Les mat\u00e9riaux en silicone combinent les propri\u00e9t\u00e9s des mat\u00e9riaux organiques et inorganiques, pr\u00e9sentant de nombreuses caract\u00e9ristiques physiques et chimiques uniques, telles que non-toxiques et inodores, r\u00e9sistance aux intemp\u00e9ries, isolation \u00e9lectrique, r\u00e9sistance \u00e0 l'oxydation et aux rayons UV, faible \u00e9nergie de surface, inertie biologique, ignifugation et imperm\u00e9abilit\u00e9 \u00e0 l'eau, etc., qui sont largement utilis\u00e9es dans la d\u00e9fense nationale, le d\u00e9veloppement \u00e9nerg\u00e9tique, l'industrie l\u00e9g\u00e8re et alimentaire, le textile, la machinerie, la construction, le transport, l'industrie \u00e9lectrique et \u00e9lectronique, la m\u00e9dicale et pharmaceutique, les rev\u00eatements et peintures, la vie quotidienne et d'autres domaines.<\/span><\/span><\/span><\/span><\/span><\/span><\/span><\/span><\/span><\/span><\/p>\n

Actuellement, les produits de silicone de base peuvent \u00eatre divis\u00e9s en 4 cat\u00e9gories : le c\u0153ur du caoutchouc de silicone, l'huile de silicone, l'agent de couplage silane et les r\u00e9sines de silicone. Les r\u00e9sines de silicone ont, en g\u00e9n\u00e9ral, une meilleure r\u00e9sistance \u00e0 la chaleur que les r\u00e9sines organiques et poss\u00e8dent une rigidit\u00e9 di\u00e9lectrique sup\u00e9rieure ainsi qu'une r\u00e9sistance \u00e0 l'eau. Les r\u00e9sines de silicone peuvent \u00eatre divis\u00e9es en deux formes : poudre et liquide. Le liquide dissout g\u00e9n\u00e9ralement la r\u00e9sine de silicone dans diff\u00e9rents solvants chimiques avec peu d'odeur. Gr\u00e2ce \u00e0 l'excellente compatibilit\u00e9 avec de nombreuses r\u00e9sines organiques, les r\u00e9sines de silicone peuvent offrir une large gamme de films et de propri\u00e9t\u00e9s de performance pour de nombreuses applications \u00e0 haute valeur ajout\u00e9e.<\/span><\/span><\/span><\/span><\/span><\/span><\/span><\/span><\/span><\/p>\n

Le groupe organique R sert \u00e0 augmenter la compatibilit\u00e9 avec les autres composants pour l'effet \u00e9paississant, les liaisons SiO4\/2 am\u00e9liorent principalement la r\u00e9sistance du mat\u00e9riau composite pour l'effet de renforcement.<\/span><\/span><\/span><\/span><\/span><\/span><\/span><\/span><\/span><\/p>\n

R\u00e9sine de silicone typique \u2014 R\u00e9sine de silicone m\u00e9thyl MQ<\/span><\/span><\/b><\/span><\/span><\/span><\/p>\n

La r\u00e9sine de silicone MQ est une structure relativement unique de la r\u00e9sine de silicone avec un compos\u00e9 de silicone contenant une cha\u00eene de siloxane t\u00e9trafonctionnelle (SiO4\/2, Q) et des liaisons de cha\u00eene de siloxane monofonctionnelles (R3SiO1\/2, M), qui subit une r\u00e9action de co-hydrolyse-polycondensation pour former une structure sph\u00e9rique tridimensionnelle de graisse de silicone.<\/span><\/span><\/span><\/span><\/span><\/span><\/span><\/p>\n

<\/span>M Unit\u00e9<\/span><\/span><\/b><\/span><\/span><\/span><\/span><\/span><\/h3>\n

Utilis\u00e9 comme bloqueur de terminaison dans la formation des cha\u00eenes de siloxane ou pour terminer la croissance de la r\u00e9sine.<\/span><\/span><\/span><\/span><\/span><\/span><\/span><\/p>\n

<\/span>Applications \u2014 Adh\u00e9sif Sensible \u00e0 la Pression en Silicone<\/span><\/span><\/b><\/span><\/span><\/span><\/span><\/span><\/h3>\n

MQ silicone resin is a kind of silicone resin, which has a unique structure and excellent performance, primarily as a surface treatment agent and the silicone pressure-sensitive adhesive tackifiers, reinforcing fillers for silicone rubber, silicone antifoam agents, anti-blocking agents, heat resistant coatings, mold release agents, water repellent for construction and textile,\u00a0etc.<\/span><\/span><\/span><\/span><\/span><\/span><\/span><\/p>\n

 <\/p>\n

Silicone pressure-sensitive adhesive\u00a0is a special adhesive\u00a0made of silicone MQ resin, silicone rubber, catalyst, crosslinking agent and other additives. Silicone MQ resin mainly has the thickening reinforcing effect. A hydroxyl group or a vinyl resin in silicone MQ resin respectively synthesized with a hydroxyl group or the silicone rubber under the effect of the catalyst to produce the Silicone pressure-sensitive adhesive.<\/span><\/span><\/span><\/span><\/span><\/span><\/span><\/p>\n

 <\/p>\n

La qualit\u00e9 mol\u00e9culaire des r\u00e9sines MQ a un grand impact sur l'adh\u00e9sion des propri\u00e9t\u00e9s des adh\u00e9sifs sensibles \u00e0 la pression. Le changement mol\u00e9culaire modifie la viscosit\u00e9 et la force de coh\u00e9sion de l'adh\u00e9sif sensible \u00e0 la pression. Lorsque le poids mol\u00e9culaire est \u00e9lev\u00e9, les adh\u00e9sifs sensibles \u00e0 la pression pr\u00e9sentent une force de coh\u00e9sion \u00e9lev\u00e9e et une bonne viscosit\u00e9 ; tandis que lorsque le poids mol\u00e9culaire est faible, la viscosit\u00e9 en masse est faible, et l'adh\u00e9sion interfaciale peut \u00eatre am\u00e9lior\u00e9e, mais le polym\u00e8re a une faible force de coh\u00e9sion et risque de provoquer une rupture coh\u00e9sive lors du d\u00e9collement.<\/span><\/span><\/span><\/span><\/span><\/span><\/span><\/p>\n
