The invention patent CN103655212B discloses a room temperature addition silicone rubber putty type oral cavity impression material applied to a primary impression, which is prepared by blending two components, namely a matrix component and a catalytic component, wherein the matrix component consists of vinyl silicone oil containing more than two vinyl functional groups, hydrogen-containing silicone oil containing more than three Si-H functional groups, a compatibilizer, a reinforcing agent and other auxiliary agents according to a certain proportion. The catalytic component consists of vinyl silicone oil containing more than two vinyl functional groups, a catalyst which is a complex of chloroplatinic acid and the vinyl silicone oil, a compatibilizer, a reinforcing agent and other auxiliary agents according to a certain proportion. The invention has reasonable formula and easy operation, the cured material has elastic recovery of 99.8 percent, the curing time is 3-5min, the Shore hardness is about 65, and the fine duplication is 0.02mm and can be clearly seen, so that the invention can be used for manufacturing accurate dental crowns, dental bridges, false teeth, occlusion records and oral cavity tissue impression taking. But the material of the invention is not soft enough, is not easy to mix and has lower comfort level when entering the mouth; and the use of the general formula in winter and summer can not accurately control the internal curing time under the conditions of both low temperature in winter and high temperature in summer, and the user experience is poor.
The invention patent CN111053698A discloses an oral cavity impression material, which comprises: a catalyst component and a matrix component; the catalyst comprises the following components in parts by weight: 15-40 parts of vinyl silicone oil, 0.5-20 parts of silicone resin, 55-80 parts of reinforcing filler and 0.5-1.5 parts of platinum catalyst; the matrix comprises the following components in parts by weight: 5-25 parts of vinyl silicone oil, 0.5-20 parts of silicone resin, 55-80 parts of reinforcing filler and 5-20 parts of hydrogen-containing silicone oil. The oral cavity impression material is prepared from a catalyst and a matrix, wherein the matrix comprises a base polymer and a cross-linking agent, the catalyst comprises the base polymer and the catalyst, vinyl silicone oil and silicone resin are used as base substances, hydrogen-containing silicone oil is used as the cross-linking agent, and reinforcing fillers are added into the two components, so that the prepared impression material can accurately record occlusion relation and overcomes the defects of low hardness, easy deformation and breakage. But the invention also has the problems of uneasy mixing and low comfort in entrance. Although the material of the invention uses the silicone resin as the reactive filler, the hardness of the material before curing is reduced to a certain extent, but the material is still not soft enough, is not easy to mix and has lower comfort level when entering the mouth; and still use general formula in winter and summer, can't accurately control giving consideration to intraoral curing time under winter low temperature and summer high temperature situation, user experience is relatively poor.
