Embodiment 1

[0017] Embodiment 1: 70 parts of calcium terephthalate and 5 parts of paraffin are stirred at 1000 rev / min for 3 min in a stirred tank, then jump to high-speed stirring at 5000 rev / min for 4 min, change to 2000 rev / min Slowly add 5 parts of silane coupling agent Si69, stir for 5 min, then add 25 parts of carrier resin EVA, stir and mix at 150° C. for 15 min. Finally, the processed material is extruded at 100° C., hot-cut and air-cooled to obtain the masterbatch product obtained by the present invention.

Embodiment 2

[0018] Embodiment 2: 30 parts of magnesium terephthalate and 10 parts of white oil were stirred at 500 rev / min for 5min in a stirring tank, then jumped to high-speed stirring for 8min at 4000 rev / min, and changed under 1500 rev / min Slowly add 10 parts of silane coupling agent Si75 at a medium speed, stir for 5 minutes, then add 60 parts of carrier resin PE, and stir at 100° C. for hot melt mixing and stirring for 5 minutes. Finally, the processed material is extruded at 90°C, hot-cut, and air-cooled to obtain the master batch product of the present invention.

Embodiment 3

[0019] Embodiment 3: 85 parts of zinc terephthalate and 5 parts of stearic acid are stirred at 800 rev / min for 4min in the stirring tank, then jump to high-speed stirring 6min at 4500 rev / min, change 1200 rev / min Slowly add 5 parts of silane coupling agent Si230 at a medium speed, stir for 4 minutes, then add 5 parts of carrier resin PP, and stir at 70° C. for hot melt mixing and stirring for 10 minutes. Finally, the processed material is extruded at 100° C., hot-cut and air-cooled to obtain the masterbatch product obtained by the present invention.

Abstract

The invention relates to a plastic filling master batch, which contains carrier resin, terephthalic acid metal salt, silane coupling agent and lubricating agent. The carrier resin is selected from new plastic or reprocessed plastic; the terephthalic acid metal salt is selected from one or more of sodium terephthalate, magnesium terephthalate, zinc terephthalate, potassium terephthalate, sodium terephthalate, barium terephthalate, lead terephthalate, aluminum terephthalate and ferric terephthalate; the silane coupling agent is selected from one or more of bis(gamma-triethoxysilylpropyl) tetrasulfide, bis-(triethoxysilylpropyl) disulfide and gamma-chloropropyl triethoxysilane; and the lubricating agent is selected from one or more of paraffin, white oil and stearic acid. The invention also relates to a preparation method for the filling master batch. Through the filling master batch provided by the invention, a plastic product has good surface glossiness and is not easily aged, and the tensile strength and the impact strength of the product are improved.

Description

technical field [0001] The invention relates to a plastic filling master batch and a preparation method thereof. Background technique [0002] With the rapid development of the plastics industry, plastic products have been widely used. Plastic modification has also become a popular subject at home and abroad. Adding filler materials to plastics is a very common method of plastic modification. By adding some additives, it can not only reduce the production cost of plastic products, improve the utilization rate of resins, but also expand the application scope of resins. [0003] The traditional method of plastic modification is to directly mix filler materials and auxiliaries and then add them to the matrix resin for molding, but this method is difficult to mix the fillers, auxiliaries and resins uniformly. Plastic filled modified masterbatch is produced after the improvement of the traditional method of plastic modification. It can ensure good processing performance while a...
