Problems solved by technology

[0005] 1. There are no relevant standards for plastic materials, product quality varies, and some products do not meet environmental protection requirements
[0006] 2. There are no industry standards for weather resistance, such as light aging and waterproof performance, and there are no quantitative indicators. Products generally have poor weather resistance and are prone to aging and damage, resulting in waste of resources
Products do not meet international environmental protection requirements
[0008] 4. Low molecular weight stearic acid is used as lubricant, which is easy to precipitate, resulting in poor appearance and poor weather aging resistance
[0009] 5. The service life is short, and it will appear aging after 4-6 months outdoors

Abstract

The invention discloses a formula of a transparent polyvinyl chloride section bar applied in an LED rainbow strip light. A core line material comprises the components of, by weight: 100 parts of PVC resin powder, 60 parts of a plasticizer, 1.5 parts of a heat stabilizer, 0.4 parts of an external lubricant, and 0.2 parts of an internal lubricant. A coating material comprises the components of, by weight: 100 parts of PVC resin powder, 60 parts of a plasticizer, 2.2 parts of a heat stabilizer, 0.4 parts of an external lubricant, 0.2 parts of an internal lubricant, and 0.25 parts of an ultraviolet light absorber. According to the invention, the two-step formed LED rainbow strip light plastic material does not contain heavy metal or phthalate ester, and satisfies current international environmental standards. The material has excellent weathering resistance. The material is not whitened on contacting water, and is resistant to vulcanization contamination.

Description

【Technical field】 [0001] The invention relates to a transparent polyvinyl chloride profile formula, in particular to a transparent polyvinyl chloride profile formula applied to LED rainbow light strips. 【Background technique】 [0002] LED light strips (LED rainbow lights) are widely used in lighting engineering, festival decoration, decorative lighting modeling and other fields. Transparent soft PVC material, because of its high transparency, good full diffusion performance, and easy processing, is widely used in the production of LED strips by extrusion molding. [0003] The most commonly used production process for PVC LED strips is the secondary molding process: the first step is to co-extrude tinned copper wire and PVC plastic as the lead wire and carrier of the LED. Punch holes on the wires and install LED lamp beads. Made into the core wire of the LED strip. In the second step, the core wire prepared in the first step is covered with a layer of sealed pipeline.
