Abstract

The invention relates to the technical field of carpet production, in particular to a flame-retardant carpet based on foamed coating tailings and a preparation process thereof. The flame-retardant carpet comprises a carpet fabric layer and a flame-retardant coating, wherein the flame-retardant coating is prepared from, by weight percentage, 40-60% of the foamed coating tailings, 4-6% of a foamingagent, 10-20% of a crosslinking agent, 20-25% of expandable graphite, 2-3% of a leveling agent, 1-2% of a thickening agent and 3-5% of water. A process for preparing the flame-retardant carpet based on the foamed coating tailings is also included. The flame-retardant carpet prepared by utilizing the foamed coating tailings has a good flame retarding effect and high safety performance, the preparation process is simple, recycling of the coating tailings can be realized without affecting the quality of the carpet, and the comfort of the carpet is ensured.

Description

technical field [0001] The invention relates to the technical field of carpet production, in particular to a flame-retardant carpet based on foamed coating tails and a preparation process thereof. Background technique [0002] Coating processing is a common process in textile processing. It is mainly used to change and improve the performance of textiles. It is a commonly used and mature processing method for coated textile companies. Coating tails refer to the small amount of coating material remaining during the coating process of fabrics. [0003] At present, there are many enterprises producing coated textiles, and it is impossible for any enterprise to use up all the prepared coatings during the coating process. Every time the coating process is completed, there is always a small amount of coating tailings left. For a long time, most enterprises have treated these remaining tailings as waste. The treatment plan mainly includes: first, sedimentation-press filtration-la...
