Example Embodiment

[0015] The present invention will be further described below in conjunction with specific embodiments.

[0016] According to the weight shown in Table 1, the raw gum solution is proportioned to each component.

[0017] Table 1 The weight of each component of Examples 1-5

[0018]

[0019] Remarks: Star-shaped low cis rubber and styrene butadiene rubber compound ratios are 1:1, 1:2, 1:3, 2:1 and 3:1 respectively. The star-shaped low cis rubber is preferably Lanxess 565T, and the styrene-butadiene rubber is made by itself. The fourth monomer is preferably butyl acrylate.

[0020] Among them, the preparation process is as follows:

[0021] 1. Add rubber, ethylbenzene, styrene, acrylonitrile and the fourth monomer into the liquid mixing tank according to the glue formula, and dissolve them in the liquid mixing tank to a uniform raw glue liquid;

[0022] 2. The raw glue liquid is transported to four parallel plug flow tubular reactors connected in series by the feed pump;

[0023] 3. Add init...

Abstract

The invention belongs to the field of polymer materials, and in particular, relates to a preparation method of high-gloss bulk ABS resin. The high-gloss ABS resin is prepared by using a bulk ABS device, star-shaped low-cis rubber and butadiene styrene rubber are compounded to form rubber, the proportion of an original rubber solution and the addition amount of a chain transfer agent are adjusted,a fourth monomer is added to prepare the high-gloss bulk ABS resin, and the glossiness of the product reaches 85 or above. The preparation method disclosed by the invention is simple in process, low in production cost and good in product stability, and can meet the requirement of daily supplies such as household appliances, electronic appliances and automobiles on high glossiness of a resin material.

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to a preparation method of high-gloss bulk ABS resin. Background technique [0002] ABS resin is one of the five general-purpose synthetic resins, and its application fields have been extended to all aspects of industry and daily life. With the rapid development of my country's economy and the continuous improvement of people's living standards, the performance requirements of ABS resins are continuously improved. At present, most domestic ABS manufacturers can only produce general-purpose products. The continuous bulk method is used to produce ABS resins because of its simple process flow and The advantages of no wastewater discharge, green environmental protection, and excellent product performance will become the development direction of the ABS resin industry in the future. [0003] Patent CN101058623A discloses the preparation of high-gloss ABS resin by the continuo...
