Abstract

The invention belongs to the field of macromolecular materials, and relates to an anti-fog and dripping composition containing polyol fatty acid ester and a preparation method thereof. In order to overcome the technical deficiencies of the anti-fog and dripping agents in the prior art, which have high temperature resistance and poor compatibility with resins, the present invention provides an anti-fog and drip composition containing polyhydric alcohol fatty acid ester, which is composed of unit alcohol polyhydric Pentaerythritol fatty acid ester and pentaerythritol fatty acid ester. The anti-fog and dripping agent prepared by mixing and melting the two liquid phases not only has excellent anti-fog and dripping performance, but also has the advantages of high temperature resistance and good compatibility with resins. It is suitable for plastic processing Field promotion and application.

Description

technical field [0001] The invention belongs to the field of macromolecular materials, and relates to an anti-fog and dripping composition containing polyol fatty acid ester and a preparation method thereof. Background technique [0002] Dripping agents and anti-fogging agents are generally compounded by a variety of ester compounds. These compounds are composed of hydrophilic groups and hydrophobic groups. After adding dripping agents and anti-fogging agents to plastic films, their molecular movements can be Through the gradual migration of the non-crystalline area inside the plastic to the surface of the film for directional alignment, the hydrophilic groups of the dripping agent and anti-fogging agent molecules are automatically arranged on the outside of the film, toward the side of the air, while the hydrophobic groups are automatically arranged on the inside of the film. Forms a hydrophilic film. Anti-fog agents can be divided into two categories according to the meth...
