Ceramic fire-resistant functional filling material as well as preparation method and purpose thereof

Abstract

The invention belongs to the technical field of a ceramic organic silicon fire-resistant material, and concretely discloses a ceramic fire-resistant functional filling material as well as a preparation method and a purpose thereof. The filling material is prepared from 80 to 120 parts of ceramic forming powder, 1 to 5 parts of silane coupling agents, 10 to 20 parts of diluting agents, 0.01 to 0.03 part of pH regulators, 2 to 6 parts of ethenyl polysiloxane and 2 to 10 parts of ceramic auxiliary agents. The ceramic forming powder is subjected to surface treatment through the silane coupling agents; grafting reaction is performed with polysiloxane in high-energy rays, so that good compatibility is achieved with organic silicon materials, so that the ceramic conversion rate can be improved. The method is applicable to the preparation of the ceramic fire-resistant material using the organic silicon materials as substrates. The filling material has excellent fire-resistant performance, good processing performance, low cost and convenient and fast production; meanwhile, the dispersion performance of the powder body is excellent; the ceramic forming effects of the prepared material in the flame combustion process is greatly promoted; the formed ceramic body is hard; good fire-resistant and heat-insulation functions are realized.

Description

technical field

[0001] The invention belongs to the technical field of ceramized organic silicon refractory materials, and in particular relates to a ceramized refractory functional filler and its preparation method and application. Background technique

[0002] Ceramic polymer is a new type of fireproof material that has emerged in recent years. It is a composite material made by adding a certain proportion of ceramic filler and flux to the polymer matrix. It can maintain good flexibility of polymer materials at room temperature. , physical and mechanical properties and electrical insulation properties, when encountering an open flame or in a high temperature environment, this composite material can be transformed into a self-supporting ceramic body, thereby preventing the flame from spreading to the inside of the material, insulating the fire and heat, and achieving the purpose of fire prevention . Ceramic polymers have broad application prospects, especially when used as...
