Problems solved by technology

In recent years, expandable graphite has attracted increasing attention due to its excellent flame retardant effect, but expandable graphite is not widely used in latex
Because the expandable graphite itself is scaly and gray-black in color, the dispersion uniformity is not good when it is directly added to latex, resulting in slightly poor performance and appearance color, which greatly limits the use of expandable graphite in latex sponge materials. application in

Abstract

The invention discloses an environment-friendly flame-retardant latex pillow and a preparation method thereof. The invention provides a preparation method for producing a flame-retardant latex pillowby using an intumescent flame retardant. The preparation method of the flame-retardant latex pillow comprises the following steps of: (1) mixing and stirring natural latex, a vulcanizing agent, a foaming agent and a foam stabilizer dispersion according to a certain ratio, and performing ripening; and (2) adding environment-friendly expandable graphite into the ripened latex, dispersing the substances uniformly, and then conducting foaming, mold injection, vulcanizing and drying. The latex pillow product is coagulated by carbon dioxide, expandable graphite is uniformly dispersed in the preparedlatex pillow core, and the pillow core has good flame retardance in the air and can be self-extinguished when being away from fire. According to the flame-retardant latex pillow, the use safety is improved while the excellent performance of a traditional latex pillow is kept.

Description

technical field [0001] The invention relates to the technical field of latex product production, in particular to an environment-friendly flame-retardant natural latex pillow and a preparation method thereof. Background technique [0002] No matter at home or abroad, there are very few studies on the flame retardancy of natural latex foam products. With the development of the times and the progress of social economy, natural latex foam products are widely used in various fields and industries. Both require natural latex foam products to have better flame retardancy. Therefore, in the face of this market demand and technology gap, some domestic enterprises are also trying to set up research projects. [0003] Expandable graphite (EG) is a special graphite crystal compound, which will start to expand when heated to a certain extent, and the expanded graphite will change from the original scale shape to a worm shape with a very low density, forming a good thermal insulation la...
