Abstract

The invention discloses aqueous self-spraying automotive chassis nursing and repairing adhesive and a preparation method thereof. The aqueous self-spraying automotive chassis comprises a film forming matter and a propellant, wherein the film forming matter is obtained by adding 55%-70% by weight of aqueous resin into a stirring cylinder, then, adding 5%-10% of water, starting the stirrer until the aqueous resin is uniformly dissolved, respectively and slowing adding 3%-5% of auxiliaries for stirring until uniformly mixing, adding 1%-10% of pigment and 5%-30% of filler, adding a thickener under a medium-speed stirring condition while dispersion fineness is needed to be less than 15 mu m, and uniformly mixing, so that viscosity is needed to reach 10000mPas / 20; the propellant is obtained by filling enough propellant, wherein the film forming matter to the propellant in percent by weight is 3:2, and forming a rubber film protective layer by compressed air or mechanical pressure. The aqueous self-spraying automotive chassis nursing and repairing adhesive disclosed by the invention realizes aqueous self-spraying function, has a good metal rust-proof function and has excellent storage stability.

Description

technical field [0001] The invention relates to the field of car chassis care, in particular to a water-based self-spray car chassis care repair glue and a manufacturing method thereof. Background technique [0002] Car chassis care glue is a coating for car chassis to prevent rust and reduce noise from the chassis. Generally, before the new car is delivered to the owner, it is a product that is constructed at the sales shop. According to the classification of solvents, there are two types of water-based products and oil-based products; according to the construction method, it is divided into two types: mechanical construction and self-spraying. The technology of water-based chassis glue and oil-based chassis glue for mechanical construction is basically mature; the self-spraying type belongs to the repair type, and the technology of oil-based self-spraying chassis care repair glue is mature and has undergone many technical updates; , Toxic and pungent-smelling solvents, w...
