Technical Field

[0001] The invention relates to the technical field of composite additives, in particular to a composite additive for plastic packaging materials for construction. Background Art

[0002] Additives are excipients and additives used in the production of medicines, plastics, coatings, and alloy materials. They are auxiliary chemicals added to improve the production process, increase product quality and output, or give the product some unique application properties. Additives are also called additives. As the name suggests, composite additives refer to additives composed of multiple additives fused together. Composite additives have most of the advantages of component additives and can reduce the cost of use in the production of medicines, plastics, coatings, and alloy materials.

[0003] During the production of existing plastic products, additives need to be added one by one, which increases the production process, resulting in increased production time and reduced production efficiency. Alternatively, composite additives are added to the plastic raw materials during the production of plastic products. The excessively high temperature during the preparation of the plastic product raw materials will lead to reduced performance of the composite additives and affect the melting rate of the plastic raw materials. Therefore, it does not meet the existing needs. In this regard, we have proposed a composite additive for plastic packaging materials for construction. Summary of the invention
