Preparation method of easy-to-dry porous ABS grafted polymer particles

Abstract

The invention discloses a preparation method of an easy-to-dry porous ABS grafted polymer particle, belongs to the technical field of ABS grafted polymer preparation, and particularly relates to a preparation method of an easy-to-dry porous ABS grafted polymer particle. A particle hanging carrier curtain is used as a carrier for aggregation of ABS fine particles, so that the ABS fine particles are attached to the particle hanging carrier curtain to be formed; then stripping treatment is carried out on the ABS fine particles on the hanging particle carrier curtain, so that the ABS fine particles are separated from the hanging particle carrier curtain, and meanwhile, holes form in the ABS fine particles after the hanging particle carrier curtain leaves, so as to obtain the perforated ABS grafted polymer particles. Compared with the complete ABS particles prepared by the prior art, the internal and external surface areas of the ABS grafted polymer particles can be greatly increased, the transfer path of heat in the particles in the drying process is effectively reduced, that is, the transfer time of the heat to the interiors of the particles is reduced, the drying efficiency of the ABS grafted polymer particles is improved; meanwhile, the condition of nonuniform drying inside and outside the particles is reduced.

Description

technical field [0001] The invention relates to the technical field of preparing ABS grafted polymers, in particular to a method for preparing easy-drying ABS grafted polymer particles with holes. Background technique [0002] ABS plastic is a terpolymer of acrylonitrile (A)-butadiene (B)-styrene (S). It combines the properties of three components, among which acrylonitrile has high hardness and strength, heat resistance and corrosion resistance; butadiene has impact resistance and toughness; styrene has high surface gloss, easy coloring and Ease of processing. The characteristics of the above three components make ABS plastic a thermoplastic with good comprehensive properties of "hard quality, toughness, and high rigidity". Adjust the ratio of the three components of ABS, and its performance will also change to meet the requirements of various applications, such as high-resistant ABS, heat-resistant ABS, high-gloss ABS, etc. [0003] There are many industrial production ...

Problems solved by technology

[0011] Aiming at the problems existing in the prior art, the purpose of the present invention is to provide a kind of preparation method of easy-drying type ABS grafted polymer particles with holes, which makes the ABS The fine particles are attached to it to form, and then the ABS fine particles on the hanging particle carrier curtain are stripped, so that the ABS fine particles are separated from the hanging particle carrier curtain, and at the same time, the hanging particle carrier curtain leaves holes on the ABS fine particles , so as to obtain the porous type ABS grafted polymer particles, compared with the complete ABS particles prepared by the prior art, the present invention can greatly increase the internal and external areas of the ABS grafted polymer particles, effectively reducing the heat in the particle during the drying process. The internal transfer distance, which reduces the transfer time for heat to reach the inside of the particle, not only improves the drying efficiency of the ABS grafted polymer particle, but also reduces the uneven drying inside and outside the particle
