Description
The technical field is as follows:
the invention relates to a coating, in particular to an organic silicon transparent hard coating cured at room temperature and a preparation method thereof.
Background art:
silicone resins are thermosetting polysiloxane systems with a highly crosslinked structure. The prepolymer which is stable at room temperature is prepared by the hydrolysis/condensation of siloxanes with different functionality. When in application, the coating is sprayed on the surface of a base material and can be condensed and crosslinked into a hard organic silicon resin coating after being heated and cured. By introducing different side chain groups, organic silicon resins and coatings with different properties can be obtained, and the organic silicon resins and coatings are widely used for high and low temperature resistant insulating paint, special coating, adhesive, molding compound and the like. However, the silicone hard coating is often required to be cured into a film by heating, which causes great inconvenience to construction and is accompanied by great energy consumption.
In recent years, a large number of documents report that room temperature cured coatings are prepared by a sol-gel method using alkoxysilane, namely, the coatings are obtained by prehydrolysis/polycondensation of an alkoxysilane precursor, coating and room temperature drying. The obtained coating is an organic-inorganic hybrid coating, has the advantages of high hardness and good compactness, and can be used for scratch-resistant coatings, anticorrosion primers and the like. For example, patent CN103409063 discloses a room temperature cured silicone high temperature resistant coating, which uses triethylenetetramine as a room temperature curing agent to obtain a high temperature resistant opaque coating. Patent CN1752165 discloses an organosilicon transparent wear-resistant hardening coating, which mainly comprises tetraalkoxysilane, trialkoxysilane, dialkoxysilane and curing agent tetramethylammonium hydroxide, and the hardness after curing is only 6H.
The invention content is as follows:
in order to solve the problems that the organic silicon coating needs to be cured for a long time by heating, the hardness of the cured coating is lower and the adhesive force of the coating is poorer, the invention firstly makes a silane coupling agent react under an alkaline condition to obtain linear polysilsesquioxane, then makes the linear polysilsesquioxane and siloxane with different functionality undergo hydrolysis/condensation to obtain an organic-inorganic hybrid component A, and then makes the organic-inorganic hybrid component A, an alicyclic amine curing agent and a curing accelerator form a component B to be mixed, so that the coating is rapidly cured under the room temperature condition. Because the alicyclic amine contains alicyclic ring, such as cyclohexyl, hetero-oxygen hexacyclic ring, the alicyclic amine can be used as a curing agent to ensure that the prepared coating has low viscosity, long working life, high hardness after room temperature curing, good toughness, improved heat resistance and good chromaticity stability.
