Abstract

The invention discloses a calcium sulfate whisker / styrene-butadiene latex composite foaming material and a preparation method thereof. Raw materials preparing the calcium sulfate whisker / styrene-butadiene latex composite foaming material comprise, in parts by weight: 50 to 70 parts of styrene-butadiene latex, 8 to 20 parts of natural rubber latex, 5 to 20 parts of modified calcium sulfate whiskers, 0.5 to 4 parts of a modified glass fiber, 2 to 6 parts of talcum powder, 0.02 to 0.15 part of calcium chloride, 2 to 6 parts of zinc oxide, 3 to 8 parts of liquid soap and 0.5 to 3 parts of benzoylperoxide, wherein the solid content of the styrene-butadiene latex is 55 to 68 percent. The calcium sulfate whisker / styrene-butadiene latex composite foaming material prepared by the method is low indensity, light in weight, high in bearing capacity, excellent in mechanical property such as breaking elongation and toughness and high in resilience performance; furthermore, the preparation method is simple, and the preparation process is easy to operate; a product is high in size stability.

Description

technical field [0001] The invention relates to the technical field of polymer processing, in particular to a calcium sulfate whisker / styrene-butadiene latex composite foaming material and a preparation method thereof. Background technique [0002] SBR latex is a stable emulsion formed by polymerization of butadiene and styrene at low temperature. According to the content of styrene, emulsifier and polymerization temperature, there are many kinds of products; natural rubber has high elasticity at room temperature, It has high mechanical strength, but it is not resistant to aging. Compared with natural rubber latex, styrene-butadiene latex has better wear resistance, heat resistance and strength, and is widely used in tire cord dipping, paper dipping, latex coating, latex cement, coating and fiber treatment, etc. However, the research and application of foamed products prepared with styrene-butadiene latex as the main material are less. [0003] Foaming materials are widely...
