Problems solved by technology

In this way, the existing products still have high cost, low temperature impact resistance, poor dimensional stability, hardness and flame retardancy compared with plastics added with nano-scale active light calcium carbonate.
In addition, the way of adding nano-scale active light calcium carbonate to existing PVC plastic products is to add nano-scale active light calcium carbonate to the plastic pellets in advance, which is a typical in-situ polymerization method. , the addition of nano-scale light active calcium carbonate cannot meet the needs of various plastic profile manufacturers, and cannot bring economic benefits to profile manufacturers. Therefore, it is difficult to implement promotion in profile manufacturers, and there is no corresponding Plastic door and window profile available

Embodiment Construction

[0024] The present invention will be further described below in conjunction with specific examples. The present invention adds nano-scale active light calcium carbonate PVC door and window profiles, and replaces the impact modifier in ordinary PVC door and window profiled materials with nano-scale active light calcium carbonate: chlorine Polyethylene or ACR impact modifier and ordinary active light calcium carbonate, and PVC, ACR processing aids, heat stabilizers, titanium dioxide are added at the same time as the above calcium carbonate.

[0025] Its weight ratio is: PVC100, 100, 100, ACR processing aid 1, 1.5, 2.5, heat stabilizer (organic tin, compound salt, rare earth) 2, 3, 5.6, titanium dioxide 4, 4.5, 5, nano-scale Active light calcium carbonate 3, 14, 25.

[0026] The nano-scale active light calcium carbonate is made by the following method: under the high-speed stirring of 400-800 rpm, the digestion reaction is carried out with water and calcium oxide, and then carbon...

Abstract

A PVC section for door or window is characterized by that it conains nano-class active light calcium carbonate, instead of the polyvinylchloride or ACR as anti-impact modifier and ordinary active light calcium carbonate. Its advantages are low cost, and high size stability, low-temp anti-impact performance, hardness and flame-retarding nature.

Description

technical field [0001] The invention relates to a plastic profile added with nanometer materials, in particular to a PVC door and window profile added with nanoscale active light calcium carbonate, a manufacturing method thereof and equipment for implementing the method. technical background [0002] The technology of adding nano-scale active light calcium carbonate to the existing PVC door and window profiles is outstanding: the worldwide problem that nano-scale active light calcium carbonate is not easy to disperse and mix unevenly in the thermal mixer. Therefore, there is no PVC door and window profiles with nano-scale active light calcium carbonate added. In order to ensure the mechanical strength of the product, existing products have to add impact modifiers, such as chlorinated polyethylene (CPE) or ACR impact modifiers and ordinary active light calcium carbonate. Like this, compared with the plastic that adds nanoscale active light calcium carbonate, existing product...
