Multifunctional facing coating of wood fireproof door

Abstract

The invention discloses a multifunctional facing coating of a wood fireproof door, comprising the following components in percentage by weight: 25.5-37wt% of white latex, 45-60wt% of cornstarch, 12-15wt% of gray soil material and 2.5-3wt% of white cement, wherein the solid content of white latex is 452%, the lowest film forming temperature is more than or equal to 5 DEG C, the viscosity is 3000-50000 mpa, and s is less than or equal to 25 DEG C; the granularity of the cornstarch is 450-800 meshes; the granularity of the gray soil powder is 450-800 meshes; and the mark of the white cement is 325-425. In the multifunctional facing coating, paste mixed by a large dose of white latex and superfine ingredients is fine and moist, has strong adhesive force after being coated, has a strong facing coating and has small possibility of cracking after being knocked, thus the facing coating is fireproof, waterproof, antisepticise and anti-cracking. The multifunctional facing coating can be applied both in border hard materials, but also in board coating.

Description

technical field [0001] The invention relates to a wooden fireproof door finish coating, in particular, the invention relates to a wooden fireproof door finish coating with fireproof, waterproof, anticorrosion and anti-crack functions. Background technique [0002] Fire doors are necessary safety equipment for modern buildings. Their fire performance mainly depends on their fireproof structure and materials. The fireproof measures include door cores with built-in flame retardant materials, preservatives, external fireproof panels and fireproof paints. Layer, the structure and the materials used have strong flame retardancy and anti-corrosion properties, meeting the requirements of building fire protection regulations. However, the coating structure of the prior art has poor density and weak adhesion, and is easy to crack after impact, especially the coating will peel off due to moisture after impact. Damage to the fireproof finish coating of wooden fire doors will inevitably...

AI Technical Summary

Problems solved by technology

However, the coating structure of the prior art has poor density, weak adhesion, and is easy to crack after impact, especially the coating will peel off after being affected by moisture.

Damage to the fireproof finish coating of wooden fire doors will inevitably reduce the fireproof performance, lose the proper fireproof effect, and constitute a safety hazard
