Abstract

The invention provides antistatic graphene latex slurry as well as a process and application thereof. The antistatic graphene latex slurry comprises the following components in parts by weight: 70-90 parts of natural latex, 2-5 parts of a vulcanizing agent, 2-5 parts of an antistatic agent and 2-8 parts of functionalized graphene; the functionalized graphene comprises the following raw material components in percentage by mass: 8-15% of graphene oxide, 2-7% of an alkaline compound, 5-10% of octadecylamine and 70-85% of a reducing agent. The process for preparing the antistatic graphene latex slurry comprises the following steps: uniformly mixing the antistatic agent, the vulcanizing agent, the water and optional accelerant and antioxidant to obtain a mixture A; uniformly mixing the mixture A and the functionalized graphene to obtain a mixture B; and finally, uniformly mixing the mixture B with the natural latex to obtain the antistatic graphene latex slurry. The antistatic graphene latex slurry provided by the invention has better antistatic property and is suitable for preparing back cushions or mattresses.

Description

technical field [0001] The invention belongs to the field of natural rubber composite materials, and in particular relates to an antistatic graphene latex slurry and its technology and application. Background technique [0002] Natural rubber, a natural polymer composed of more than 90% isoprene, is a self-reinforcing rubber with excellent mechanical properties such as abrasion resistance, tensile strength and elasticity, etc., and is widely used in such as Automobile tires and seats, medical supplies, aviation suits, shock absorbers, household items and other fields. Natural rubber is a non-polar rubber with high volume resistivity, but when its surface is subject to movement, stress and friction, it is easy to cause charge accumulation and form static electricity, and the release of static electricity is likely to endanger human health and accelerate the surface of rubber products. of aging. Therefore, how to eliminate the hazards of static electricity is an important ta...
