Melamine impregnated paper body paper printing ink-absorbing coating and preparation method thereof

Abstract

The invention belongs to the technical field of melamine impregnated paper, and particularly relates to a melamine impregnated paper body paper printing ink-absorbing coating and a preparation method thereof. The coating comprises the following components in percentage by mass: 36-56% of a waterborne polyurethane dispersion, 3-8% of silicon dioxide, 0.1-0.3% of a defoaming agent, 0.3-0.7% of a wetting agent, 1-5% of a film forming auxiliary agent, 0.1-0.3% of a multifunctional additive, 0.5-2.0% of a thickening agent and the balance of water. The melamine impregnated paper body paper printing ink-absorbing coating disclosed by the invention is coated on the surface of body paper, is obtained by matching a waterborne polyurethane dispersion and silicon dioxide with a plurality of auxiliaries, and can effectively improve the water resistance and color fidelity of the melamine impregnated paper; and the melamine impregnated paper which is high in color fidelity, uniform in color development, high in wet strength and good in water resistance can be obtained.

Description

technical field [0001] The invention belongs to the technical field of melamine-impregnated paper, and in particular relates to a melamine-impregnated paper base paper printing ink-absorbing coating and a preparation method thereof. Background technique [0002] The full name of melamine impregnated paper is melamine impregnated film paper, also known as "melamine" paper, which is impregnated with amino resin (melamine formaldehyde resin and urea formaldehyde resin) through a plain base paper or printed decorative paper and dried to a certain degree, with a certain resin content and volatile content of gummed paper. Melamine-impregnated paper is widely used in panel furniture, most of which are in the form of low-pressure short-cycle, that is, under high temperature and high pressure, press and paste for tens of seconds to make decorative panels. In recent years, the impregnated film paper combined with the wood grain of the steel plate has been used to produce synchronous ...

AI Technical Summary

Problems solved by technology

[0003] At present, domestic melamine-impregnated paper base paper is divided into two types: imported and domestic. The price of imported base paper is 3-5 times that of domestic base paper. Imported base paper has high color fidelity, good wet strength, good water resistance, and uniform fiber distribution. The impregnated paper produced is more beautiful and of good quality, while the domestic base paper has poor color fidelity, uneven color development, poor wet strength, and poor water resistance due to its low ash content and poor fiber distribution uniformity. , the appearance of the impregnated paper produced is not good, and the quality is relatively poor
