Embodiment 1

[0032] Add 100 parts of SBS, 2 parts of light calcium carbonate and 6 parts of paraffin base oil into the mixer, then stir at 160°C at a speed of 60r / min for 10 minutes, then at a temperature of 150°C, adjust the speed to 50r / min min, put 0.5 part of p-phenylenediamine and 0.5 part of 2,8-di-tert-butyl-4-methylphenol and 1 part of 2,5-dimethyl-2,5-bis(tert-peroxide Butyl)hexane was stirred for 5 minutes, then at a temperature of 160°C, the speed was adjusted to 40r / min, and 0.5 parts of 2,2,6,6-tetramethylpiperidone and 0.5 parts of stearic acid were put into the mixer and 4 parts of paraffin base oil and then stirred for 8 minutes, and then the uniformly mixed rubber material was put into a twin-screw extruder for extrusion, and pelletized by a pelletizer to obtain pellets for coating film. The above components are all measured by mass fraction.

Embodiment 2

[0034] Add 100 parts of SBS, 4 parts of light calcium carbonate and 7 parts of paraffin base oil into the mixer, then stir at 175°C at a speed of 65r / min for 15 minutes, then at a temperature of 160°C, adjust the speed to 55r / min min, put 0.75 parts of p-phenylenediamine and 0.75 parts of 2,8-di-tert-butyl-4-methylphenol and 1.5 parts of 2,5-dimethyl-2,5-bis(tert-peroxide Butyl)hexane was stirred for 7 minutes, then at a temperature of 175°C, the speed was adjusted to 45r / min, and 1 part of 2,2,6,6-tetramethylpiperidone and 1 part of stearic acid were put into the mixer and 3 parts of paraffin base oil and then stirred for another 7 minutes, and then the uniformly mixed rubber material was put into a twin-screw extruder for extrusion, and pelletized by a pelletizer to obtain pellets for coating film. The above components are all measured by mass fraction.

Embodiment 3

[0036]Add 100 parts of SBS, 5 parts of light calcium carbonate and 10 parts of paraffin base oil into the mixer, then stir at 190°C at a speed of 65r / min for 15 minutes, then at a temperature of 170°C, adjust the speed to 55r / min min, put 0.75 parts of p-phenylenediamine and 1 part of 2,8-di-tert-butyl-4-methylphenol and 1.75 parts of 2,5-dimethyl-2,5-bis(tert-peroxide Butyl)hexane was stirred for 7 minutes, then at a temperature of 180°C, the speed was adjusted to 45r / min, and 2 parts of 2,2,6,6-tetramethylpiperidone and 0.5 parts of stearic acid were put into the mixer and 5 parts of paraffin base oil and then stirred for another 7 minutes, and then the uniformly mixed rubber material was put into a twin-screw extruder for extrusion, and pelletized by a pelletizer to obtain pellets for coating film.

Abstract

The invention relates to a pelleting method of aggregates used for an encapsulating film, aggregates thereof and application. On one hand, the pelleting method comprises the following steps: adding main body resin, an inorganic filler and a part of a softener into a mixing machine for stirring and mixing, then after warming to adjust the rotating speed, putting into an antioxygen and a cross-linking agent, finally putting into a stabilizer and the rest of the softener, and then carrying out extrusion pelletization on a double-screw extruder so as to obtain the aggregates used for the encapsulating film. On the other hand, the encapsulating film is obtained through curtain coating and cooling of the prepared and obtained aggregates used for the encapsulating film, and the encapsulating film has excellent mechanical property, weather resistance and water resistance and can be used for surface encapsulating of automobile foaming body materials.

Description

technical field [0001] The invention relates to a granulation method of resin granules, the granules and applications thereof, in particular to a granulation method of the granules for coating films, the granules and applications thereof. Background technique [0002] At present, the coating film materials used for automobile foam materials mainly include thermoplastic elastic paint materials such as SBS, POE, TPVC, and TCPE. Thermoplastic elastic has a wide range of hardness, high strength, and has excellent weather resistance, oil resistance and processability. However, due to the fact that thermoplastic elastomers are easy to hydrolyze, easy to decompose at high temperatures, and high in price, if they are not modified, they will be used in automobiles. There are often many problems in the practical application of foam materials. [0003] US200408116A1 discloses an oriented thermoplastic elastomer film and its preparation method. The film includes a dynamically vulcanize...
