preparation example 1

[0044] According to the actual amount of talcum powder used, weigh a certain amount of talcum powder, and weigh a certain amount of tannic acid according to the weight ratio of talcum powder and tannic acid being 1:0.1. According to the weight ratio of tannic acid to water of 1:10, the weighed tannic acid was mixed with water, stirred and dissolved to obtain an aqueous solution of tannic acid. Mix the talcum powder with the tannic acid aqueous solution, then filter, and dry the collected talcum powder at 60° C. for 30 minutes to obtain the modified talcum powder, which is set aside. Among them, tannic acid is condensed tannic acid.

[0045] By adopting the above method, modified barium sulfate, modified calcium carbonate, modified mica and modified wollastonite were respectively prepared.

preparation example 2

[0047] According to the actual amount of talcum powder used, a certain amount of talcum powder was weighed, and a certain amount of tannic acid was weighed according to the weight ratio of talc powder and tannic acid being 1:0.15. According to the weight ratio of tannic acid to water of 1:15, the weighed tannic acid was mixed with water, stirred and dissolved to obtain an aqueous solution of tannic acid. Mix the talcum powder with the tannic acid aqueous solution, then filter, and dry the collected talcum powder at 70° C. for 30 minutes to obtain the modified talcum powder, which is set aside.

preparation example 3

[0049] According to the actual amount of talcum powder used, a certain amount of talcum powder was weighed, and a certain amount of tannic acid was weighed according to the weight ratio of talc powder and tannic acid being 1:0.13. According to the weight ratio of tannic acid to water of 1:13, the weighed tannic acid was mixed with water, stirred and dissolved to obtain an aqueous solution of tannic acid. Mix talcum powder and tannic acid aqueous solution, then filter, and dry the collected talcum powder at 80° C. for 30 minutes to obtain modified talcum powder, which is set aside.

Abstract

The invention relates to the field of filling master batches, and particularly discloses a high-filling master batch for nylon and a preparation method of the high-filling master batch. The high-filling master batch for nylon is prepared from the following raw materials in parts by weight: 45-80 parts of inorganic mineral filler, 1-2 parts of a lubricant, 20-55 parts of nylon resin, 0.3-0.5 part of an antioxidant and 0.3-0.5 part of an auxiliary antioxidant, the preparation method comprises the following steps: S1, weighing the inorganic mineral filler, the lubricant, the nylon resin, the antioxidant and the auxiliary antioxidant in proportion; and S2, uniformly mixing the raw materials weighed in the step S1, extruding braces by using a screw extruder, cooling and pelletizing to obtain the high-filling master batch for nylon. The high-filling master batch for nylon has the advantages of being free of spots and free of dust in the using and processing process; in addition, the preparation method disclosed by the invention has the advantage of promoting the inorganic mineral filler to be uniformly dispersed in the filling master batch.

Description

technical field [0001] The application relates to the field of filler masterbatches, more specifically, it relates to a high-filler masterbatch for nylon and a preparation method thereof. Background technique [0002] Nylon resin has good comprehensive properties, including mechanical properties, heat resistance, wear resistance and chemical resistance, and is easy to process. It is widely used to make parts of various machinery, automobiles, chemicals, electronics and electrical devices. part. [0003] The application of filler masterbatch in plastics can reduce the raw material cost of plastic products, save synthetic resin, and also have the characteristics of improving the physical properties of plastic products and improving processing efficiency. The filler masterbatch for nylon is a concentrate made by adding a super-normal amount of plastic additives to the resin. In the subsequent manufacture of plastic products, it is not necessary to add this kind of plastic addi...
