Abstract

The invention discloses a spraying type putty, which comprises main ash and a curing agent. The main ash includes the following components in parts by weight: 35-40 parts of highly elastic unsaturated polyester resin, 15-20 parts of air-drying unsaturated polyester resin, 3.0-5.0 parts of cobalt isooctanoate , 0.2-0.3 parts of dimethylaniline, 2.0-2.5 parts of wetting and dispersing agent, 2-3 parts of titanium dioxide, 8-10 parts of organic bentonite, 1.5-3.0 parts of fumed silica, 15 parts of talc powder Servings to 23 servings. In the present invention, the main ash is changed from viscous pasty body to semi-liquid flowable body, and a liquid solidifying agent is used. After the two are mixed, they are still liquid, and the method of spraying is used for construction. Compared with conventional paste scraping, spraying atomic ash can quickly flatten defect parts, and is less prone to sand holes, significantly improving construction efficiency and greatly saving man-hours; at the same time, the spraying method reduces the difficulty of operation and reduces the need for The dependence on the technical level of construction workers ensures the quality of the coating film.

Description

technical field [0001] The invention relates to a spray-coated putty and a preparation method thereof, belonging to the technical field of embedded filling materials. Background technique [0002] Atomic ash, commonly known as putty, is composed of main ash and curing agent. It is a new type of embedding material that is convenient and quick to use. It can be well attached to the surface of the material and quickly formed. It is widely used in train manufacturing, ship manufacturing, automobile manufacturing, etc. Various fields of metal products that need to be filled and repaired, effectively fill and modify defects such as substrate pits, pin shrinkage cavities, cracks, welds, etc., to meet the leveling and smoothness of the substrate surface before topcoating. [0003] At present, the construction of atomic ash is all by scraping, which requires high skills for the scraping construction personnel, and the main ash must be mixed with a paste-like curing agent before use. ...
