Embodiment Construction

[0020] The present invention will be described in further detail below with reference to specific examples. The following examples are only descriptive and not restrictive, and the protection scope of the present invention cannot be limited by this.

[0021] A flame-retardant urea-formaldehyde resin foamed thermal insulation material, which is made by mixing A component liquid and B component liquid, in which:

[0022] A component liquid:

[0023] It is a mixed liquid of urea and urea-formaldehyde resin aqueous solution. In the mixed liquid, the solid content of the urea-formaldehyde resin aqueous solution is 30-35%, preferably 33%; the weight ratio of urea: urea-formaldehyde resin aqueous solution is 1:14-18, which is the best It is 1:16.

[0024] B component liquid:

[0025] It is a mixture composed of phosphoric acid, non-ionic surfactant, DM flame retardant and water. The weight ratio of each component is:

[0026] Phosphoric acid 3.0~5.0%, best 4%;

[0027] BL-blowing agent 3.0~3.5%...

Abstract

The invention relates to an inflaming retarding type urea resin foam insulation material. The inflaming retarding type urea resin foam insulation material is formed by mixing A-component liquid with B-component liquid, wherein the A-component liquid is mixed liquid of urea and urea resin water solution, the B-component liquid is mixed liquid formed by mixing of phosphoric acid, nonionic surfactant, DM fire retardant and water, and the A-component liquid is mixed with the B-component liquid according to a weight proportion of 1:1 to form the urea resin foam insulation material. According to the inflaming retarding type urea resin foam insulation material, the process is advanced, the formula is scientific, the combustion performance of the inflaming retarding type urea resin foam insulation material is detected according to national standard Classification For Burning Behavior of Building Materials and Products GB8624-2006, the index of the inflaming retarding type urea resin foam insulation material reaches a B level, the burning level of the material is greatly improved, and the continuously improved performance requirements on use of the buildings are met.

Description

Technical field [0001] The invention belongs to the field of building materials, and relates to thermal insulation materials, in particular to a flame-retardant urea-formaldehyde resin foam thermal insulation material. Background technique [0002] Since the urea-formaldehyde resin foam insulation material is a water-based resin, its foaming process uses a physical foaming method, so it will not produce any waste that pollutes the environment during the production process, and has environmental protection performance; moreover, urea-formaldehyde resin Foam insulation materials not only have excellent heat preservation and heat insulation properties, but also have the advantage of low cost, and their development and application prospects are very optimistic. However, the combustion grade of urea-formaldehyde resin foam insulation material is Grade C, which has poor flame retardancy and has certain safety risks. Therefore, it is of great practical significance to develop a urea-fo...
