[0069] Put the weighed components into the sand mill, but only 1 / 3 of the cellulose fibers. Close the lid, tighten the screws, and stir for 30 minutes to fully dissolve the components in the solvent, then start the machine for sanding. Add 1 / 3 of the cellulose fibers after 2 hours of sanding, and add the final 1 / 3 of the cellulose fibers after 4 hours of sanding. After sanding for 24 hours, take regular samples to check the average particle size. When the average particle size is 90 microns, stop sanding and discharge.

Abstract

The invention relates to a fire-resisting paint and its use, wherein the fireproofing coating composition comprises composite film forming resin 15-30 wt. portions, expansion combustion inhibitor 27-40 wt. portions, flame-proof insulating material 2-15 wt. portions, fabric filling material 1-5 wt. portions, coating material solvent 30-45 wt. portions, wherein the particle mean size of the solid state components is 1-90 micrometer. The fireproofing paint can be applied to cable coating which can substantially extend the fire-resistant period for the cable.

Description

technical field [0001] The invention relates to a fireproof coating and its application. The fireproof coating can be used as the outer coating of cables and wires, so that the cables can keep electricity safely for a certain period of time in a fire. Background technique [0002] Wires and cables are prone to fire and have great fire hazards. Therefore, cable fire protection is an important research topic in the field of fire protection. At present, fire-resistant cables, flame-retardant cables, and cable fire-resistant coatings have been developed at home and abroad. Among them, brushing the cable fireproof coating on the surface of the cable can effectively reduce the occurrence of fire and prevent the spread and spread of the flame. It is a simple and economical means. In GA181-1998), the detection of flame retardancy and fire resistance is only one item of carbonization height, so there are few domestic reports on the fire resistance of cables coated with cable fire re...
