Problems solved by technology

[0002] At present, most of the downpipes on external walls are made of PVC, and the colors are mainly white, brown, and gray. They have the following disadvantages: 1. Poor weather resistance. After several years of use, they tend to fade, change color, age, and decrease in strength; 2. If If you want to imitate the appearance of copper, you need to spray paint, but the combination of paint and PVC resin is not good, and a large area of ​​peeling will occur after a period of use

Embodiment 1

[0014] Embodiment 1 prepares the weather-resistant rain downpipe of imitation copper effect,

[0015] The raw materials are as follows: copper gold powder 1.5%, silver powder 2%, pearl powder 3%, lubricant 0.5%, antioxidant 0.5%, and the balance is matrix resin ASA.

[0016] The lubricant is selected from PE wax.

[0017] The antioxidant is selected from AO-18 antioxidants.

[0018] The preparation method is a conventional method.

[0019] The rain downpipe prepared above has the color of metallic copper, has silver imitation effect and pearlescent effect, and does not need additional spraying treatment during use. It can be used outdoors for a long time, and has good weather resistance. After several years of use (more than two years of outdoor exposure for a long time), there will be no fading, discoloration, aging, and loss of strength.

Embodiment 2

[0020] Embodiment 2 prepares the weather-resistant rain downpipe of imitation copper effect,

[0021] The raw materials are as follows: copper gold powder 1%, silver powder 4%, pearl powder 1%, lubricant 1%, antioxidant 1%, and the balance is matrix resin; ASA.

[0022] The lubricant is selected from oleic acid amide.

[0023] The antioxidant is selected from UV ultraviolet absorbers.

Embodiment 3

[0024] Example 3 Prepare a weather-resistant rain downpipe with copper-like effect,

[0025] The raw materials are as follows: copper gold powder 2%, silver powder 1%, pearl powder 4%, lubricant 0.1%, antioxidant 0.1%, and the balance is matrix resin ASA.

[0026] The lubricant is selected from erucamide.

[0027] The antioxidant is selected from PS-2 phosphate auxiliary antioxidants.

Abstract

The invention discloses a weather-proof down pipeleader with copper imitating effect. The weather-proof down pipeleader with the copper imitating effect is prepared from the following raw materials in percentage by weight: 1-2% of copper gold powder, 1-4% of silver powder, 1-4% of pearl powder, 0.1-1% of a lubricating agent, 0.1-1% of an antioxidant and the balance of matrix resin ASA, wherein the lubricating agent is one or more than two of PE wax, oleamide and erucamide, and the antioxidant is one or more than two of an AO-18 antioxidant, a PS-2 phosphate ester type auxiliary antioxidant, an HALS-1 / HALS-3 hindered amine type compound stabilizer and an UV absorbent. The down pipeleader disclosed by the invention has metallic copper color, has silver imitating effect and pearl effect, can be used without carrying out extra spraying treatment, can be used outdoors for a long time, has good weather resistance and does not fade, discolor or age and is not reduced in strength after being used for a few years later.

Description

technical field [0001] The invention relates to a weather-resistant and rain-resistant downpipe with an imitation copper effect, belonging to the technical field of pipes. Background technique [0002] At present, most of the downpipes on external walls are made of PVC, and the colors are mainly white, brown, and gray. They have the following disadvantages: 1. Poor weather resistance. After several years of use, they tend to fade, change color, age, and decrease in strength; 2. If If you want to imitate the appearance of copper, you need to spray paint, but the combination of paint and PVC resin is not good, and a large area of ​​peeling will occur after a period of use. Contents of the invention [0003] Aiming at the above-mentioned prior art, the present invention provides a weather-resistant rain downspout with copper imitation effect. The rain downpipe of the present invention is the color of metallic copper, has imitation silver effect and pearlescent effect, does n...
