Embodiment 1

[0045] Embodiment 1 Preparation of organosilicon-modified cardanol polyglycidyl ether resin

[0046] Mix 60 parts of cardanol polyglycidyl ether resin with 15.2 parts of xylene, the solution is a uniform light yellow transparent liquid, add 1 part of stannous octoate, 20 parts of silicone resin, and 3.8 parts of cyclohexanone and stir to raise the temperature at 80~ React at 100°C for 8-10 hours. 100 parts of transparent homogeneous viscous organosilicon-modified cardanol polyglycidyl ether resin were obtained. Measured by infrared absorption spectrum at 1128cm -1 、1095cm -1 and 1022cm -1 The characteristic absorption peak of the silicon-oxygen bond appears, and the 3400cm -1 and 1000cm -1 The characteristic absorption peaks of the nearby carbon hydroxyl and silicon hydroxyl groups are weakened, which proves that the corresponding target product is obtained through the synthesis reaction.

Embodiment 2

[0048] Anti-corrosion and heat-resistant primer, weighing 100 parts by weight of organosilicon modified cardanol polyglycidyl ether resin (embodiment 1), 100 parts by weight of solvent, stirring with a high-speed mixer in a stainless steel tank, adding 0.5 parts by weight of defoamer BYK066N 1. The thixotropic agent is 2.5 parts by weight of organic bentonite, after stirring evenly with the resin, add 40 parts by weight of mica iron oxide, 15 parts by weight of aluminum powder, 20 parts by weight of aluminum tripolyphosphate, 15 parts by weight of precipitated barium sulfate, and 10 parts by weight of light calcium carbonate. The parts by weight are stirred evenly, then ground to a standard fineness with a sand mill or a three-roll mill, filtered and packaged as component A of the coating.

Abstract

The invention relates to an organic silicon modified cardanol polyglycidyl ether resin, and also provides a high-temperature-resistant anticorrosive coating composition containing the organic siliconmodified cardanol polyglycidyl ether. According to a preparation method, cardanol is introduced onto the main chains of organic silicon resin, so that the organic silicon modified cardanol polyglycidyl ether resin has the heat resistance, weather resistance and flexibility of rganic silicon resin, and retains the properties of convenience in construction and the like caused by normal-temperature curing and high cross-linking property, as well as the specific properties of mechanical properties, chemical resistance and the like.

Description

technical field [0001] The invention relates to a cardanol polyglycidyl ether resin and a preparation method thereof. [0002] The present invention also relates to the above-mentioned organosilicon-modified cardanol polyglycidyl ether resin and a preparation method thereof. [0003] The present invention also relates to a room temperature curing high temperature resistant anti-corrosion coating prepared from the above organosilicon modified cardanol polyglycidyl ether resin. Background technique [0004] Metal equipment operating at high temperatures in ocean or high humidity environments must withstand thermal oxidation corrosion at high temperatures, and must withstand liquid medium and electrochemical corrosion at room temperature when the equipment stops. Therefore, it must be protected against corrosion. Among many high-temperature resistant and anti-corrosion measures (new alloys, ion implantation, improved processes, surface protection layers, etc.), organic coating...
