Abstract

The invention provides an aqueous polyamide dispersion. The aqueous polyamide dispersion comprises the following components in parts by weight: 25-35 parts of polyamide micropowder, 2-6 parts of an emulsifier, 1-3 parts of an emulsifying dispersing agent, 1-3 parts of a wetting agent and 60-65 parts of water. The invention also provides a preparation method of the aqueous polyamide dispersion. Themethod comprises the following steps of: 1, adding 25-35 parts of the polyamide micropowder to 60-65 parts by weight of the water; 2, adding 2-6 parts by weight of the emulsifier to an aqueous polyamide micropowder solution prepared in the step 1; 3, adding 1-3 parts of the emulsifying dispersing agent to a solution prepared in the step 2; and 4, adding 1-3 parts of the wetting agent to a solution prepared in the step 3. The aqueous polyamide dispersion provided by the invention has the beneficial effects that the smoothness and the wearing easiness of a PVC (Poly Vinyl Chloride) labor protection glove are improved and the compatibility with other substances in a powder-based water slurry product is good.

Description

technical field [0001] The invention belongs to the technical field of chemical industry, and in particular relates to a polyamide aqueous dispersion and a preparation method thereof. Background technique [0002] Polyamide powder is a water-insoluble substance, which is a commonly used slip agent for injection molding materials. How to apply it to water-based systems and have better compatibility with other substances in water-based systems is a problem we need to solve key. First of all, to solve the problem of its dispersibility in water, because this kind of material is insoluble in water, it can only be made into micropowder, and the particle size should be controlled below 6 microns. It is also necessary to choose a suitable wetting agent, dispersing agent and operation method and for decentralized equipment. Utilizing polyamide material to make PVC labor protection gloves is a kind of purpose, but when the user wears the current labor protection gloves, it will be d...
