Currently, room temperature Curing system of vinyl ester Resin has 3 kinds, according to the
China epoxy resin industry association experts introduced: one is ketone peroxide/cobalt
salt promoter, this system can use tertiary amine compounds (mixed) accelerator
acceleration, peroxide ketone compounds of chemical structure of vinyl ester resin curing
has obvious effect.
Some peroxide ketone compounds under the effect of drilling can produce gas in the vinyl
ester resin, so choose to pay attention to, such as peroxide acetylacetone can cause a large
number of bubbles and lead to not curing is not applicable, this system is commonly used in
peroxide ketone compounds are methyl ethyl ketone peroxide, cyclohexanone peroxide, cobalt
salts commonly used cobalt naphthenate, cobalt naphthenate, cobalt and other quantitative;
The second is a proud benzoyl peroxide class this system commonly used benzoyl peroxide, the
second benzoyl peroxide/dimethyl aniline fluid; Three is the peroxide/vanadium promoting
agent/promoter methyl ethyl ketone peroxide recommended or isopropyl benzene hydrogen
peroxide.
When different structural layer is made by resin curing curing system to adjustments, such
as for gel layer of the resin curing system can be used as follows: 100 vinyl ester resin,
methyl ethyl ketone peroxide 2 ~ 3, 2 ~ 3 octylic acid cobalt, diethyl aniline 1. This kind
of curing system in the gel layer and layer resin can be used, so for willing to use a
single curing system of forming the operator is very interested in, this formula the
gelation time of about 15 points (20 ℃), resin gel after 20 ℃ placed 25 points after shop
layer, operation can be performed.
When using the method of hand lay-up or layer by layer injection molding shop, can use the
same formula and the gel layer. With winding room temperature molding shop layer, because
often want to have longer gel time (2 ~ 3 hours), so in the formula can be appropriate to
reduce cobalt salt dosage and without amine compounds, to ensure effectively prolong the
gelation time, considering the thick section on polymerization heat release and winding high
glass fiber content will influence each other curing speed, so appropriate adjustments to
the amount of initiator (slightly lower). This formula can be used in wet winding forming
thicker at room temperature of components and parts, such as pipe and flange of the vessel.
Forming of thin products, if the best results, it must be cured at 100 ℃ for at least 2
hours.
