Preparation method of epoxy coiled material joint mixture

Abstract

The invention discloses a preparation method of an epoxy coiled material joint mixture, which comprises the following specific steps: ensuring that the interior of an original stirring device main body is dry, introducing powder into the stirring device through a first feed port according to a proportioning ratio, and controlling a main motor to uniformly rotate, thereby obtaining uniformly premixed powder; weighing a certain amount of liquid materials according to the formula, adding the liquid materials into the stirring device, and evenly stirring the internal raw materials by controlling the ratio of the powder to the liquid. A rotating speed sensor detects the change of the rotating speed of a stirring rod and transmits a signal to a central processor, then the central processor controls a current control module to work, and current signals, current feedback signals and the like are conveniently integrated through the multiple input ends; the rotating speed of the main stirring blades and the arc-shaped stirring blades in the stirring device main body is increased, and the first stirring blades and the second stirring blades begin to rotate, so that internal stirring is not influenced by consistency, and uniform mixing of raw materials is better realized.

Description

technical field [0001] The invention relates to the field of caulking agents, in particular to a method for preparing epoxy coil caulking agents. Background technique [0002] Acid and alkali-resistant epoxy coiled material is a new type of floor material in the flooring industry. It is based on an elastomer-toughened epoxy resin and polyurethane compound resin system, reinforced by glass fiber, and prepared by a special curing process. materials, in the process of paving and construction, the gap between adjacent coils needs to be filled with caulking agent. With the improvement of people's living standards and awareness, the coiled material caulking agent has also developed from the initial white cement to The current mainstream polymer coil sealant.

Problems solved by technology

[0003] The existing joint fillers need to be stirred during the production process. However, there is no absolute standard for judging the degree of uniformity of mixing. The existing stirring devices cannot meet the stirring requirements during the production of joint sealants. During the stirring process, because there are too many variable factors, the compressive and flexural strength of the caulking agent are seriously affected, including the ratio of powder to liquid, the mass ratio of epoxy resin emulsion to epoxy resin curing agent, etc.;

[0004] Among them, the ratio of powder to liquid material plays a key role, which is the key to the synthesis of caulking agent. Too much powder will affect the stirring due to too much consistency, which will further affect the synthesis of finished caulking agent; also, epoxy resin When the mass ratio of the emulsion to the epoxy resin curing agent is greater than or equal to 1.80, the consistency of the caulking agent is the largest and it is difficult to stir. The existing stirring device cannot control the stirring speed at the moment when the consistency is just reached. It will cause the mixing device to stir hard and damage the motor. The traditional stirring can only complete the stirring at a uniform speed, and cannot better achieve uniform mixing. The quality of the synthetic caulking agent is not good, which seriously affects the compressive and flexural strength of the caulking agent. , for this reason, we propose a preparation method of epoxy coil sealant
