Problems solved by technology

In the past, plastic manufacturers produced plastic products through their own procurement of raw materials and appropriate preparations. Not only was the product quality difficult to maintain and controllable, but the quality was uneven, but they also raised challenges in all links including procurement of raw materials, production and processing, quality inspection, and warehousing. Strict requirements greatly increase production costs

Description

technical field [0001] The invention belongs to the field of plastic processing, and in particular relates to a halogen-free environment-friendly and weather-resistant color master batch and a preparation method thereof. Background technique [0002] Plastics are susceptible to aging due to environmental and climatic factors. Plastics appear yellowing, discoloration, hardening, and cracks, which in turn cause physical properties such as impact resistance, tensile strength, and elongation to be greatly reduced, thereby affecting the normal use of plastics. Adding halogen to plastic materials cannot be recycled, and it will release harmful substances dioxins during burning and heating, which threatens human health and the ecological environment. With the rapid development of the plastic industry and the continuous improvement of plastic performance, plastic products have been more widely used. At the same time, the requirements for halogen-free environmental protection and wea...
