Problems solved by technology

[0006] Another disadvantage of PVC plastic door and window profiles is that the product has a single hue, mainly white, and the decorative effect is poor, which cannot meet the diverse needs of decoration. This is very good for aluminum alloy door and window profiles. , electrostatic spraying and other technologies make the surface of the profile rich in color; if the whole body coloring of PVC plastic profile is carried out, he will face a problem that has been insurmountable in the industry, that is, fading, the brighter the color, the faster the fading occurs, construction The Ministry of Foreign Affairs has stipulated that the outdoor application of colored PVC plastic profiles should be restricted.
However, none of the existing technologies can simultaneously solve the three problems of long-term weather resistance, long-term color stability, and lustrous pearlescent effect of PVC plastic door and window profiles, decorative panels, and scrapers. The color difference △E of the paint after aging is often greater than 6 , △b is greater than 4

Embodiment 1

[0032] This example provides a weather-resistant color co-extrusion special material with bronze pearlescent decorative effect, which contains 92.7% of base material LI970 ASA, 1.3% of pigment, 3% of UV770DF light stabilizer, 1% of UV326 ultraviolet absorber, B215 compound anti- Oxygen 2%. The specific weight percentages of the pigments are: 1.9% of carbon black, 56.2% of colored metallic luster effect pigments, and 41.9% of iridescent two-color pearl effect pigments.

[0033] The preparation method of the above-mentioned weather-resistant color co-extrusion special material with pearlescent decorative effect comprises the following steps:

[0034] (1) Weighing: Weigh base materials, pigments, stabilizers, UV absorbers, and antioxidants according to the formula.

[0035] (2) Mixing: In order to make it mix evenly, first mix the pigment, stabilizer, UV absorber, and antioxidant evenly, then add the base material and mix evenly in a low-speed mixer. The mixing time is 10~15min....

Embodiment 2

[0041] This example provides a weather-resistant color co-extrusion special material with silver pearlescent decoration effect and its preparation method. The weight percentage of its components is: base material V150 90.3%, pigment 3.7%, UV770DF light stabilizer 3%, UV326 UV absorber 1%, B215 compound antioxidant 2%. The specific weight percentages of the pigments are: 81.6% of the silver-white pearl luster effect pigment, and 18.4% of the aluminum powder.

[0042] Extrude and granulate the above raw materials on a single-screw extruder to obtain a weather-resistant color co-extrusion special material with a silver pearlescent decorative effect. Production procedure and technology are basically the same as Example 1.

[0043] Its technical effect is as follows:

[0044] ①After being processed into a film, the shiny appearance can be observed, with a silver pearlescent effect

[0045] ②Color difference after aging △E≤5, △b≤3 (Method A in GB / T 16422.2-1999, test for 6000h) ...

Embodiment 3

[0047]This example provides a weather-resistant color co-extrusion special material with silver pearlescent decoration effect and its preparation method. The weight percentage of its components is: base material V150 89.3%, pigment 3.7%, UV770DF light stabilizer 3%, UV326 UV absorber 1%, B215 compound antioxidant 2%. The specific weight percentages of the pigments are: 81.6% of the silver-white pearl luster effect pigment, 18.4% of the aluminum powder, and 1% of 2,6-dihydroxyacetophenone.

[0048] In the preparation method, 2,6-dihydroxyacetophenone and B215 are added simultaneously. All the other are identical with embodiment 1.

[0049] Its technical effect is as follows:

[0050] ① gloss ≤ 20;

[0051] ②Color difference after aging: △E≤4, △b≤2 (method A in GB / T 16422.2-1999, test for 6000h).

Abstract

The invention discloses a weather resistant type color co-extruding dedicated material with pearly-luster decoration effect and a manufacturing method thereof. The coating contains base stock, pigment, a flatting agent, a light stabilizer, an ultraviolet absorber and an antioxidant. Compared with the prior art, the material has the characteristics of being gorgeous in color and high in weather resistance.

Description

technical field [0001] The invention belongs to a special weather-resistant color co-extrusion material for PVC and a manufacturing method thereof, in particular to a weather-resistant color co-extrusion special material with a pearlescent decorative effect and a manufacturing method thereof. Background technique [0002] Affected by energy shortages, building energy conservation has attracted much attention, and door and window energy conservation is an important part of it. PVC plastic door and window profiles, because of the extremely low thermal conductivity of PVC material, which is similar to wood, so under the same structure, the energy-saving effect of the finished doors and windows is obviously better than that of other materials, and the cost is low. The consumption of plastic doors and windows is increasing year by year, and PVC plastic doors and windows profiles are also developing rapidly. [0003] With the improvement of living standards, people's demand for r...
