Belong to salt to be added in tank of sizing mixing together with the solvent of catalyst and remaining part that tertiary amine compounds compound, discharge after dispersion,
Up to base-material；
(2) reaction the preparation of curing agent: is added in aliphatic isocyanates, the pure and mild organometallic salt catalysts of polyether polyols
It in kettle, at the uniform velocity stirs, heats, after insulation reaction, the mass percentage of sample detection isocyano, when the quality of isocyano
It is cooling to get curing agent after percentage composition reaches design value；
(3) preparation of diluent: butyl acetate and high boiling solvent are added in tank of sizing mixing, and are dispersed to get diluent；
(4) preparation of coating: by curing agent obtained by base-material obtained by step (1) and step (2), or it is additionally added step (3) institute
Diluent mixture is obtained, stirs evenly and corrodes wind-driven power generation blade coating to get high resistance to dust storm.
Preferably, in step (1), described pre-dispersed and dispersion mixing speed is 400~800r/min, and the time is
More preferable 50~the 60min of 40~80min().It is difficult if pre-dispersed and dispersion mixing speed is too low since the viscosity of base-material is larger
To achieve the purpose that pre-dispersed and dispersion, if mixing speed is excessively high, material is easy fever, and the volatilization of solvent is more serious, shadow
It rings product quality and will cause environmental pollution.
Preferably, in step (1), the time of the standing is 20~30h.The purpose stood after pre-dispersed is to allow base
Resin in material can preferably soak pigment, be conducive to the dispersion of pigment.
Preferably, in step (1), fineness≤20 μm after the grinding.The purpose of grinding is to allow pigment to divide completely
It is dispersed in base-material, in storage and work progress, will not be precipitated from coating.
In step (1), the purpose that raw material is added separately to is to disperse pigment preferably；The solvent is added in two portions
Purpose be mainly to be conducive to the mixing of raw material, so amount that is pre-dispersed and dispersing be separately added into solvent need not be limited strictly,
But the solvent total amount being added preferably remains unchanged.
Preferably, in step (2), the speed at the uniform velocity stirred is the more preferable 85~100r/ of 80~120r/min(
Min).
Preferably, in step (2), the temperature of the heating is 70~90 DEG C, and the time of insulation reaction is 4~5h.If plus
Hot temperature is too low, and required soaking time greatly extends, and influences production efficiency, if heating temperature is excessively high, it will cause isocyanides
The autohemagglutination of acid esters, influences product quality；What the selection of soaking time was mainly determined according to the completeness of reaction, soaking time
Short, then reaction is incomplete, and soaking time is long, then influences production efficiency.
Preferably, in step (2), the design value of the mass percentage of the isocyano be 5~15%(more preferable 8~
14%).The purpose of sample detection isocyano is to determine the completeness of reaction, to determine reaction end.
Preferably, in step (3), the speed of the dispersion is 200~400r/min, and the time of dispersion is 40~80min.
The viscosity of diluent is very low, if rate of dispersion is too low, can extend jitter time, if rate of dispersion is excessively high, it will cause dilutions
Agent is flowed, its spilling is even resulted in.
Beneficial effects of the present invention are as follows:
(1) the high resistance to dust storm of the present invention corrode wind-driven power generation blade coating can direct spraying in the fan blade table Jing Guo grinding process
Face, for one-pass film-forming thickness up to 210 μm or more, construction efficiency is high；
