Abstract
The invention discloses a pouring-type modified urea resin foaming thermal-insulation material. The pouring-type modified urea resin foaming thermal-insulation material is composed of a group A of materials and a group B of materials, the group B of materials comprises phosphoric acid, foaming agents, foam stabilizers and water, sodium dodecyl sulfate is selected to be the foaming agents, silicon resin polyether emulsion is selected to be the foam stabilizers, the group A of materials comprises a urea resin water solution and cross-linking agents, and polyhydric alcohol is selected to be the cross-linking agents. In the using process, the group A of materials and the group B of materials are mixed to be foamed so as to obtain the thermal-insulation material, foaming speed is high, and the obtained thermal-insulation material is good in thermal-insulation effect, high in tenacity, not likely to crack and capable of meeting requirements for thermal-insulation materials in building industry construction due to non-pulverization.
Description
Technical field
The invention belongs to building trade lagging material technical field used, be specifically related to a kind of casting type modified urea-formaldehyde resin foaming thermal-insulating.
Background technology
The foaming thermal-insulating used in building trade has the material of foaming in advance, also has casting type material, and casting type material needs fast pouring shaping at the construction field (site).
Urea-formaldehyde resin foaming thermal insulation material is a class lagging material conventional at present, owing to belonging to water base property resin, physical foaming method is adopted during use, therefore environmental protection, urea-formaldehyde resin class foaming thermal-insulating has excellent insulation, heat-proof quality in addition, and cheap, therefore apply very extensive.
But existing urea-formaldehyde resin foaming thermal insulation material expansion rate is slow, and cast-in-site toughness is poor, easily cracking and efflorescence, therefore still needs to improve.
Summary of the invention
