Swelling development device and preparation process for high-fracture-resistant SBS composite material

Abstract

The invention discloses a swelling development device for a high-fracture-resistant SBS composite material. The swelling development device comprises an H-shaped bracket, wherein a swelling chamber and a development chamber are fixedly mounted at the top of the H-shaped bracket; the swelling chamber comprises a pressure reaction kettle, an electric heating block is mounted in the pressure reactionkettle, and a top cover is arranged above the pressure reaction kettle; the development chamber comprises a screw extruder, a high-speed stirring tank is mounted at an output end of the screw extruder, a stirring shaft is mounted in the high-speed stirring tank, and stirring auxiliary blades are mounted on the stirring shaft, and provided with shearing grinding knives; a development tank is arranged below the high-speed stirring tank, a plurality of bubble spray heads are mounted at the bottom of the development tank, and intensive heating plates are mounted in the development tank; and an air pump conveying device communicated with the screw extruder is fixedly mounted at the bottom of the development tank. The invention further discloses a preparation process. Based on the preparation process, a net-shaped or an island-shaped structure is formed in the composite material, so that the composite material has relatively strong fracture resistance, the streamlined and crossed productionis realized, and the efficiency of the integral device is improved.

Description

technical field [0001] The invention relates to the technical field of composite material preparation, in particular to a swelling development device for high flexural-resistant SBS composite materials and a preparation process thereof. Background technique [0002] Polystyrene-polybutadiene-polystyrene block copolymer (SBS) has the advantages of good chemical stability, low price and convenient processing. It is one of the important general-purpose plastics in industrial applications, but its impact strength is not High, easy to deform, and in practical applications, the application and transportation will be restricted due to its poor bending resistance. Based on the above defects, the wide application of SBS is severely limited. [0003] In order to expand the application field of SBS, inorganic rigid particles are generally used to toughen SBS to improve the strength and toughness of the material. However, due to the large difference in surface energy between inorganic r...

Problems solved by technology

[0005] (1) In the existing formula, there is often a lack of promoting substances, so that the SBS and other ingredients cannot be completely integrated with each other. Therefore, to achieve the design effect, a large amount of expensive SBS must be used, which is very important for SBS composite materials. For a large number of applications, the cost is relatively high;

[0006] (2) In the existing process, the process control is complicated, and the parameters of the production process need to be quantified and then controlled one by one, and the production process cannot meet the performance required in the design for SBS composite materials;

[0007] (3) In combination with the technology in the prior art and related preparation devices, there is a lack of one-stop assembly line production technology, and what is often used is that each process is separated from each other, and then produced according to the established process flow, which will lead to the following There are two problems: first, the process will be more complicated, requiring high-intensity manual intervention, and it is not possible to add and mix ingredients in a timely manner; second, for the coordinated processing between processes, it cannot realize the process The cross-coordination between them often requires the cooperation of other related equipment to complete the relevant production process.
