Description
Technical field
The present invention relates to a kind of synthetic method of environment-friendly type silane crosslinker, belongs to silane crosslinker synthesis field.
Background technology
Organosilicon sealant mainly has three kinds of de-oxime type, dealcoholized type and de- acetic acid type at present, its sulfidation discharges respectively
Go out oximes, alcohols and acetic acid small-molecule substance.Wherein, oximes small molecule has been considered having potential carcinogenesis, alcohol to human body
Micromolecular particularly methanol, eyesight, respiratory system to human body etc. also have negative effect, the penetrating odor of acetic acid small molecule
Also do not liked for major part construction personnel.Fluid sealant equally also will as one of material indispensable in electronic enterprises
Adapt to the higher and higher technical requirements that industrial chain Downstream Market is proposed.Organosilicon sealant because its excellent high-low temperature resistant,
Ageing-resistant, dielectric properties and low-corrosiveness etc., are applied very generally in electronic enterprises, such as pcb board coating, electronics member device
Part adhering and sealing etc..In use, volatile matter is larger for de-oxime type, and is corrosive to many materials such as copper sheet, for ring
Requirement in terms of guarantor, the organosilicon sealant suitable for electronic enterprises are mainly dealcoholized type.With high-precision electronics industry
Development, common dealcoholized type organosilicon sealant can not meet the market demand, and exploitation novel organosilicon fluid sealant is extremely necessary.
Ethyl lactate has special Rum, fruit and cream fragrance, is a kind of important fine chemical material.Food
Industry is widely used in spices, spices synergist and Wine additive, can be used to allocate food flavor, wine essence and foodstuff flavouring
Fumet, it is also possible to modulate soft drink and inebriant.Simultaneously because ethyl lactate has, nontoxic, dissolubility is good, is not easy to wave
Send out, have the features such as fruity smell, and there is biodegradable, therefore ethyl lactate is great Development volue and application prospect again
" green solvent ".Demulsification acetoacetic ester type fluid sealant is a kind of organosilicon sealant using novel crosslinker, it uses lactic acid
Ethyl ester type crosslinking agent, discharges nontoxic ethyl lactate small molecule in reaction process, harmless, to copper non-corrosiveness, and
Fluid sealant volatile matter is low, superior electrical property, is very suitable for the more demanding high-precision electronics industry of glue.
The content of the invention
It is an object of the present invention to provide a kind of technique is simple, product with stable quality, high income, and to environment without any
Pollution, the synthetic method of the environment-friendly type silane crosslinker of safety and environmental protection.
The technical scheme is that:
A kind of synthetic method of environment-friendly type silane crosslinker, it is characterised in that it includes the following steps:
1), a certain amount of ethyl lactate, three second are put into the reactor with mechanical agitation, constant pressure funnel and condenser
Amine, solvent petroleum ether(60-90 DEG C of boiling range).
2), weigh a certain amount of methyl trichlorosilane and be added in constant pressure funnel, be every point in mechanical agitation speed
Under conditions of 100 ~ 300 turns of clock, controlling reaction temperature starts dropwise reaction, during the dropwise addition of methyl trichlorosilane at 30 ~ 100 DEG C
Between for 3 ~ 6 it is small when, react generation hydrogen chloride gas absorbed by triethylamine after form triethylamine hydrochloride.
3), after reaction, filtered by water vacuum pump pressure, remove the triethylamine hydrochloride in reaction system, with few
The petroleum ether filter cake of amount.
4), mother liquor pass through air-distillation and recycle petroleum ether solvent, the then a small amount of excessive ethyl lactate of vacuum distillation recycling
And a small amount of impurity component is removed, the product of colourless transparent liquid is obtained after filtering.
5), triethylamine hydrochloride neutralized by sodium hydrate aqueous solution, be dry, recycling.Whole process safety, ring
Protect, superior product quality, do not produce a large amount of corrosive hydrogen chloride gas and produce.
Its chemical equation is as follows:
The molar ratio of the methyl trichlorosilane, triethylamine and ethyl lactate is 1:3:3.3.
The solvent petroleum ether quality is three kinds of total matter of reaction raw materials such as methyl trichlorosilane, triethylamine and ethyl lactate
The 50 ~ 100% of amount.
The reaction principle of the present invention:
The present invention is to put into methyl trichlorosilane, triethylamine, ethyl lactate and petroleum ether solvent in reactor by a certain percentage
Reacted, the hydrochloride of reaction generation three ethyl lactate base silane of methyl and triethylamine, wherein petroleum ether solvent was reacting
Effect in journey is to reduce the viscosity of mixture.
After reaction, then system is recycled by air-distillation again first through being filtered under diminished pressure removing triethylamine hydrochloride
Petroleum ether solvent, vacuum distillation obtain product.For triethylamine hydrochloride by neutralizing, after drying process, obtained triethylamine can be with
Absorbent as hydrogen chloride gas again.Whole building-up process, molar yield more than 94.0%, product content reaches 94.0 ~
96.0%, effective content reaches(The sum of main content and effective high-boiling components component content)To 98.0% or so, chloride ion content is less than
5ppm, and material can be recycled fully, non-corrosive hydrogen chloride gas produces, process safety, environmental protection.
The advantages of present invention is compared with existing product is as follows:
(1)The present invention is reacted by methyl trichlorosilane and ethyl lactate first using under the conditions of triethylamine and solvent petroleum ether
Three ethyl lactate base silane crosslinking agent of synthesizing methyl, product are mainly used in organosilicon neutrality fluid sealant, to copper non-corrosiveness,
And fluid sealant volatile matter is low, superior electrical property, is very suitable for the more demanding high-precision electronics industry of glue.
(2)During ketoxime type crosslinking agent use, the diacetylmonoxime chemical substance of release is a kind of potential carcinogenic substance, by
European Union disables in many occasions, limits use scope and potentiality.Ketoxime type crosslinking agent is substituted using ethyl lactate type crosslinking agent,
Nontoxic ethyl lactate small molecule is discharged in reaction process, it is harmless.
(3)Hydrogen chloride absorbs to form triethylamine hydrochloride by triethylamine in the reaction process of the present invention, and precipitation is easy to point
From not producing a large amount of corrosive hydrogen chloride gas, technique is simple, safety and environmental protection.
Three ethyl lactate base silane of methyl provided by the invention, has good cross-linking effect, the demulsification acid second worked it out
Ester type organosilicon sealant has excellent insulation performance, and fluid sealant volatile matter is low, is very suitable for copper metal non-corrosiveness
High high-precision electronics industry is required with glue, existing similar-type products methyl tributanoximo silane can be substituted completely.
