High-temperature-resistant paper for steel sign

Abstract

The invention specifically relates to high-temperature-resistant paper for a steel sign, which belongs to the field of specialty paper. The high-temperature-resistant paper is prepared by subjecting a vegetable fiber, a filling material with a high proportion and a high retention rate, an additive and the like to paper making so as to obtain high-temperature-resistant raw paper, then preparing a high-temperature-resistant coating from a pigment with good spreadability, high-temperature-resistant latex, a PAPU water resisting agent, CMC, a lubricant and the like and coating a single surface of the raw paper with the high-temperature-resistant coating. The high-temperature-resistant paper provided by the invention can be used for preparation of signs and labels for high temperature industries like the steel metallurgy industry; specifically speaking, a layer of a polyester film is compounded between uncoated surfaces of two pieces of high-temperature-resistant paper to prepare a high-temperature-resistant sign which has a good printing effect, does not have fading and powder-falling when put in an environment with a temperature of about 300 DEG C for 2 to 3 min, can resist acid and endure the sun and rain and has lower cost and environment friendliness compared with a traditional aluminum sign.

Description

technical field [0001] The invention relates to the technical field of printing materials, in particular to a high-temperature-resistant paper for steel signs. Background technique [0002] Steel products of different types and origins have their own identification card, which is the steel product label. A high-quality signage can give users a high degree of trust in the product. The general steel signage is a layer of polyester film compounded between two layers of paper, so that the signage has good printing adaptability while meeting high tearing and crispness. [0003] Some steel materials will hang signs on their ends shortly after hot pressing. At this time, the temperature of the steel may be as high as 300 degrees, which requires that the signs be resistant to instantaneous high temperature, and the signs will change less or basically unchanged, otherwise it will cause Users are worried about product quality, which requires the special research and development of h...
