Problems solved by technology

[0002] Plastic bottles are widely used because of their low cost of use and good performance. However, plastic bottles are generally made by blow molding, and their bodies are relatively thin, which makes them extremely susceptible to temperature effects during use. When it is high, it tends to soften and deform, which affects its use. Therefore, a heat-resistant plastic bottle is needed to expand its scope of use.

Abstract

The invention relates to a manufacturing method of a heat-resistant plastic bottle. The manufacturing method comprises the steps of 1 material preparing, 2 feeding, 3 embryo preparing, 4 molding, 5 demoulding, 6 disinfection, and 7 packaging. According to the invention, a high-temperature-resistant additive is added when the plastic bottle is prepared, so that the prepared plastic bottle is good in heat resistance, softening deformation caused by temperature rise is avoided, the application range is expanded, the manufacturing method is simple, and the production is convenient.

Description

technical field [0001] The invention relates to the technical field of plastic bottle production, in particular to a method for making a heat-resistant plastic bottle. Background technique [0002] Plastic bottles are widely used because of their low cost of use and good performance. However, plastic bottles are generally made by blow molding, and their bodies are relatively thin, which makes them extremely susceptible to temperature effects during use. When the temperature is high, it tends to soften and deform, which affects the use. Therefore, a heat-resistant plastic bottle is needed to expand its application range. Contents of the invention [0003] The invention aims to solve the deficiencies of the prior art, and provides a method for making a heat-resistant plastic bottle. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: [0005] A method for making a heat-resistant plastic bottle, comprising the follo...
