Description
[ technical field ] A method for producing a semiconductor device
The invention belongs to the technical field of polymers, and particularly relates to high-performance modified polyvinyl chloride.
[ background of the invention ]
Polyvinyl chloride is one of the earliest plastic varieties for realizing industrialization in the world, is a general resin with excellent performance and low price, has the advantages of excellent flame retardant property, corrosion resistance, wear resistance, small friction coefficient, low thermal conductivity, good sealing property, dust prevention, sound insulation, shock resistance, weather resistance and the like, and is widely applied to the fields of buildings, light industry, agriculture, packaging, daily use and the like. However, the polyvinyl chloride molecules contain a large amount of C-Cl bonds, and a large acting force exists among the molecules, so the polyvinyl chloride molecules are relatively hard, show a certain brittleness to the outside, and have poor impact strength.
Therefore, a high-performance modified polyvinyl chloride and a preparation method thereof are urgently needed.
[ summary of the invention ]
The invention provides high-performance modified polyvinyl chloride and a preparation method thereof, and the prepared product has a polyvinyl chloride material with excellent mechanical property by optimizing components and dosage.
In order to solve the technical problems, the invention adopts the following technical scheme:
the high-performance modified polyvinyl chloride is characterized by comprising the following raw materials in parts by mass: PVC, partially crosslinked nitrile rubber, a compound filler, modified calcium polyphosphate, a plasticizer, an antioxidant and a lubricant; the gel mass percentage content of the partially crosslinked nitrile rubber is 40-60%; the compound filler is formed by mixing hollow structure fibers and hydroxyl silicone oil, and the modified calcium polyphosphate is calcium polyphosphate subjected to surface modification by a silane coupling agent; the mass ratio of the PVC to the partially crosslinked nitrile rubber is 100: 15-25.
Further, the high-performance modified polyvinyl chloride comprises the following raw materials in parts by mass: 100 parts of PVC, 15-25 parts of partially crosslinked nitrile rubber, 5-10 parts of compound filler, 5-10 parts of modified calcium polyphosphate, 4-6 parts of plasticizer, 1-3 parts of antioxidant and 2-4 parts of lubricant.
Further, the compound filling agent is obtained by immersing the hollow structure fiber into hydroxyl silicone oil, ultrasonically vibrating for 5-15min, and filtering.
Further, the hollow structural fiber is nylon 66 chopped fiber with the hollowness of 10-20%.
Further, the plasticizer is DOP, DOS, DIDP, liquid polyester type.
Further, the compounding mass ratio of the calcium polyphosphate to the silane coupling agent in the modified calcium polyphosphate is 100: 5-10.
Further, the antioxidant is antioxidant 1010 or antioxidant DLTP.
Further, the lubricant is at least one of calcium stearate, paraffin wax and polyethylene wax.
The preparation method of the high-performance modified polyvinyl chloride is characterized by comprising the following steps:
(1) weighing PVC, partially crosslinked nitrile rubber, a compound filler, modified calcium polyphosphate, a plasticizer, an antioxidant and a lubricant according to the formula, and putting the materials into a mixer to be stirred for 1-3 minutes to obtain a mixed raw material;
(2) putting the mixed raw materials in the step 1 into a double-screw extruder for reaction, allowing the materials to stay in a machine barrel for 1-2min to obtain a reaction product,
(3) and cutting the reaction product into particles and drying to obtain a finished product.
Further, the temperatures of the zones of the twin-screw extruder are as follows: the first zone is 180-class at 200 ℃, the second zone is 200-class at 220 ℃, the third zone is 200-class at 220 ℃, the fourth zone is 200-class at 220 ℃, the fifth zone is 200-class at 220 ℃, the sixth zone is 200-class at 220 ℃, the seventh zone is 200-class at 220 ℃, the eighth zone is 200-class at 220 ℃, the ninth zone is 200-class at 220 ℃, and the head is 200-class at 210 ℃.
The invention has the following beneficial effects:
1) the invention takes PVC as a substrate, and adds the partially crosslinked nitrile rubber with certain gel content, thereby effectively improving the impact resistance of the polyvinyl chloride and balancing and improving other properties, wherein the impact resistance is reduced due to excessive gel content, and other mechanical properties are reduced due to excessive gel content.
2) The invention prepares the compound filling agent, and takes the modified calcium polyphosphate as the filling main body. The compound filler is a compound of hollow fibers and hydroxyl silicone oil, the impact resistance and other mechanical properties of the resin are greatly improved by adding the hollow fibers, and the hollowness of the hollow fibers is 10-20%. Too high hollowness will result in mechanical properties decreasing and easy to bubble, and too low hollowness will result in failure to achieve a large improvement in impact resistance. Through the pre-compounding of the hollow fiber and the hydroxyl silicone oil, the air reserved in the hollow fiber can be effectively removed, the bubbling phenomenon is prevented, and the dispersion can be promoted. Compared with other inorganic fillers, the modified calcium polyphosphate has the advantage that the overall rigidity of the polyvinyl chloride is greatly improved by adding the inorganic polymer with long chain. The compound filling agent and the modified calcium polyphosphate are added simultaneously, so that the polyvinyl chloride composite material has the characteristics of improving the mechanical properties of all polyvinyl chloride in a balanced manner and overcoming the characteristic that the traditional filling agent brings partial performance deterioration.
According to the high-performance modified polyvinyl chloride, the high-performance modified polyvinyl chloride is added with the partially crosslinked nitrile rubber, and the compound filler and the modified calcium polyphosphate are added, so that various mechanical properties of the polyvinyl chloride are further improved in a balanced manner.
