preparation example Construction

[0042] The preparation method of the disclosed ABS material comprises the following steps:

[0043] Step (1) Weighing raw materials in proportion.

[0044] Step (2) Put the first ABS resin, the second ABS resin, the AES resin and the dispersant into the mixer in sequence and stir evenly to obtain a premix. The sequential mixing of the first ABS resin, the second ABS resin, the AES resin and the dispersant is beneficial to ensure the mixing uniformity of each raw material. The stirring time in step (2) can be 2min-10min. Further, the stirring time in step (2) may be 5min-7min.

[0045] Step (3) adding the remaining raw materials into the obtained premixed material and stirring evenly to obtain the mixed material. After the preparation of the premix, the preparation of the mixture can effectively avoid the problem of uneven mixing of powdery raw materials and other types of original materials, thereby ensuring the uniform mixing of each raw material, which is conducive to obt...

Abstract

The invention discloses an ABS material and a preparation method thereof. The ABS material is prepared from, by weight, 70-85 parts of first ABS resin, 5-15 parts of second ABS resin, 10-20 parts of AES resin, 0.2-0.6 part of hindered phenol antioxidant, 0.2-0.6 part of phosphite antioxidant, 0.1-1.0 part of ultraviolet light absorber, 0.1-0.8 part of hindered amine light stabilizer, 0.2-0.5 partof lubricating agent and 0.3-0.6 part of dispersing agent; the first ABS resin is synthesized ABS resin by using a continuous bulk method, and the second ABS resin is the synthesized ABS resin by using a emulsion polymerization method. By utilizing synergistic effects among all the components, the method improves the weather-proof performance and mechanical performance of the ABS material.

Description
