Abstract

An environment-friendly aqueous putty consists of main putty and an initiator. The putty is obtained by evenly mixing the main putty and the initiator at required weight ratio. The main putty consists of the following components: an air-drying water-born unsaturated polyester resin, deionized water, an anti-shrinking agent, a promoter, a wetting dispersant, an anti-skinning agent, an anti-settling agent, an adhesion promoter, an anti-mildew agent, a structure reinforcing agent and packing. The initiator consists of the following components: benzoyl peroxide, dibutyl phthalate and silicon dioxide. The putty has the advantages that air-drying performance of a product is hardly affected by temperature of construction environment; the product has high environmental protection performance, good service performance in construction, special structure reinforcing agent and high overcoatability for use.

Description

Technical field: [0001] The invention relates to an air-drying water-based unsaturated polyester resin putty, which is an environment-friendly water-based putty. technical background: [0002] Putty is a kind of polymerized putty with unsaturated polyester resin as the main body, the trade name or commonly known as putty. It is mainly used for caulking and filling of metal and non-metal before painting, so as to make the substrate smooth and smooth before painting, and to facilitate painting construction. The use of atomic ash involves high-end automobile production and repair, decoration and decoration, furniture production and manufacturing, hardware and metal product production and manufacturing and other industries. Modern requirements for material surface decoration are getting higher and higher. The utilization rate of atomic ash, which is one of the main supplies for substrate treatment, is increasing; the amount of use is also increasing. In the case of increasing...
