Abstract

The invention provides a blueprint paper, which comprises a paper base, one side of the paper base is covered with a top coat, and the raw material of the top coat includes fluorine-containing thermosensitive microcapsules. The present invention also provides a preparation method for the above-mentioned blueprint paper. The blueprint paper prepared by the present invention adopts fluorine-containing heat-sensitive microcapsules for color development, enhances its waterproof, light-resistant, and heat-resistant properties, and at the same time can make its exposure area have a higher image density, so that it can meet the requirements of the blueprint paper on Accuracy issues in engineering drawing. The blueprint paper prepared by the present invention has no raw materials and preparation process that can irritate the human body and the environment. No matter whether the blueprint paper is prepared or used, the staff will not have health problems because of it, and at the same time, it is friendly to the environment. Suitable for mass production use.

Description

technical field [0001] The invention relates to the field of engineering design drawing, in particular to a blueprint drawing and a preparation method thereof. Background technique [0002] Printing paper, commonly known as "blueprint paper", is a kind of chemical coating processing paper, which is specially used for various engineering design and mechanical manufacturing printing, and is an indispensable product in production, scientific research and construction. However, blueprint paper will turn yellow and fade after a long time of use, and it will become blurred when it is exposed to water during use. occupational health. Therefore, the traditional diazonium salt blueprints are gradually being abandoned. It is the development trend of the present era to use computer data files to print directly from printers, and to replace traditional printed blueprints with digital printing blueprints. However, the surface roughness of ordinary printing paper is difficult to meet th...
