to a certain extent.
2）The present invention is prepared for compound coloring agent, including certain mass than Sodium Polyacrylate, white carbon, titanium dioxide, nothing
