Problems solved by technology

In the current existing technology, stannous chloride is directly added in the form of powder during mixing. When adding materials, it is easy to have problems of inedible food and uneven dispersion; secondly, because the amount used in the formula is small, it is easy to stain It is on the wall of the equipment, so it is easy to measure inaccurately when weighing; in addition, it is easy to generate a lot of dust and volatiles when feeding, which will adversely affect the health of operators and the environment.
In order to solve the dispersion problem of stannous chloride in rubber and plastic products and improve its dispersion uniformity, the common practice is to increase the mixing temperature and prolong the mixing time, etc., but this will easily cause excessive crosslinking of rubber and plastic products, increasing the cost of production

preparation example Construction

[0018] The present invention also includes a preparation method of stannous chloride masterbatch, comprising the following steps,

[0019] (1) take various raw materials by weight ratio of tin protochloride masterbatch component;

[0020] (2) Place the raw materials in step (1) in the mixer and mix for 10-30min;

[0021] (3) Add the mixture obtained in step (2) to granulate in a twin-screw machine, and the screw speed is set to 200-1000r / min; after setting the temperature in each temperature zone, extrude and pelletize after passing through a 50-mesh filter screen to obtain Stannous chloride masterbatch.

[0022] Further, in the step (3), the temperature in the temperature zone is set to a temperature of 120-160°C in the first zone, a temperature in the second zone of 150-180°C, a temperature in the third zone of 140-170°C, a temperature in the fourth zone of 150-180°C, and a temperature in the fifth zone of 170°C. -190°C, the temperature in the sixth zone is 180-200°C, and ...

Embodiment approach 1

[0025] The preparation method steps are as follows:

[0026] (1) Take raw materials by the following parts by weight:

[0027]

[0028] (2) Place the raw materials of step (1) in a high-speed mixer and mix for 15 minutes;

[0029] (3) Put the mixture obtained in step (2) into a twin-screw machine for granulation, the screw speed is set to 200r / min, the temperature is 120°C in the first zone, 140°C in the second zone, 150°C in the third zone, and 150°C in the fourth zone. The temperature in the zone is 150°C, the temperature in the fifth zone is 170°C, the temperature in the sixth zone is 180°C, and the temperature in the seventh zone is 180°C. After passing through a 50-mesh filter, extrude and pelletize to obtain stannous chloride masterbatch. And the masterbatch is used to produce TPV (PP / EPDM dynamically vulcanized thermoplastic elastomer), that is, the weight ratio of TPV raw material and stannous chloride masterbatch is 100:1 to produce TPV, and the test results of TP...

Abstract

The invention relates to the technical field of high polymer materials, in particular to a stannous chloride master batch, which is prepared from the following components in parts by mass: 10 to 30 parts of SnCl2'2H2O, 60 to 80 parts of carrier resin, 1 to 5 parts of zinc oxide, and 1 to 5 parts of stearic acid. By adopting the method, the stannous chloride master batch prepared by the invention effectively reserves original activity of stannous chloride, has excellent heat resistance and ageing resistance, is non-caking at room temperature, and is easy to store and good in fluidity; environment protection is facilitated, convenience in feeding accurately is realized, the accuracy of a formula is ensured, a dispersion effect in an elastomer can be also improved, and the product quality isimproved and stabilized.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a stannous chloride masterbatch and a preparation method and application thereof. Background technique [0002] Stannous chloride (SnCl 2 2H 2 O) has the advantages of high purity, superior performance, and high added value. It is widely used in the rubber and plastic industry as an important additive, which can effectively improve the activity of vulcanizing agents and curing agents, shorten the vulcanization or curing reaction time, and improve production. efficiency. The uniformity of stannous chloride dispersion in rubber and plastics can directly affect the appearance and performance stability of products. In the current existing technology, stannous chloride is directly added in the form of powder during mixing. When adding materials, it is easy to have problems of inedible food and uneven dispersion; secondly, because the amount used in the formula is small, i...
