Abstract

The invention relates to single-component high-adhesion quick-drying repair putty which is filling and leveling-up repair putty for defects and damages on surfaces such as various metals and woodware. The single-component high-adhesion quick-drying repair putty comprises the following components: nitrocellulose, toughened resin, adhesion promoting resins, a thixotropic agent, filler, pigment, a plasticizer and a solvent. The single-component high-adhesion quick-drying repair putty disclosed by the invention has the characteristic that mixing is not needed, the repair putty is convenient to use, scraping performance and quick-drying performances are good, and the toughness is good due to the addition of the toughened resin, for example alkyd resin. On adhesion, various adhesion promoting resins are added to bring a synergetic effect of the various adhesion promoting resins into play, so that the adhesion of the single-component putty is greatly strengthened. Meanwhile, the solvent adopts low-smell and low-toxicity propylene glycol monomethyl ether as the solvent, and therefore, the single-component high-adhesion quick-drying repair putty is relatively environment-friendly in comparison with the conventional nitrocellulose putty. The putty disclosed by the invention is used for filling up small scratches for performing small repair, and also can be used for large-area quick repairing.

Description

technical field [0001] The invention relates to a solvent-type nitro putty, in particular to a one-component high-adhesion fast-drying repair putty, which is used for filling and repairing defects and damages on the surfaces of various metals and woodware. Background technique [0002] At present, the putty used for repairing the defect and damage of various metal surfaces and wooden surfaces is divided into two-component and one-component putty. The two-component repair putty is mainly epoxy resin type and unsaturated polyester resin type. Especially the two-component putty based on unsaturated polyester resin (such as: Chinese patent CN101775245B) has the advantages of good scratch coating, fast drying speed and good adhesion. However, the two components need to be mixed when used, which is very inconvenient to use, and the curing time of the mixed two components is short, which is easy to cause waste, and the formula contains highly toxic styrene as a reactive diluen...
