preparation example Construction

[0050] The invention also discloses a method for preparing a high flame-retardant polyvinyl chloride flame-retardant wallpaper based on plant fiber base paper, which includes the following steps:

[0051] Step 1: take each component by formula;

[0052] Step 2: adding polyvinyl chloride resin PVC to liquid plasticizer cresyl diphenyl phosphate CDP, stirring and mixing at a high speed to obtain a PVC premix;

[0053] Step 3: adding ammonium polyphosphate APP into the PVC premix, stirring and mixing at a high speed to obtain PVC paste;

[0054] Step 4: Apply the PVC paste on the surface of the plant fiber base paper substrate by 50-100 mesh rotary screen printing, and the coating dosage is 100-140g / m 2, drying at 180-250° C. for 0.5-1.5 minutes to solidify and form, to obtain the high flame-retardant polyvinyl chloride flame-retardant wallpaper with plant fiber base paper as the base material.

Embodiment 1

[0128] Step 1: Weigh each component according to the formula:

[0129] 100 parts of polyvinyl chloride resin PVC;

Abstract

The invention discloses polyvinyl chloride flame-retardant wallpaper taking plant fiber raw paper as a base material. The polyvinyl chloride flame-retardant wallpaper comprises the base material and coating slurry, wherein the base material is plant fiber raw paper; the coating slurry is PVC (polyvinyl chloride) paste and the coating use amount is 100 to 140 g / m<2>; and the PVC paste comprises the following components: PVC resin, a liquid plasticizer cresyl diphenyl phosphate (CDP) and ammonium polyphosphate (APP). The plant fiber raw paper serves as the base material, the APP with relatively low price serves as an inorganic flame retardant and the CDP serves as the liquid plasticizer, so that the polyvinyl chloride flame-retardant wallpaper taking the plant fiber raw paper as the base material can be prepared and has low cost, high flame retardance, high smoke removing property and high mechanical properties.

Description

technical field [0001] The invention relates to the field of wallpaper, in particular to a highly flame-retardant polyvinyl chloride flame-retardant wallpaper with plant fiber base paper as a base material and a preparation method thereof. Background technique [0002] China is the world's largest producer and consumer of wallpaper products. According to the IGI (International Wallpaper Manufacturers Association) 2013 wallpaper sales statistics report, the total sales of wallpaper in China reached 186.7 million volumes, accounting for 29% of the world's consumption. At present, about 70% of indoor wallpaper products in the domestic market are polyvinyl chloride (PVC) wallpapers based on plant fiber base paper. China's national standard "Classification of Combustion Performance of Building Materials and Products" (GB 8624-2012), which was implemented on October 1, 2013, stipulates that the combustion performance level of wallpaper must reach B 1 Level, that is, the limiting ...
