Embodiment Construction

[0017] Such as figure 1 As shown, the high-impact polystyrene cup includes a cup body 1, the outer side of the cup body 1 is a low-temperature resistant layer 2, the inner side of the cup body 1 is a crack-resistant layer 3, and the low-temperature resistant layer 2 and the anti-crack layer The cracked layer 3 is composited into the cup wall 11 of the cup body 1 and the cup bottom 12 of the cup body 1, and the ratio of the thickness of the low temperature resistant layer 2 to the thickness of the crack resistant layer 3 is 1:10, and the cup wall 11 A cavity 13 is formed along the side wall of the cup bottom 12, the low temperature resistant layer 2 is GPPS, the crack resistant layer 3 is HIPS and SBS, and the mass ratio of HIPS to SBS is 8:1 , the thickness of the low-temperature-resistant layer 2 is 0.05mm, which has good low-temperature resistance and good practicability. The thickness of the crack-resistant layer 3 is 0.5mm, which ensures that the cup body 1 will not break ...

Abstract

The invention relates to a high impact polystyrene cup which comprises a cup body. A low-temperature-resistant layer is arranged on the outer side of the cup body. An anti-cracking layer is arranged on the inner side of the cup body. The low-temperature-resistant layer and the anti-cracking layer form the cup wall and the cup bottom of the cup body in a composite mode. The percentage of the thickness of the low-temperature-resistant layer and the thickness of the anti-cracking layer is 1:20-1:10. The cup wall forms a placing cavity in a surrounding mode along the side wall of the cup bottom. The low-temperature-resistant layer is made of GPPS. The anti-cracking layer is made of HIPS and SBS. The percentage of the mass of the HIPS and the mass of the SBS is 9:1-8:1. The high impact polystyrene cup has the advantages that the anti-cracking layer is made of the HIPS and the SBS by reasonable matching, the low-temperature-resistant layer is arranged on the outer side of the anti-cracking layer in a composite mode, so that the fact that the cup body has low-temperature-resistant performance is guaranteed, the cup body has anti-impact performance, the fact that the cup body is not broken under impact of external force is guaranteed, breaking rate is lowered, and service life is prolonged.

Description

technical field [0001] The present invention relates to high impact polystyrene cups. Background technique [0002] At present, the cups used for low-temperature products such as ice cream are made of polystyrene, and polystyrene products have good low-temperature resistance, but their impact resistance is poor, and they are easy to crack when deformed by external forces, which affects their use, storage, and quality. Transportation and handling increase the production cost, reduce the service life of the cup body, and result in poor use effect. Contents of the invention [0003] The technical problem to be solved by the present invention is that the existing cup body is easy to break when it is squeezed by external force, the impact resistance is poor, and the use effect is poor, resulting in high production cost and short service life of the cup body, so as to provide high impact poly Styrene cups. [0004] In order to solve the above technical problems, the present in...
