Description

Continuous dewatering mixed pouring device and process for high-viscosity filler-containing heat-insulating coating

Technical Field

The invention belongs to the field of heat-insulating coating layers, relates to the field of heat-insulating coating layers with high viscosity and high solid content, and particularly relates to a continuous dewatering and mixed pouring device and process for a heat-insulating coating layer with high viscosity and filler.

Background

A common application area for high solids content and high viscosity insulating coatings is that of propellant products. The heat-insulating coating material contains solid-phase components such as organic filler, carbon fiber material and the like, and the solid-phase content is generally 10% -60%. The high solid-phase filler enables the viscosity of the heat-insulating coating layer to be extremely high and the fluidity to be extremely poor, the production mode at the present stage is mainly full manual operation, firstly, the adhesive and the solid-phase filler are mixed into a component A by adopting a kneading machine and a three-roll calender; when the catalyst is used, the component A and the component B are respectively placed in a heated vacuum box for vacuumizing for about 30min, then the component A and the component B are poured into a container according to the proportion, and simultaneously the catalyst is added and stirred by a manual hand-held stirring rod for about 1 min. Stirring is increasingly difficult because, after the addition of the catalyst, the component A and the component B undergo a curing reaction. And in the stirring process, the mixture is directly contacted with the air, so that the moisture in the air is brought into the mixture, the moisture in the air and the component A react to generate carbon dioxide, and the carbon dioxide gas generates pores in the mixture, so that the product contains pores and the quality of the product is influenced.

After stirring is finished, pouring the stirred mixture into a mold manually, wherein the stirring time is long, so that the reaction time of the component A and the component B is long, the viscosity is increased, and the pouring is difficult; the process bubbles wrapped in the mixture in the casting process can not smoothly overflow.

Based on the characteristics of the high-solid-content and high-viscosity heat-insulation coating material, the processing technology mainly has the advantages of long process period, more process links and low product yield caused by bubbles generated in the process; in summer weather with high humidity, the product yield is even less than 60%.

C. intermittent continuous mixed casting: setting the pouring time T and pouring interval time Delta T of a single product through calculating the material density; the control program of opening and closing the third electromagnetic valve I and the third electromagnetic valve II and the rotation and stop of the continuous mixing head is the same as the step B; the time from the opening to the closing of the third electromagnetic valve I and the third electromagnetic valve II is T; the time from the closing to the opening of the third electromagnetic valve I and the third electromagnetic valve II is delta T;

in the step A:

the component A is in a viscous state containing solid phase filler, the mass percentage of the solid phase filler is 20-80%, and the viscosity is 10-200Pa.s;

the component B is single-component liquid, and the viscosity is 2-20Pa.s;

the mass ratio of the component A to the component B is (1-3) to 1;

the catalyst accounts for 0.05-0.2% of the total mass of the component A and the component B;

in the step A:

vacuumizing to the vacuum degree of-85 kPa to-100 kPa;

the rotating speeds of the stirring paddle I and the stirring paddle II are respectively 10-40rpm and 10-100rpm;

the temperature in the jacket I and the jacket II is 50-75 ℃ and 40-60 ℃ respectively;

the flow rates of the component A metering pump and the component B metering pump are both 0.5L/min to 5L/min;

in the step B, the pressure of the pressure regulating valve I and the pressure regulating valve I are 100kPa-120kPa; setting the pouring speed to be 0.5L-10L/min; the rotating speed of the continuous mixing head is 1000-3000rpm.
