preparation example Construction

[0037] The present invention also provides a method for preparing a large-phase region size transparent ABS resin composition, the method can adopt bulk polymerization method or solution polymerization method, specifically comprising:

[0038] Step 1: dissolving styrene-butadiene block copolymer or random copolymer in diluent, styrene monomer, (meth)acrylate monomer and vinyl nitrile monomer to prepare raw materials solution mixture;

[0039] Step 2: Add the raw material solution mixture obtained in Step 1 into the reactor, add an initiator and a molecular weight regulator, and carry out a polymerization reaction. The polymerization temperature is preferably 120-140°C, and the polymerization time is preferably 1-8 hours. After completion, the large-phase region size transparent ABS resin composition is obtained through devolatilization.

[0040] According to the present invention, the diluent includes aromatic hydrocarbons, aliphatic hydrocarbons, ketone hydrocarbons, ester c...

Embodiment 1

[0056] Weigh 10 parts of styrene-butadiene block copolymer (the weight of styrene skeleton accounts for 24% of the total weight of styrene-butadiene copolymer) and dissolve in 41 parts of xylene, 25.5 parts of styrene, 59.5 parts of methyl Methyl acrylate and 5 parts of acrylonitrile to obtain a mixture. After completely dissolving, the mixture was added to the reaction kettle, and at the same time, 500 ppm of di-tert-butyl peroxide was added. Under the condition of nitrogen protection, the polymerization reaction was carried out. The reaction temperature was 130 ° C. The reaction time was 150 minutes. After the reaction, the volatile components were removed to obtain a transparent rubber-modified styrene resin composition, and the monomer conversion rate was 61%.

[0057] The obtained transparent rubber-modified styrene-based resin composition was molded into sheets of 120×65×3.5mm and 100×65×1mm on a flat vulcanizing machine at 180°C, and cut into impact splines and tensile s...

Abstract

The invention provides a transparent ABS resin composition with large phase zone dimension and a preparation method thereof, and belongs to the technical field of high-molecular material. The transparent ABS resin composition includes, by weight, 6-12% of dispersed rubbery copolymer particles and 88-94% of a copolymer continuous phase with number-average molecular weight of 40000-150000 and weight-average molecular weight of 50000-300000. The invention also provides the preparation method of the transparent ABS resin composition with large phase zone dimension. The composition can well control the dimension of rubber particle as the dispersed phase by adjusting the molecular weight of the copolymer continuous phase. Almost all rubber particles as dispersed phase have inner containment structure, and the rubber particle size is 0.3 to 1.2 mum. The transparent ABS resin composition with large phase zone dimension has good transparency and excellent anti impact properties.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a transparent ABS resin with a large phase region size and a preparation method thereof. Background technique [0002] In recent years, with the development of society, the demand for transparent resin is increasing. As a new type of polymer transparent material, transparent ABS resin has good mechanical properties and reasonable Therefore, transparent ABS resin has been greatly developed. [0003] At this stage, the demand gap in the domestic market for transparent ABS resin is getting bigger and bigger, and almost all finished products of transparent ABS resin rely on foreign imports. However, how to balance the optical and mechanical properties of transparent ABS resins has become a technical problem. The impact resistance of transparent ABS resins sold in the market today is generally low. The reason is that the size of the rubber particles used as the ...
