Embodiment 1～2

[0059] Embodiments 1-2 provide a series of organosilicon vegetable oil-based polyols, which are respectively prepared by using different carboxyl group-containing organosilicon ring-opening epoxidized soybean oil, and the specific process is as follows.

[0060] Add the carboxyl group-containing organosilicon monomer into the reaction flask, pass through nitrogen protection, then heat to 80-120°C, drop in epoxidized vegetable oil in proportion, extract the product with ethyl acetate, and use anhydrous magnesium sulfate or anhydrous Na2SO4 dried. The product was filtered and rotary evaporated to remove ethyl acetate, then dried under vacuum at 45 °C overnight to obtain a vegetable oil-based polyol with low surface energy silicone in the side chain. Concrete preparation conditions are as shown in table 2, and reaction scheme is as follows figure 1 shown.

Embodiment 3～4

[0062] Embodiments 3-4 provide a series of organosilicon vegetable oil-based polyols, which are prepared by ring-opening reaction of epoxidized vegetable oil and hydroxyl-containing organosilicon with different structures, and the specific process is as follows.

[0063] Add the hydroxyl-containing organosilicon monomer and catalyst into the reaction flask, mix well, then heat to 40-80°C, drop in epoxidized vegetable oil in proportion, continue the reaction for 20-120min, extract the product with ethyl acetate, and use Dry over magnesium sulfate or anhydrous sodium sulfate. The product was filtered and rotary evaporated to remove ethyl acetate, then dried under vacuum at 45 °C overnight to obtain a vegetable oil-based polyol with low surface energy silicone in the side chain. Concrete reaction conditions are as shown in table 1, and reaction scheme is as follows figure 2 shown.

Embodiment 5～6

[0065] Embodiments 5-6 provide a series of silicone vegetable oil-based polyols, which are prepared by ring-opening reaction of epoxidized soybean oil and amino group-containing silicones of different structures, and the specific process is as follows.

[0066] Add hydroxyl-containing organosilicon monomers and catalysts into the reaction flask, mix well, then heat to 40-80°C, drop in epoxidized vegetable oil in proportion, and continue the reaction for 60 minutes. The product is extracted with ethyl acetate and washed with anhydrous sulfuric acid magnesium or anhydrous sodium sulfate. The product was filtered and rotary evaporated to remove ethyl acetate, then dried under vacuum at 45 °C overnight to obtain a vegetable oil-based polyol with low surface energy silicone in the side chain. The specific reaction conditions are shown in Table 1, and the reaction scheme is as follows: image 3 shown.

Abstract

The invention provides an organosilicon vegetable oil-based polyol, and the organosilicon vegetable oil-based polyol is prepared by the following steps: carrying out an epoxy ring-opening reaction on epoxidized vegetable oil and an organosilicon monomer to obtain the organosilicon vegetable oil-based polyol, wherein the structural formula of the organosilicon monomer is shown in the specification, R is methyl or ethyl, R1 is one of alkyl, substituted alkyl or hetero-alkyl, and R2 is one of hydroxyl, amino or carboxyl. The invention also provides an application of the organosilicon plant oil-based polyol. Compared with the prior art, the preparation method has the advantages that the specific raw materials are subjected to the epoxy ring-opening reaction, the organic silicon is coupled to the side chain of the fatty acid of the vegetable oil to obtain the organic silicon vegetable oil-based polyol with antifouling activity, the preparation process is simple and easy to control, and industrial production is convenient to realize. The prepared organic silicon vegetable oil-based polyol has a polyhydroxy structure with a cross-linking effect and a low surface energy structure for preventing viscosity of microorganisms and proteins, and is in a liquid state at normal temperature.

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to a silicone vegetable oil-based polyol, a preparation method and application thereof. Background technique [0002] Biofouling substances such as proteins, cells, microorganisms, and aquatic organisms are easy to adhere and accumulate on the surfaces of daily necessities, building materials, biomedical materials, and marine equipment, which brings a series of problems to the medical and health, food, and shipping industries, seriously threatening human health and property safety. Among them, marine biofouling increases the navigation resistance of ships, blocks marine engineering facilities, and even causes local perforation and corrosion of substrates, affecting the service performance and service life of marine engineering facilities. In addition, the process of cleaning up marine pollutants may also cause biological invasion, epidemic spread, etc., resulting in eco...
