Problems solved by technology

[0003] The shell of outdoor colored lights is generally made of PVC. After being placed underwater for a long time, the color of the shell will gradually turn yellow, which is called yellowing phenomenon. This phenomenon will affect the light effect of outdoor colored lights displayed through the shell, and needs to be improved.

Abstract

The invention relates to the field of PVC, and particularly discloses an anti-aging and algae-resistant PVC composition for outdoor colored lamps and a preparation method of the anti-aging and algae-resistant PVC composition. The aging-resistant and algae-resistant PVC composition for the outdoor colored lamps is prepared from the following raw materials: PVC, a plasticizer, a sericite powder-(1-cyclobutene-1-carboxylic acid)-acetic acid isopropenyl ethyl ester compound, CPE135A, a stabilizer, Sb203, a hindered phenol antioxidant, a hindered amine light stabilizer and a lubricant. The preparation method comprises the steps of stirring and mixing the raw materials, extruding, and granulating to obtain the PVC composition. The sericite powder-(1-cyclobutene-1-carboxylic acid)-acetic acid isopropenyl ethyl ester compound is adopted, the sericite powder has a shielding effect on ultraviolet rays, and the sericite powder and acetic acid isopropenyl ethyl ester are connected through the 1-cyclobutene-1-carboxylic acid, so that the water resistance of the PVC composition is improved; and unreacted carbon-carbon double bonds in the sericite powder-(1-cyclobutene-1-carboxylic acid)-acetic acid isopropenyl ethyl ester compound can destroy the conjugated structure of the PVC, so that the yellowing resistance of the PVC composition is improved.

Description

technical field [0001] The present application relates to the field of PVC, more specifically, it relates to an anti-aging and algae-resistant PVC composition for outdoor colored lights and a preparation method thereof. Background technique [0002] Colored fountains can be used to adjust air humidity and purify the air. It is one of the scenic spots to beautify the city and is deeply loved by people. Generally, the effect of colored fountains is achieved by installing outdoor colored lights under the fountains. [0003] The shell of outdoor colored lights is generally made of PVC. After being placed underwater for a long time, the color of the shell will gradually turn yellow, which is called yellowing phenomenon. This phenomenon will affect the light effect of outdoor colored lights displayed through the shell, and needs to be improved. . Contents of the invention [0004] In order to improve the problem that the shell of the outdoor colored lamp is prone to yellowing, ...
