Problems solved by technology

[0003] 1) Use aromatic hydrocarbon solvents such as toluene and xylene, which are toxic, and will cause harm to the human body if they are accidentally touched or inhaled by on-site workers;
[0004] 2) It adopts two-component form, the drying speed is slow, often more than 10 minutes, and it needs to be cured. At the same time, because it is a two-component form, it must be mixed before use, which is inconvenient to operate

Embodiment 1

[0028] Prepare the raw materials according to the following components and weight percentages:

[0029]

[0030]

[0031] Add the elastic resin and methyl ethyl ketone to the mixer and stir for 2 hours, control the rotation speed to 1440 rpm, so that the elastic resin is completely dissolved in the methyl ethyl ketone; at a stirring speed of 800 rpm, gradually add the elastic powder and the sub Light powder, anti-yellowing additives and wetting and dispersing additives; stir for another 10 minutes, control the speed to 1440 rpm, so that the raw material components are evenly dispersed, and it is ready;

[0032] After testing, the solid content is 33%, the viscosity measured by the immersion type No. 4 viscosity cup is 35 seconds, and the meter is dry for 20 seconds.

Abstract

The invention discloses an elastic pencil oil paint which comprises the following components in percentage by weight: 12.5% of elastic resin, 64% of butanone, 20% of elastic powder, 1.5% of matt powder, 1% of an anti-yellow assistant and 1% of a wetting dispersing auxiliary. The invention further provides a preparation method of the elastic pencil oil paint. The elastic pencil oil paint disclosed by the invention is free from aromatic hydrocarbon solvents, non-toxic and environment-friendly and does not cause damage to bodies of field workers. The elastic pencil oil paint in a form of a single component needs not to be solidified, and only 20 seconds are needed for surface dry, so that the drying speed is greatly improved. The oil paint is simple and convenient to operate and just can be used after being uniformly stirred in a stirrer.

Description

Technical field [0001] The invention relates to a pencil paint and a preparation method thereof, in particular to an elastic pencil paint and a preparation method thereof. Background technique [0002] At present, similar products of elastic pencil paint on the market have the following defects: [0003] 1) Use aromatic hydrocarbon solvents such as toluene, xylene, etc., and aromatic hydrocarbon solvents are toxic, and if accidentally touched or inhaled, it will cause harm to the human body; [0004] 2) It adopts two-component form, the drying speed is slow, often more than 10 minutes, and it also needs to be cured. At the same time, because it is a two-component form, it must be mixed before use, which is inconvenient to operate. Summary of the invention [0005] The purpose of the present invention is to provide an environmentally friendly and fast drying elastic pencil paint in order to solve the above problems. [0006] Another object of the present invention is to provide a metho...
