Abstract

The invention discloses a preparation method of an anti-ultraviolet mattress bottom layer fabric coating. The anti-ultraviolet mattress bottom layer fabric coating is prepared from the following raw materials in parts by mass: 60-80 parts of waterborne polyurethane resin, 40-60 parts of deionized water, 2-5 parts of a neutralizer, 10-30 parts of nano titanium dioxide, 5-10 parts of nano zinc oxide, 5-15 parts of nano silicon dioxide, 5-15 parts of acetone and 2-8 parts of a cross-linking agent. The preparation process is simple; nano titanium dioxide and nano zinc oxide are added into a finished product, so that the ultraviolet resistance of existing fabric coating is improved; and nano silicon dioxide is reasonably proportioned and added, the ultraviolet resistance is greatly improved byutilizing the small-size effect, the surface effect and the macroscopic quantum tunnel effect of nano materials; and the waterborne polyurethane resin is used as the raw material, thereby the finishedproduct is more environment-friendly.

Description

technical field [0001] The invention relates to the technical field of fabric coating, in particular to a method for preparing an anti-ultraviolet mattress bottom fabric coating. Background technique [0002] Coated fabric is a kind of fabric treated by special process, which can form a layer of uniform covering glue on the surface of the fabric, so as to achieve waterproof, windproof and other functions. [0003] Ultraviolet refers to the general term for radiation with wavelengths from 10nm to 400nm in the electromagnetic spectrum, which cannot cause people's vision. In 1801, German physicist Reiter discovered that a section outside the purple end of the sunlight spectrum can make photographic negatives containing silver bromide sensitive, so Discovered the existence of ultraviolet rays, ultraviolet rays can be used to sterilize, too much ultraviolet rays entering the body can cause skin cancer to the human body. [0004] At present, the coating of the bottom surface of t...
