Abstract

The invention discloses a foamed polystyrene curtain plate sheet and a manufacturing method thereof. The foamed polystyrene curtain plate sheet consists of the following components in part by weight: 100 parts of polystyrene, 1 to 50 parts of blended resin, 1 to 50 parts of filler, 0.1 to 20 parts of compatilizer, 0 to 1 part of antioxidant, 0 to 5 parts of processing aid, 0.1 to 10 parts of foaming agent and 0.1 to 10 parts of cross-linking agent. The foamed polystyrene curtain plate sheet manufactured according to a formula of the invention has light weight, aging resistance, corrosion resistance, heat insulation and insulating property, and the most outstanding advantage of high thermal deformation resistance, and can adapt to direct sunlight under a hot weather condition in summer in low-latitude regions. The manufacturing method of the foamed polystyrene curtain plate sheet is simple and practical, and has wide application prospect.

Description

technical field [0001] The invention relates to the field of curtain panels, in particular to a foamed polystyrene curtain panel and a preparation method thereof. Background technique [0002] Curtain panels are usually prepared from plastic materials, aluminum materials, and wood. Aluminum has high mechanical strength, but the production process is easy to pollute the environment and cause harm to the human body; wood texture is better, but it requires higher requirements for the required wood, and at the same time has poor strength, requires a certain thickness, and is more expensive; plastic materials can Overcome the shortcomings of aluminum and wood, and obtain thin and flexible sheets. After being heated and melted, plastic material curtain panels can be processed by traditional processes such as extrusion and injection molding, which are easy to produce quickly and automatically. Widely favored. Expanded polystyrene plastic curtain panels are light in weight, aging-...
