Abstract
The invention discloses aqueous sealant and a preparation method thereof. The aqueous sealant comprises the following components in percentage by mass: 40 to 50 percent of aqueous resin emulsion, 10 to 15 percent of ethanol, 10 to 15 percent of glass fiber powder, 5 to 10 percent of glass powder, 10 to 15 percent of inorganic bonding agent, 10 to 20 percent of inorganic adhesion promoter and 0.5 to 1 percent of dispersing agent. Prepared from aqueous resin, the aqueous sealant does not pollute environment and is environment-friendly. Simultaneously, a certain quantity of ground glass fibers are added into the sealant, so that the physicochemical properties of the sealant can be improved obviously, the bonding performance is high, and the bonding is firm; and a coating is high in hardness, crack resistance, abrasive resistance and the like, and the stability of a resin bonding agent also can be improved.
Description
Technical field
The invention belongs to electric elements seal gum technical field, relate to a kind of aqueous sealant and preparation method thereof.
Background technology
Seal gum is a kind ofly to be out of shape with the trim shape, is difficult for trickling, and certain close-burning sealing material is arranged, and is to be used for filling the configuration gap to play the tackiness agent of sealing function, can rely on drying, temperature variation, solvent evaporates, progressively curing molding.In order to guarantee the reliable and stable of motor, electric elements electrical property and physical strength, need be between the conductor, use seal gum to seal between slit and outlet lead-in wire.Be widely used in being used for the bonding reinforcing of the adhering and sealing and the electronic component of class household electrical appliance.
Along with the reinforcement of environmental consciousness, the requirement of aqueous sealant has been proposed.This is because the aqueous, environmental protective formula system of aqueous sealant has guaranteed ultralow VOC quantity discharged.Safety and environmental protection, the volatilization of organic solvent-free in the use, all unharmful substance produces, and has guaranteed the environmental-protecting performance of product.
Meanwhile, along with the development of electronic enterprises, need that adhesive property is better, bonding is more firm; The seal gum that coating hardness is bigger, splitting resistance is better, wear resistance is stronger etc.
Summary of the invention
The problem that the present invention solves is to provide a kind of aqueous sealant and preparation method thereof, is the environment-friendly type seal gum, and bonding firmly can be applicable to the bonding reinforcing of the adhering and sealing and the electronic component of household electrical appliance.
The present invention is achieved through the following technical solutions:
A kind of aqueous sealant, in massfraction, comprise 40～50% resin aqueous emulsion, 10～15% ethanol, 10～15% glass fiber powder, 5～10% glass powder, 10～15% mineral binder bond, 10～20% inorganic short stick and 0.5～1% dispersion agent;
Described mineral binder bond is aluminum oxide or kaolin, and its size is 0.2～10 μ m;
