Abstract
The present invention relates to paint fields, and in particular to a kind of novel aqueous polyurethane coating.It is prepared from the following raw materials in parts by weight：40 48 parts of waterborne polyurethane resin, 23 parts of melamine phosphate, 57 parts of catalyst, 24 parts of foaming agent, 13 parts of plasticizer, 57 parts of coalescents, 25 parts of diatomite, 46 parts of coupling agent, 7 11 parts of diethanol amine, 35 parts of levelling agent.The present invention has strong adhesive force, wearability good, while having many advantages, such as good resistance to dissolubility and water resistance, excellent combination property.
Description
Technical field
The present invention relates to paint fields, and in particular to a kind of novel aqueous polyurethane coating.
Background technology
Polyurethane is mainly used for wall insulation engineering, and polyurethane can be divided into the classes such as spraying and molding by its foam pattern
Type, rigid polyurethane foam is mainly used in construction projects makes various house components and polyurethane sandwich coloured silk steel
Plate plays the effect of heat preservation.It can also directly be sprayed on exterior wall with spray coating method now, form polyurethane external wall thermal-insulation system.
In-situ spraying is now widely used for building level surface thermal-insulating waterproof engineering of integrating, and the integral spray on roofing forms a guarantor
Warm waterproof overall construction, plays the role of thermal-insulating waterproof.In concentrated supply of heating in the city pipeline, it can also be used to do insulating layer.But
The comparison of ingredients of existing polyurethane is complicated, and materials are relatively more, cause cost relatively high, manufacture difficulty is big.
Invention content
The present invention provides a kind of novel aqueous polyurethane coating to overcome existing disadvantages mentioned above.
The technical scheme is that：A kind of novel aqueous polyurethane coating, it is characterised in that：It is by following parts by weight
Raw material be made：40-48 parts of waterborne polyurethane resin, 2-3 parts of melamine phosphate, 5-7 parts of catalyst, 2-4 parts of foaming agent,
1-3 parts of plasticizer, 5-7 parts of coalescents, 2-5 parts of diatomite, 4-6 parts of coupling agent, 7-11 parts of diethanol amine, 3-5 parts of levelling agent.
Further, it is prepared from the following raw materials in parts by weight：45 parts of waterborne polyurethane resin, melamine phosphate
2.5 parts, 5.5 parts of catalyst, 3 parts of foaming agent, 2 parts of plasticizer, 6 parts of coalescents, 4 parts of diatomite, 5 parts of coupling agent, diethanol
9 parts of amine, 4 parts of levelling agent.
Foaming agent of the present invention is that isocyanate reacts the carbon dioxide generated with water.
Plasticizer of the present invention is dioctyl phthalate DOP.
Advantageous effect：Compared with prior art, the present invention it is good with strong adhesive force, wearability, while having good resistance to
The advantages that dissolubility and water resistance, excellent combination property.
