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 embodiment 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, and B215 compound anti- Oxygen agent 2%. The specific pigment weight percentages are: carbon black 1.9%, color metallic luster effect pigment 56.2%, iridescent two-color pearl effect pigment 41.9%.

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

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

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

Embodiment 2

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

[0042] The above-mentioned raw materials are extruded and pelletized on a single-screw extruder to obtain a weather-resistant color co-extrusion special material with silver pearlescent decorative effect. The production process and process are basically the same as in Example 1.

[0043] The technical effects are as follows:

[0044] ①After processing into a film, it can be observed to have a shiny appearance with a silver pearl effect

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

Embodiment 3

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

[0048] In the preparation method, 2,6-dihydroxyacetophenone and B215 are added at the same time. The rest is the same as in Example 1.

[0049] The technical effects are as follows:

[0050] ①Glossiness≤20;

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

Description

Technical field [0001] The invention belongs to a weather-resistant color co-extrusion special material for PVC and a manufacturing method thereof, and particularly belongs 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 energy conservation of doors and windows is an important part of it. PVC plastic doors and windows profiled material, because its PVC material has a very low thermal conductivity coefficient, which is similar to wood, so under the same structure, the energy-saving effect of the finished doors and windows is significantly better than that of other materials, and the cost is low. The consumption of plastic doors and windows has been increasing year by year, and the profiled materials of PVC plastic doors and windows have also developed rapidly. [0003] With the ...
