Abstract

The application relates to the field of degradable polymer materials, and specifically discloses an environment-friendly biodegradable SBS raw material and a preparation method thereof. The environment-friendly biodegradable SBS raw material is characterized in that it is composed of the following components in weight percentage: styrene-butadiene-styrene block copolymer 40-55%; styrene-ethylene-butylene-styrene block Copolymer 10‑25%; mineral oil 15‑20%; additives 0‑5%; biological enzyme balance. The composition / product of the present application The composition can be used to manufacture skin tissues, skin-friendly toys, imitation silicone products and bionic products, and has the advantages of degradability and high degradation efficiency.

Description

technical field [0001] The application relates to the field of degradable polymer materials, more specifically, it relates to an environment-friendly biodegradable SBS raw material and a preparation method thereof. Background technique [0002] SBS, or styrene-butadiene-styrene block copolymer, is a thermoplastic elastomer with the largest output in the world and the most similar performance to rubber. It has both the characteristics of plastic and rubber; it has a huge consumer market. [0003] Synthetic plastics are used in a huge amount in daily life, and at the same time, we need to face the environmental problems brought about by synthetic plastic products: synthetic plastics are difficult to degrade and disappear in nature. With the popularization of the concept of sustainable development, people pay more and more attention to environmental issues, and more and more consumers begin to respect and use degradable environmental protection materials, but there are few degr...
