Description
Technical field
The present invention relates to the catalyst fields of unsaturated-resin more particularly to a kind of resin concrete to drain effective unsaturation
Resin catalyst.
Background technique
Resin concrete drainpipe is a kind of Novel drain pipe road, is by materials such as unsaturated-resin, quartz sand, calcium carbonate
A kind of polymer matrix composites being prepared.Has the characteristics that corrosion-resistant, light weight compared with metallic conduit；With concrete duct
It compares, has many advantages, such as that freeze-thaw resistance property is good, intensity is high, short molding cycle, easily carry, install well；With plastic conduit (poly- second
Alkene, polypropylene etc.) it compares, have the characteristics that heat-resist, intensity is high.As a kind of advanced composite material (ACM), resin concrete row
Water pipe is gradually recognized by people, approves, and has used in city, small towns, residence district extensively.
The forming process of resin concrete drainpipe, apparent condition, mechanical property are mainly by the type of unsaturated-resin, anti-
Answer the influence of the factors such as the property of performance and dosage and inorganic fillings.Wherein, the gel time of unsaturated-resin, rear solid
Change the time and mechanical property plays a major role to the quality of resin concrete drainpipe.
According to the specific requirement of resin concrete drainage pipeline production technology, the gel of resin concrete unsaturated-resin
Time is preferably controlled in 7 minutes or so (50g resin, 25 DEG C).If the gel time of resin is lower than 7 minutes, illustrate that resin is anti-
It answers speed fast, is conducive to shorten molding cycle, improves production efficiency.But it will cause reaction system viscosity and rise fastly, to inorganic
The wettability of filler is poor；Product deaerates difficult (bubble generated when unsaturated-resin is mixed with quartz sand), reduces finished product
Mechanical property.On the contrary, the gel time of resin is greater than 7 minutes, resin improves to the wettability of filler, and reaction system is glued
Degree rises slow, easily degassing, product compactness and high mechanical properties.But the production cycle of product length, low efficiency, increased costs.
In addition, the rear curing time of unsaturated-resin is preferably controlled in 2-3 minutes (50g resin, 25 DEG C), especially with
The continuous production processes of continuous casting machine, the length of rear curing time directly affect the platform tricks of the height of production efficiency, mold,
And the aggregate investment of fixed equipment.If the rear curing time of unsaturated-resin is greater than 2-3 minutes, double bond in resin when gel
Conversion ratio it is lower, the mechanical strength of product is inadequate, it is necessary to by product continue to stay in a mold until its intensity meet demoulding want
It asks.If if forced stripper mechanism, easily causing product deformation, collapsing.If the rear curing time of unsaturated-resin is adjusted to be less than 2-3
Minute, the gel time of unsaturated-resin is just very short, and resin easy gel after mixing with aggregates such as quartz sand, calcium carbonate is scrapped,
Very big pressure is brought to processes such as subsequent casting, degassings.
The gel time and rear curing time of unsaturated-resin depend primarily on the molecular structure of resin, catalyst type is used
Amount and environment temperature.The method that molecular structure by adjusting unsaturated-resin changes its gel time and rear curing time, no
Only technical difficulty is big, regulating cycle is long, and the production cost that may cause resin is sharply increased, and production seldom uses in practice
This scheme.Change the gel time of unsaturated-resin and doing for rear curing time by adjusting type and the dosage of catalyst
Method, relatively flexibly, the amplitude of accommodation it is big, be more conform with production actual conditions, be widely adopted in production process.
The difficult point of the prior art is, it is known that catalyst, curing agent type and its catalysis, curing kinetics, insatiable hunger
It is very sensitive to environment temperature with the gel time and rear curing time of resin, there is not suitable catalyst that can set unsaturation
Gel time, rear curing time and production temperature (room temperature) the three's active balance unification of rouge.For example, every liter of production environment temperature
The gel time of high or 10 DEG C of reduction, resin will shorten or extend more than one times.
How the technical problem to be solved by the present invention is to prepare a kind of gel time that can significantly adjust unsaturated-resin
7 minutes or so (50g resin, 25 DEG C), and it is able to maintain that rear curing time is basically unchanged (2-3 minutes), and to production environment
Temperature change is insensitive or the lower catalyst system of sensitivity, can effectively adjust gel time, rear curing time and
With wide spectrum can operating temperature range (15-45 DEG C of room temperature) unsaturated-resin catalyst, and then improve resin concrete draining
The production efficiency of pipe improves the mechanical property of resin concrete drainage pipeline.
