Abstract

The invention belongs to the technical field of unsaturated polyester putty, and particularly relates to waterborne two-component unsaturated polyester putty and a preparation method thereof. The waterborne two-component unsaturated polyester putty comprises a component A and a component B, wherein the component A comprises the following constituents: hydroxy acrylic resin, a wetting agent, a coalescing agent, a dispersing agent, an antirust agent, an anti-settling thixotropic agent, a defoaming agent, a drier, a thickening agent, titanium dioxide, talcum powder, heavy calcium carbonate and water; and the component B comprises the following constituents: a curing agent, a water absorbent and silicon dioxide. The waterborne two-component unsaturated polyester putty has the characteristics of low odor and impact resistance, further has high shrinking percentage and good adhesive force, has no harm to constructors, and can be widely applied to fields of furniture, walls, timber doors and automobiles.

Description

technical field [0001] The invention belongs to the technical field of atomic ash, and in particular relates to a water-based two-component atomic ash and a preparation method thereof. Background technique [0002] Atomic ash is commonly known as putty, also known as unsaturated polyester resin putty. crack. Atomic ash can be widely used in filling and repairing of furniture, walls, wooden doors, automobiles and other fields. Today, with the intensification of the global thermal effect, energy conservation and emission reduction is a common problem faced by the world's coatings industry, and water-based coatings are imperative. At present, relevant volatile organic compound (VOC) emission regulations have been issued in various regions of China to restrict the use of oil-based paints. Therefore, it is imperative for putty to be water-based as an auxiliary material for furniture and auto repair. [0003] Traditional putty is composed of unsaturated resin, powder, accelerat...
