Abstract

The invention relates to a preparation method of an antifouling and anticorrosive tablecloth material, and belongs to the technical field of household materials. The method prepares the antifouling and anticorrosive tablecloth material by attaching hydrophobic nanopowder to a needle-punched nonwoven fabric of a polysulfonamide fiber and adding vinyl trimethoxysilane or stearic acid, the hydrophobic nanopowder is composed of nano-silica and nano-alumina, hydroxyl groups on the nano-silica and nano-alumina can react with amino groups in the polyethyleneimine, through a hydrogen bond and a van der Waals force, the surface of the needle-punched nonwoven fabric of the polysulfonamide fiber is adsorbed with a layer of polyethyleneimine monolayer, under the action of dicyclohexylcarbodiimide, thestearic acid can be dehydrated and condensed with the polyethyleneimine and further grafted with a long carbon chain, and a layer of long chain carbon molecules having a hydrophobic effect are grownon the surfaces of the nano-silica and the nano-alumina, thereby improving the hydrophobicity and self-cleaning ability of the needle-punched nonwoven fabric of the polysulfonamide fiber.

Description

technical field [0001] The invention relates to a preparation method of an antifouling and corrosion-resistant tablecloth material, which belongs to the technical field of household materials. Background technique [0002] The higher the consumption level of urban and rural residents, the higher the consumption expectations. As the disposable income of domestic urban and rural residents continues to grow, consumers' expectations for tablecloth products are also rising. The current tablecloth market environment is changing from "practical" to "decorative". The tablecloth market is facing differentiation of product levels. The product will become the mainstream of the market. [0003] At the same time, with rising consumption expectations in the tablecloth market, consumption of mid-to-high-end household items is becoming more and more common, and traditional tablecloths with low quality, no design, and no brand will be gradually eliminated. Mid-to-high-end and brand-name ta...
