Abstract
The invention relates to a composite reinforced self-adhesive mica tape and a preparation method thereof, belonging to the technical field of insulating products. The composite reinforced mica tape is prepared by mixing the reinforced fibers directly in the preparation process, other reinforcing layers are not required to be added, and meanwhile, an adhesive is coated on one surface of the mica tape before winding, so that the mica tape can be directly fixed in use without other auxiliary measures, and the sizing is convenient.
Description
Technical Field
The invention belongs to the technical field of insulating products, and particularly relates to a composite reinforced self-adhesive mica tape and a preparation method thereof.
Background
Mica tape is the most critical insulating material in the field of motors and can hardly be replaced. However, mica is brittle, and is easy to crack when other auxiliary materials are added. Therefore, in the production process of the traditional mica tape, the outside of the mica tape is coated with a binder to bond other reinforcing materials. Therefore, the mechanical property of the mica tape can be improved, but the insulation thickness of the mica tape is increased, the mica content is reduced, and the problem of practical use is brought.
Disclosure of Invention
The purpose of the invention is as follows: aiming at the defects of the existing insulating material, a composite reinforced self-adhesive mica tape and a preparation method thereof are provided.
The technical scheme adopted by the invention for solving the technical problems is as follows: a composite reinforced self-adhesive mica tape and a preparation method thereof comprise the following components: mica, reinforcing fibers and adhesive.
The reinforcing fiber is one of glass fiber, aramid fiber and polyester fiber, and the fiber length is 200-500 mm.
The adhesive is an acrylate pressure sensitive adhesive.
A preparation method of a composite reinforced self-adhesive mica tape comprises the following steps:
the method comprises the following steps: and (3) placing the mica sheets in a calcining furnace for calcining at the temperature of 900-980 ℃ for 20-30min, and after cooling, sieving by using a 10-mesh sieve to obtain the mica clinker.
Step two: and (3) placing the mica clinker in an acid solution for soaking for 20-30min, then placing the mica clinker in a reaction kettle, and heating to prepare mica cooked slurry.
Step three: adding reinforcing fiber into the mica cooked slurry, wherein the adding amount is 5-15% of the mass of the slurry, stirring uniformly, then making the mica paper by using a net, and drying to obtain the mica paper.
Step four: cutting the mica paper into strips according to actual requirements, and coating an adhesive on one surface of the mica paper to prepare the composite reinforced self-adhesive mica tape.
The invention has the beneficial effects that: the reinforcing fiber is added when the mica tape is in a slurry stage, so that the mica tape can be sufficiently reinforced after being sliced, a reinforcing material is not required to be added outside, and the thickness of the mica tape is reduced. One side of the mica tape is coated with the adhesive, so that the mica tape can be directly shaped in the using process, the mica tape shaping device is convenient to use, the subsequent shaping procedures are reduced, and the labor intensity is reduced.
Detailed Description
The present invention is further illustrated by the following specific examples.
Examples
A composite reinforced self-adhesive mica tape comprises the following components: mica, reinforcing fibers and adhesive.
The reinforcing fiber is one of glass fiber, aramid fiber and polyester fiber, the fiber length is 200-500mm, and longer fibers can achieve better reinforcing effect in the sheet material. The adhesive is an acrylate pressure-sensitive adhesive, and the pressure-sensitive adhesive has no viscosity when not receiving external pressure, so that the adhesive is convenient to shape in the installation process, and the labor intensity of subsequent shaping is reduced.
The manufacturing method of the composite reinforced self-adhesive mica tape comprises the following steps: firstly, placing mica sheets in a calcining furnace for calcining at the temperature of 900-. And (3) placing the mica clinker in an acid solution for soaking for 20-30min, then placing the mica clinker in a reaction kettle, and heating to prepare mica cooked slurry. Adding reinforcing fiber into the mica cooked slurry, wherein the adding amount is 5-15% of the mass of the slurry, stirring uniformly, then making the mica paper by using a net, and drying to obtain the mica paper. Cutting the mica paper into strips according to actual requirements, and coating an adhesive on one surface of the mica paper to prepare the composite reinforced self-adhesive mica tape.
The composite reinforced self-adhesive mica tape prepared by the invention improves the mechanical property of the mica tape, makes the mica tape tougher without coating a reinforcing material outside, reduces the insulation thickness of the mica tape when in use, and is more convenient and flexible when in use. One side of the mica tape is coated with the pressure-sensitive adhesive, and the mica tape can be directly shaped according to the shape of the component during actual installation, so that the subsequent shaping procedures are reduced, and the labor intensity is reduced.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
