Abstract

The invention discloses a stable fluorescent whitening agent for PVC and plant fibers, which comprises 20-60% of a fluorescent whitening agent, 1-4% of a dispersant, 0.05-0.3% of blue phase permanent violet RL, 0.1-0.4% of polyethylene glycol, 10-20% of anhydrous sodium sulphate, 2-6% of a coupling agent, 1-5% of a surfactant, 0.5-2% of an ultraviolet light absorber, 0.3-1% of a sterilizing agent, 0.04-0.7% of an insect repellent agent, 0.2-3% of an initiator, 0.1-0.5% of an antifreezing agent, 0.3-1.5% of a defoaming agent, and the balance of water. And the balance of water. The fluorescent whitening agent prepared by the invention not only has a good whitening effect, obviously improves the whiteness of PVC and plant fibers, but also has good stability, is not easy to discolor and can tolerate the change of moisture and temperature, and the improved PVC and plant fibers are very favorable for manufacturing flowerpots. The antibacterial and insect-resistant capabilities are also realized; the invention discloses a preparation method of a stable fluorescent whitening agent for PVC (polyvinyl chloride) and plant fibers, which simplifies the production steps, and is beneficial to improving the product quality and increasing the production efficiency.

Description

technical field [0001] The invention relates to the technical field of whitening agents, in particular to a stable fluorescent whitening agent for PVC and plant fibers and a preparation method thereof. Background technique [0002] PVC and plant fibers are important raw materials for making flowerpots. At present, as people pay more attention to indoor landscapes, it has become a popular trend to cultivate plants at home. The decoration of plants in the room can not only improve the aesthetics, but also make the air fresher and ease people's emotions. [0003] In order to make the plants have a better decorative effect, they are often matched with beautiful flowerpots, so the requirements for the raw materials of the flowerpots are also very high. When PVC and plant fibers are used as the main material of flower pots, it is often necessary to add whitening agents to improve the surface color. [0004] However, the brighteners used for PVC and plant fibers are often ineffec...
