Description
Technical Field
The invention belongs to the technical field of preparation of fireproof coatings, and particularly relates to a preparation method of a high-temperature-resistant fireproof heat-insulating coating.
Background
The fire-proof paint is a special paint which is used on the surface of flammable base material, can reduce the flammability of the surface of the material to be painted, can retard the rapid spread of fire and is used for improving the fire endurance of the material to be painted.
The existing fireproof coating has the following defects: 1. the fire-resistant heat-insulating property and the high-temperature resistance are not ideal, and the coating after use is easy to crack; 2. in the preparation process, the materials are put into a conventional stirring device for stirring, the stirring performance of the stirring device is poor, the materials are difficult to ensure to be fully mixed, and the problems of material layering and uneven mixing exist; the agitator can't be pulled down, and partial material adhesion is on the inner wall of agitator, and operating space is little, and these residual materials take out inconveniently, influence off-the-shelf collection volume, also be convenient for clear up agitating unit comprehensively.
Disclosure of Invention
The invention aims to solve the technical problems in the prior art, and provides a preparation method of a high-temperature-resistant fireproof heat-insulating coating, which has the advantages of simple process, ordered steps, easy control and adjustment, full and uniform mixing of materials, convenient material taking of a finished product, and excellent high-temperature resistance, fire resistance, heat insulation performance, flame retardance, heat insulation performance and cracking resistance of the prepared coating.
In order to solve the technical problems, the invention adopts the following technical scheme:
a preparation method of a high-temperature-resistant fireproof heat-insulating coating comprises the following steps:
(a) the stirring device is in place: mounting the stirring barrel on the turntable, and fixing the mounting bracket on the mounting table;
(b) stirring and mixing:
firstly, adding silica sol, water, high-temperature-resistant resin, rare earth and mineral fibers into a stirring barrel, starting a driving motor, driving the driving disc to rotate by the driving motor, driving a transmission rod by the driving disc to do eccentric motion, moving a limit pin on the transmission rod back and forth in a limit through groove on a limit rod, driving an arc-shaped mounting rod to swing back and forth by the transmission rod, driving a stirring assembly to stir and mix materials by a fixed rod, wherein the stirring time is 10-12 min, and in the stirring process, flowing materials are in contact with a stirring wheel to drive the stirring wheel to rotate, and the stirring wheel is used for stirring the materials by blades;
secondly, adding titanium dioxide, silica fume and calcium silicate powder into the stirring barrel, and continuously stirring for 5-10 min;
(c) adding an auxiliary agent:
the method includes the steps that auxiliary agents are added into a stirring barrel, a servo motor is started, the servo motor drives a rotary table to rotate clockwise, the rotary table drives the stirring barrel to rotate, materials are stirred and mixed, and stirring time is 5-10 min;
secondly, controlling a servo motor to drive a turntable to rotate anticlockwise, and continuously stirring the materials, wherein the stirring time is 5-10 min;
in the stirring process, the flowing materials continuously collide with the stirring blades to drive the stirring blades to rotate, and the materials are cut and stirred to prepare the coating;
(d) packaging: and (5) detaching the stirring barrel, taking out the coating, packaging and warehousing.
Further, the specific method of the step (a) is as follows: inserting a positioning block at the bottom of a material blocking cover into a positioning slot on the top surface of a stirring barrel to limit the material blocking cover on the stirring barrel; sleeving the sleeve groove on the bottom surface of the block on the L-shaped support rod on the fixing seat on the side surface of the stirring barrel, so that the stirring barrel is limited on the rotary table; thirdly, the rectangular through groove in the positioning plate on one side of the mounting support is sleeved on the rectangular seat on the mounting table, so that the mounting support is limited on the mounting table, the stirring assembly extends into the stirring barrel, then the fastening screw cap is installed on the fixing stud, and the positioning plate is pressed through the fastening screw cap.
Further, the concrete method for detaching the stirring barrel in the step (d) is as follows: unscrewing fastening nut to breaking away from fixed double-screw bolt, upwards lifting up the installing support, detaching the mount table with the installing support, then upwards lifting up the agitator, detaching the carousel with the agitator, the dismouting is simple, and the operation degree of difficulty is low, is convenient for take out the finished product coating in the agitator, and operating space is big, improves the collection volume, reduces extravagantly.
