Description
Technical field
The invention belongs to chemical coating fields, and in particular to a kind of dual cure urethane acrylate of chemical resistance；
In addition, the preparation method of the dual cure urethane acrylate the invention further relates to the chemical resistance.
Background technology
Ultraviolet light（UV）Curing technology is since it is with curing rate is fast, curing membrane performance is excellent, solvent-free using process
Release, low in the pollution of the environment, solidification process energy expenditure is low, can automated production, the advantages that being suitable for use on heat-sensitive substrate material, and
It obtains widely studying and applying.
UV coating material solidified is a kind of environmental type coating, has many advantages, such as that low energy consumption, volatile matter is few, hardening time is short.
UV is coating material solidified to be mainly made of prepolymer, activated monomer, photoinitiator and auxiliary agent, and wherein prepolymer constitutes cured film friendship
Join the skeleton of reticular structure, it is the main determining factor of product physical and chemical performance.Using aliphatic made from IPDI, HDI
UV cures prepolymer has the advantages that color inhibition compared with aromatic series UV cures prepolymer, and assigns the better toughness of film.Water
UV is coating material solidified can very easily adjust coating thickness for property, and taste is small, is more suitable for meeting the needs of modern society.
Coating is a kind of containing pigment or without pigment, the chemical products made of resin and oil etc..Coating is coated in
It dry and hard can forming a film on body surface, the surface and surrounding medium for making coated article body are isolated, so as to be played to coated article body
Protection and the effect of decoration.According to function difference, coating includes：Decorative paint, anticorrosive paint, insulating moulding coating and fireproof coating
Deng.In recent years, with continuous enhancing of the people to environmental protection consciousness, own health is constantly paid close attention to, there is an urgent need to one kind both
Environmentally friendly low-carbon, but to construction personnel itself without the coating of too big murder by poisoning, thus UV coating is also just born, and quickly sent out
Exhibition.
Existing UV coating is typically all simple photocuring reaction, that is, passes through the irradiation of ultraviolet light so that photoinitiator
Free radical is decomposited, these free radicals generate cross-linking reaction by UV resins, obtain cured paint film.According to the mode used not
Together, it is divided into as roller coating UV coating, showering UV coating, brushing UV coating, spraying UV coating etc..Roller coating UV coating exists in itself
Have preferable adhesive force above timber, bamboo wood and part high molecular polymer, but for metal material, the power that just seems not from
The heart, face easily comes off the paint film after curing on the metal material, leads to not face on the metal material and uses UV coating and UV
For coating in itself without what chemicals-resistant corrosive nature, mechanical flexibility is very poor.
Therefore, it is necessary to a kind of environmental protection, solvent-free volatilization, rapid curing, and can have preferable attachment in face on the metal material
Power has preferable flexibility, acidproof, alkaline-resisting, water resistance coating.
