Embodiment 1
[0032] A coating for high temperature resistant shoes, the coating is composed of a bottom coating and a surface coating, the bottom coating is composed of a bottom layer, a high temperature resistant reaction layer, and a heat insulation layer, and the surface coating is composed of a surface protection layer.
[0033] The surface protection layer is organic high temperature resistant fiber and polymer emulsion and the described temperature resistant binder is alkaline silica sol. The requirements of the silica sol are that the particle size distribution is 10-20nm, the sodium ion content is less than 0.4%, the SiO2 content is not less than 40%, the Ph is 8.5-10.5, and the viscosity is 10-30mpas; in the present invention, the performance of the silica sol is high temperature coating The key to the layer, silica sol with low content of SiO2 shows lower cohesiveness, and the particle size distribution affects the penetration ability of silica sol particles in leather fibers.

Abstract
The invention relates to a high-temperature-resistant coating for labor insurance shoe uppers and a preparation method thereof, in particular to a high-temperature-resistant shoe coating and a preparation method thereof. The coating is composed of a temperature-resistant adhesive, a temperature-resistant reactive filler, an insulating It is composed of heat-resistant filler, organic high-temperature-resistant fiber, and polymer emulsion. The preparation method of the coating is to prepare a bottom coating by mixing a heat-resistant binder, a heat-resistant reactive filler, and a heat-insulating filler. The heat-resistant pigment, organic polymer fiber And polymer emulsion to prepare surface coating. The invention is based on an inorganic-organic composite hybrid material as a high-temperature-resistant coating, and adopts a composite coating method to achieve the purpose of heat insulation protection.
Description
technical field [0001] The invention relates to a high-temperature-resistant coating for labor insurance shoe uppers and a preparation method thereof, in particular to a high-temperature-resistant shoe coating and a preparation method thereof. Background technique [0002] Safety protective shoes are a kind of footwear that protect workers from harsh working environments. Early labor insurance shoes were mostly canvas structures, which were dipped or multi-layered to achieve corrosion resistance or high and low temperature working conditions. High-temperature resistant safety protective shoes are mainly used in metal processing workshops such as smelting, foundry and casting processes, and are often damaged by high-temperature metal shavings and metal droplets. Foreign solutions are generally to coat or bond a layer of metal film on the surface of the upper to reflect high-temperature radiation and contact damage, but the manufacturing process is complicated and heavy, and ...
