Abstract

The invention relates to an addition type silicone rubber impression material, and belongs to the field of medical dental materials. The addition type silicone rubber impression material comprises the following raw materials by mass: 25-35 parts of vinyl polydimethyl siloxane, 1-10 parts of hydrosilicone oil, 1-5 parts of a catalyst, 3-10 parts of an enhancer, 55-65 parts of a compatibilizer, 0.1-3 parts of a hydrophilic modifier, 1-2 parts of a non-ionic surfactant, 0.1-0.5 part of indophenol, 0.1-1 part of benzoic acid alkyl ester, 0.1-1 part of a pigment, and 0.1-1.5 parts of peppermint oil. The addition type silicone rubber impression material comprises the non-ionic surfactant, namely nonylphenol polyoxyethylene ether, the hydrophobicity can be improved, and besides, the hydrophilic modifier can also enable all of the components to be uniformly dispersed and mixed, so that the impression is more accurate, and the detail reproduction is better.

Description

technical field [0001] The invention belongs to the field of medical dental materials, and in particular relates to an addition-type silicone rubber impression material. Background technique [0002] Dental impression materials are materials used to make impressions of teeth and soft and hard tissues of the oral cavity. An impression is a negative model of an object that records or reproduces the morphology of teeth and oral tissues and their relationship. According to whether the impression is elastic or not, it is divided into two types: elastic impression material and non-elastic impression material; according to whether the impression material can be used repeatedly, the impression material is divided into reversible impression material and irreversible impression Material: According to the form of solidification of impression materials, it can be divided into chemical coagulation, thermal coagulation and normal temperature setting. The chemical solidification type is ...
