Problems solved by technology

HIPS is cheap and has good impact resistance, but it also has very obvious shortcomings. The products obtained by injection molding using HIPS are very brittle, and their cold resistance is even worse. Especially, they cannot be used in the environment of minus 40 degrees Celsius. Rapid aging, brittleness, bursting
On the other hand, when choosing HIPS injection molding products, it is difficult to demould, so it is necessary to improve

Embodiment 1

[0014] The production formula of cold-resistant HIPS particles, the production formula includes the following components in weight percentage, HIPS resin powder 85-95%, cold-resistant agent 2-6.5%, UV powder 0.5-1%, iron oxide black powder 0.5-1% and silicon steel powder 2-8%.

[0015] Among them, bis(2-ethylhexyl) adipate is selected as the cold-resistant agent, and the main component of the black iron oxide powder is ferric iron tetroxide. In this embodiment, each component in the production formula is mixed evenly and put into a granulator for processing to obtain cold-resistant HIPS particles. The granulation process by the granulator is a prior art, and will not be repeated here. The cold-resistant HIPS particles obtained in this example have extremely high cold-resistant performance, and the products injection-molded using cold-resistant HIPS particles are kept in an environment of minus 30 degrees Celsius for a long time. Demoulding helps to improve production efficien...

Embodiment 2

[0019] The production formula of cold-resistant HIPS particles, the production formula includes the following components in weight percentage, HIPS resin powder 85-89%, cold-resistant agent 4-6.5%, UV powder 0.5-1%, iron oxide black powder 0.5-1% and silicon steel powder 5-8%. This example is based on Example 1 to further narrow the range of the weight ratio of each component, according to the formulation of this implementation can obtain cold-resistant HIPS particles with the properties shown in Table 1.

Embodiment 3

[0021] The production formula of cold-resistant HIPS particles is composed of the following components in weight percentage, HIPS resin powder 85%, cold-resistant agent 6.5%, UV powder 1%, iron oxide black powder 1% and silicon steel powder 6.5%. This example is one of the specific formulations of the present invention, and cold-resistant HIPS particles with better performance as shown in Table 1 can be obtained according to the formulation of this implementation.

Abstract

The invention discloses a production formula of cold-resistant HIPS particles, which comprises the following components in percentage by weight: 85-95% of HIPS resin powder, 2-6.5% of cold-resistant agent, 0.5-1% of UV powder, and 0.5-1% of iron oxide black powder % and silicon steel powder 2 to 8%. The cold-resistant HIPS particles of the present invention have extremely high cold-resistant properties, greatly reduce their brittleness, that is, improve their physical properties such as tensile strength, flexural strength, and flexural modulus, and increase their toughness. In the environment of minus 40 degrees Celsius, it is not easy to age, not to become brittle, not easy to burst, and it is easy to demould when injection molding products, which helps to improve production efficiency and increase molding output.

Description

technical field [0001] The invention relates to the technical field of production formula of HIPS particles, in particular to a production formula of cold-resistant HIPS particles. Background technique [0002] High-impact polystyrene (HIPS) is an impact-resistant polystyrene product produced by adding polybutyl rubber particles to polystyrene. HIPS is cheap and has good impact resistance, but it also has very obvious shortcomings. The products obtained by injection molding using HIPS are very brittle, and their cold resistance is even worse. Especially, they cannot be used in the environment of minus 40 degrees Celsius. Aging rapidly, becoming brittle and developing cracks. On the other hand, when choosing HIPS injection molding products, it is difficult to demould, so it is necessary to improve. Contents of the invention [0003] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a production formula of cold-resistant HIPS ...
