Problems solved by technology

[0004] Existing bites generally use styrene-butadiene rubber, TPE or TPR (poor resilience and bite resistance)
Styrene-butadiene rubber has high raw material cost, difficult production, and sharp cutting end, which is not easy to form
TPE or TPR has poor resilience and poor bite resistance

Abstract

The invention provides a high-performance orthodontic bite and a preparation method thereof, which is prepared from the following raw materials in parts by weight: 60-80 parts of silica gel, 10-30 parts of modified nano filler, and organosiloxane modified butyl styrene 10-20 parts of rubber, 10-25 parts of maleic anhydride grafted hydrogenated styrene-butadiene block co-extract, 1-5 parts of vulcanizing agent, and 1-3 parts of crosslinking agent. According to the test results, the rubber bite prepared by the present invention has good mechanical strength, and the compression permanent deformation test results show that the rubber bite has good deformation resistance and good resilience. The method has simple process and convenient operation, can save a large amount of manpower and material resources, is low in cost, produces no toxic irritating smell during the preparation process, is safe and environment-friendly, and the obtained chew has high resilience and strong bite resistance. Therefore, the method of the present invention has wide application prospects in the field of chewing gum.

Description

technical field [0001] The invention belongs to the technical field of orthodontic materials, and in particular relates to a high-performance orthodontic bite and a preparation method thereof. Background technique [0002] Bite is a silicone rod that is used in conjunction with invisible braces. The use of bites can make the invisible braces fit better with the teeth, ensuring the balance of the entire orthodontic force system during orthodontics. Therefore, the use of chewing gum mainly has the following functions: 1. Make the invisible braces fit better. Grinding can eliminate the gap between the braces and the teeth, making the braces more invisible and making the gap smaller; 2. Preventing the occurrence of braces face , because the teeth will be a little sore and soft after wearing braces, and it is troublesome to take off the braces when eating, etc., which will lead to eating less food than usual, and the use of chewing function will also be reduced, which may lead to...
