It uses, can be adhered in various substrates；It can also be used simultaneously as a kind of heat stabilizer and chemical stabilizer, so that each component
Substance can be stable reacted in reactor, be not susceptible to side reaction, generate by-product；And (1S, 2S)-(+) -2- benzyl
Oxygroup cyclohexyl isocyanate can be improved 3- isocyanates methylene -3,5, and 5- trimethylcyclohexylisocyanate and 3- are different
Concertedness between cyanic acid ester group propyl trimethoxy silicane, simultaneously participates in reaction；Using dibutyl tin dilaurate as catalysis
Reaction rate is accelerated in agent, shortens the reaction time.It is reacted by the way of being gradually condensed, solvent selects carbonic acid two when reaction
The mixture of methyl esters and ethyl acetate, other components can be evenly dispersed in the mixed of dimethyl carbonate and ethyl acetate in host agent
In bonding solvent, so that being reacted between each component more sufficiently；The pure and mild small molecule polyol of polyether polyols is also added into simultaneously to carry out
Chain extension.
Host agent initial viscosity produced by the present invention is lower, is on the one hand conducive to improve utilization rate of the invention, while can also

It joined curing agent in agent；Curing agent includes levelling agent, foaming agent, butyl titanate, butyl butyrate and dibutylester nylon acids.
As one of new wound point of the invention, by the way that butyl titanate and dibutylester nylon acids are added, in the common work of both substances
Under, good solidification can be played to host agent, greatly improves viscosity of the invention；In addition, the solidification that the present invention uses
Agent has the effect of one " sluggishness ", i.e., curing agent is not strong to the solidification effect of host agent at the beginning, so that viscosity of the invention
A degree of rising is had, but ascensional range is smaller, during this period of time, is handled convenient for worker；Until " lag phase "
After, curing agent can play very strong solidification to host agent, and viscosity of the invention at this time understands substantial increase, finally
Viscosity can meet the needs of actual production life.As another new wound point of the invention, butyl titanate needs to carry out one
Pretreatment, i.e., first butyl titanate and a certain amount of butyl butyrate are mixed, after mixing, then with dibutylester nylon acids into
Row mixing；Rather than directly butyl titanate and dibutylester nylon acids are added in butyl butyrate；The purpose for the arrangement is that protecting
Card butyl titanate and dibutylester nylon acids can be evenly dispersed in butyl butyrate, improve butyl titanate and nylon acid two
The synergistic effect of butyl ester improves solidification effect.
Finally host agent and curing agent are uniformly mixed, obtain high solid low viscosity mirror face synthetic leather inorganic agent of the invention, the conjunction
The solid content of finished leather inorganic agent reaches as high as 80%.And the viscosity at the beginning of the synthetic leather treatment agent is lower, is conducive to worker operation,
The utilization rate of inorganic agent is improved, more economically；After a period of time, viscosity is increased substantially, and can satisfy actual production life needs
It wants.

Cyanate methylene -3,5,5- trimethylcyclohexylisocyanate are commonly called as isophorone diisocyanate, chemical property
Vivaciously, condensation reaction can occur very well, be usually used in preparing adhesive for polyurethane；And 3- isocyanate group propyl trimethoxy silicane
It is a kind of silane with isocyanates, on the one hand can participates in reacting, be used as a kind of crosslinking agent and adhesion promoter, can be glued
It invests in various substrates；It can also be used simultaneously as a kind of heat stabilizer and chemical stabilizer, enable each component substance steady
It is so fixed that be reacted in reactor, it is not susceptible to side reaction, generates by-product；And (1S, 2S)-(+) -2- benzyloxy butylcyclohexyl
Isocyanates can be improved 3- isocyanates methylene -3,5,5- trimethylcyclohexylisocyanate and 3- isocyanate group third
Concertedness between base trimethoxy silane simultaneously participates in reaction；Using dibutyl tin dilaurate as catalyst, accelerate reaction
Rate shortens the reaction time.It is reacted by the way of being gradually condensed, solvent selects dimethyl carbonate and acetic acid second when reaction
The mixture of ester, other components can be evenly dispersed in the in the mixed solvent of dimethyl carbonate and ethyl acetate in host agent, make
It obtains and is reacted between each component more sufficiently；It is also added into the pure and mild small molecule polyol of polyether polyols simultaneously and carries out chain extension.

It joined curing agent in agent；Curing agent includes levelling agent, foaming agent, butyl titanate, butyl butyrate and dibutylester nylon acids.
As one of new wound point of the invention, by the way that butyl titanate and dibutylester nylon acids are added, in the common work of both substances
Under, good solidification can be played to host agent, greatly improves viscosity of the invention；In addition, the solidification that the present invention uses
Agent has the effect of one " sluggishness ", i.e., curing agent is not strong to the solidification effect of host agent at the beginning, so that viscosity of the invention
A degree of rising is had, but ascensional range is smaller, during this period of time, is handled convenient for worker；Until " lag phase "
After, curing agent can play very strong solidification to host agent, and viscosity of the invention at this time understands substantial increase, finally
Viscosity can meet the needs of actual production life.As another new wound point of the invention, butyl titanate needs to carry out one
Pretreatment, i.e., first butyl titanate and a certain amount of butyl butyrate are mixed, after mixing, then with dibutylester nylon acids into
Row mixing；Rather than directly butyl titanate and dibutylester nylon acids are added in butyl butyrate；The purpose for the arrangement is that protecting
Card butyl titanate and dibutylester nylon acids can be evenly dispersed in butyl butyrate, improve butyl titanate and nylon acid two
The synergistic effect of butyl ester improves solidification effect.
Finally host agent and curing agent are uniformly mixed, obtain high solid low viscosity mirror face synthetic leather inorganic agent of the invention, the conjunction
The solid content of finished leather inorganic agent reaches as high as 80%.And the viscosity at the beginning of the synthetic leather treatment agent is lower, is conducive to worker operation,
The utilization rate of inorganic agent is improved, more economically；After a period of time, viscosity is increased substantially, and can satisfy actual production life needs
It wants.
The above is only a preferred embodiment of the present invention, protection scope of the present invention is not limited merely to above-mentioned implementation
Example, all technical solutions belonged under thinking of the present invention all belong to the scope of protection of the present invention.It should be pointed out that for the art
Those of ordinary skill for, several improvements and modifications without departing from the principles of the present invention, these improvements and modifications
It should be regarded as protection scope of the present invention.
