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
The invention belongs to building materials field, relate to lagging material, especially a kind of flame retardant type urea-formaldehyde resin foaming thermal insulation material.
Background technology
Urea-formaldehyde resin foaming thermal insulation material is owing to be water-based resin, and what its foam process adopted is again physical foaming method, therefore can not produce any waste to environment in making processes, has environmental-protecting performance; And urea-formaldehyde resin foaming thermal insulation material has again cheap advantage when having excellent insulation, heat-proof quality, and its development and application prospect is very optimistic.But the burning grade of urea-formaldehyde resin foaming thermal insulation material is the C level, and flame retardant properties is relatively poor, has certain potential safety hazard.Therefore, develop the urea-formaldehyde resin lagging material that combustionproperty reaches the B level, be of great practical significance.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, the flame retardant type urea-formaldehyde resin foaming thermal insulation material that provides a kind of combustionproperty to reach the B level.
The present invention realizes that the technical scheme of its purpose is:
A kind of flame retardant type urea-formaldehyde resin foaming thermal insulation material is mixed by A component fluids and B component fluids, wherein:
The A component fluids is the mixed solution of urea and urea-formaldehyde resin aqueous solution;
The B component fluids is that phosphoric acid, nonionogenic tenside, DM fire retardant and water mix the mixed solution that consists of;
A component fluids and B component fluids by weight proportion 1:1 are mixed, and namely consist of urea-formaldehyde resin foaming thermal insulation material.
And the urea of formation A component fluids: the part by weight of urea-formaldehyde resin aqueous solution is 1: 14～18.
And the solids content of described urea-formaldehyde resin aqueous solution is 30～35%.
And each the composition weight ratio that consists of the B component fluids is:
Phosphoric acid 3.0～5.0%;
BL-whipping agent 3.0～3.5%;
DM fire retardant 18%～25%;
Water surplus.
Advantage of the present invention and beneficial effect:
1, technique of the present invention is advanced, and scientific formulation can be controlled at any harmful substance contents such as formaldehyde in the relevant national standard scope, reaches nuisanceless green environmentfriendly products standard.
2, the invention belongs to efficient lagging material, its thermal conductivity≤0.034W/ (mk), can farthest improve the thermal and insulating performance of building envelope, its performance index have have also met or exceeded same kind of products at abroad, and environmental protection, with low cost, price only is 60～75% of imported product, having very large development space and application prospect, is the regeneration product of existing all kinds of foaming thermal-insulatings.
3, combustionproperty of the present invention by GB " material of construction and goods classification system for fire performance GB8624-2006 detect, and its index reaches the B level,, greatly improved the burning grade of material, satisfy building and use the performance requriements that improves constantly.
Embodiment
The invention will be further described below in conjunction with specific embodiment, and following examples are descriptive, is not determinate, can not limit protection scope of the present invention with this.
A kind of flame retardant type urea-formaldehyde resin foaming thermal insulation material is mixed by A component fluids and B component fluids, wherein:
The A component fluids:
Be the mixed solution of urea and urea-formaldehyde resin aqueous solution, in this mixed solution, the solids content of urea-formaldehyde resin aqueous solution is 30～35%, and the best is 33%; Urea: the part by weight of urea-formaldehyde resin aqueous solution is 1: 14～18, and the best is 1:16.
The B component fluids:
For phosphoric acid, nonionogenic tenside, DM fire retardant and water mix the mixed solution that consists of, each composition weight ratio is:
Phosphoric acid 3.0～5.0%, the best are 4%;
BL-whipping agent 3.0～3.5%, the best are 3.4%;
DM fire retardant 18%～25%, the best are 22%;
Water the best is 70.6%.
It is the finished product of cost lagging material that above-mentioned A, B Two-component liquid mix in 1: 1 ratio.A, B Two-component liquid will separately be preserved when preserving; In use, A, B Two-component liquid are mixed in the foaming machine spray gun and directly be filled in basic unit's member or the cavity, this mixed aqueous object namely was solidified to form rapidly in 1 minute has micropore, continuous, as to be generally white foams, reaches the heat insulating requirement of buildings.
By test, the combustionproperty of this lagging material reaches the B level.
