High-oil-absorption resin and preparation method thereof

Abstract

The invention relates to high-oil-adsorption resin and a preparation method thereof, and belongs to the technical field of oil-adsorption resin. The high-oil-adsorption resin comprises an oil phase and a water phase, wherein the oil phase is prepared from, by weight, 4-8 parts of divinyl benzene, 20-30 parts of styrene, 20-30 parts of n-lauryl acrylate, 20-30 parts of butyl acrylate, 20-30 parts of butadiene rubber, 3-9 parts of azodiisobutyronitrile and 40-50 parts of methylbenzene, and the water phase is prepared from, by weight, 5-9 parts of polyvinyl alcohol, 10-20 parts of gelatin, 5-8 parts of NaCl, 5-10 parts of CaCO3 and 500-600 parts of deionized water. According to the high-oil-adsorption resin and the preparation method thereof, the high-oil-adsorption resin is prepared by taking adopting a suspension polymerization technology, taking the styrene, the n-lauryl acrylate, the butyl acrylate and the butadiene rubber as the raw materials, taking the azodiisobutyronitrile as an initiator and taking the divinyl benzene as a cross-linking agent, and the adsorption quantity of the oil-adsorption resin is greatly increased.

Description

technical field [0001] The invention relates to a resin and a preparation method thereof, more specifically, the invention relates to a high oil-absorbing resin and a preparation method thereof, belonging to the technical field of oil-absorbing resins. Background technique [0002] High oil-absorbing resins can absorb various oily substances, and are especially suitable for the adsorption and recovery of oil slicks or spilled oils on water surfaces and other solid surfaces. At the same time, it can also be used for separation and purification of oily wastewater. [0003] This type of high oil-absorbing resin has a certain cross-linked network structure, good toughness and elasticity, and also has good heat brushing, cold resistance, not easy to age, and fast oil absorption. It overcomes the shortcomings of traditional oil-absorbing materials. The cross-linked molecules have a three-dimensional cross-network structure, and there are certain micropores inside. The resin can b...

Problems solved by technology

[0006] The purpose of the present invention is to solve the problem that although the oil-absorbing resin in the prior art can be used to recover oil slicks on the water surface, the adsorption capacity is still not large enough. It provides a high oil-absorbing resin that can greatly increase the adsorption capacity of the oil-absorbing resin, which is very suitable for use Recovery of oil slick on water surface
