Abstract

The invention discloses a latex and fiber composite foaming material and a preparation method thereof. The latex and fiber composite foaming material is prepared by mixing the following components in parts by weight: 10-30 parts of fibers, 100 parts of natural latex, 0.3-0.8 part of sodium dodecyl benzene sulfonate, 1.6-3.5 parts of sulfur, 0.6-3.5 parts of zinc dimethyldithiocarbamate, 0.8-2.3 parts of anti-aging agent RD, 15-25 parts of aluminum hydroxide, 1.5-3 pars of zinc oxide, 2.0-2.5 parts of sodium fluorosilicate, 1-8 parts of 3 mass percent formaldehyde and 5-10 parts of latex foaming agent; and the method comprises the steps of preparing the latex, molding the fibers, foaming, putting into a mold, vulcanizing, demolding, washing, drying and the like. The latex and fiber composite foaming material has good elasticity, stable foam structure and good comfort, and overcomes the defects that an un-foamed fiber elastic material is relatively hard and a sponge material is soft in supporting and poor in breathability.

Description

technical field [0001] The invention relates to a latex fiber composite foaming material and a preparation method thereof, belonging to the technical field of latex materials. Background technique [0002] At present, unfoamed fiber elastic materials are used in the production of various sitting and lying materials, packaging materials, sound insulation and noise reduction materials and their finished products, but the unfoamed fiber elastic materials are hard and the sponge materials are soft. , poor air permeability, and can not be cut arbitrarily, the existing processing method is easy to collapse during the foaming process, the foam structure is unstable, the quality is poor, and the yield is low, so the existing materials are insufficient. Contents of the invention [0003] The object of the present invention is to provide a kind of latex fiber composite foaming material and preparation method thereof, through production methods such as compounding glue, fiber moldin...
