Abstract

The invention discloses addition fluorinated silicone rubber nano antifreezing adhesive paint and a preparation method thereof, belongs to the field of organic fluorinated silicon polymer materials, and overcomes the problems of the prior art that the coating curing temperature is high and the anti-icing effect is poor. The addition fluorinated silicone rubber nano antifreezing adhesive paint consists of a component A and a component B, wherein the component A comprises the following ingredients in parts by weight: 100 parts of vinyl-terminated polysiloxane, 30 to 50 parts of vinyl-terminated trifluoropropyl polysiloxane, 20 to 30 parts of nano particles and 20 to 30 parts of solvent; the component comprises the following ingredients in parts by weight: 9 to 12 parts of end hydrogen-containing silicone oil, 9 to 10 parts of end hydrogen-containing fluorine silicone oil, 20 to 30 parts of solvent, 0.0074 to 0.012 part of Karstedt catalyst, 0.05 to 1 part of defoaming agent and 1 to 2 parts of dispersing agent. The preparation method comprises the following steps of (1) uniformly mixing the ingredients according to the weight parts to obtain the component A, ball-milling the component A, and uniformly mixing the ingredients according to the weight parts to obtain the component B; (2) uniformly mixing the component A and the component B, uniformly smearing onto the surface of the workpiece which is coated with silane undercoat, and then curing the workpiece at room temperature. By adopting the paint, the anti-icing effect is good.

Description

technical field [0001] The invention relates to an addition-type fluorosilicone rubber nano antifreeze sticky coating and a preparation method thereof, belonging to the field of organic fluorosilicone polymer materials. Background technique [0002] Freeze sticking is a natural phenomenon under low temperature conditions. This natural phenomenon is a complex physical process involving the surface energy of solids, water vapor adsorption, condensation and freezing. [0003] The existing anti-freeze sticky technology is mainly divided into two categories: active deicing and passive deicing: (1) Manual or mechanical cleaning method: artificially use various tools or mechanical methods to knock the frozen sticky layer. Advantages: This method is easy to operate, The input cost is low. The disadvantage is that manual operation is intensive and inefficient. (2) Chemical reagent method: Use some components in chemical reagents to lower the freezing point of water and delay the fo...
