The macromolecule absorbent is characterized in that the macromolecule absorbent comprises, by weight, the following raw materials of 26-28 parts of cyclohexyl acrylate, 17-20 parts of butyl acrylate, 3-4 parts of polylactic acid, 3-4 parts of nanosilicon dioxide, 0.3-0.4 part of gamma-methacrylamide acyloxy propyl trimethoxy silane, 0.16-0.2 part of acrylic ester, 4-5 parts of carboxymethylcellulose, 22-24 parts of ethyl acetate, 1-1.2 parts of benzoyl peroxide, 0.9-1.2 parts of p-methylstyrene, 1.8-2.5 parts of divinyl benzene, 1-2 parts of nano aluminum hydroxide, 0.05-0.07 part of silane coupling agent kh450, 1-1.2 parts of di (isooctyl) phosphate, 0.5-0.6 part of silicone oil and moderate distilled water. The macromolecule absorbent with modified high thermal stability based on the nanosilicon dioxide polylactic acid is of a double-layer porous structure, a big volume expansion ratio is achieved, the thermal stability is high, and certain fire resistance is achieved.

Description

technical field [0001] The invention relates to the field of materials, in particular to a polymer absorbent with high thermal stability based on nano-silica polylactic acid modification and a preparation method thereof. Background technique [0002] With the increasing frequency of offshore oil extraction and transportation, oil spill accidents from offshore oil tanks occur frequently, as well as the discharge of oily sewage. When oil enters the ocean, it will cause immeasurable harm to the natural environment, aquaculture, shallow water coast, dock industry, etc. At present, most of the treatment of these pollution sources is to absorb the slick oil through oil-absorbing materials to purify the pollution sources. [0003] Traditional oil-absorbing materials are mostly inorganic and organic materials that are modified, mixed, and pressed by physical methods. According to their oil-absorbing mechanism, they can be divided into occlusion-type oil-absorbing materials, gel-type...
