Abstract

The invention discloses a waste petroleum phenolic residue modified sulfamate high-efficiency water reducing agent and a preparation method thereof. The waste petroleum phenolic residue modified sulfamate high-efficiency water reducing agent is prepared from the following components in parts by weight: 130-140 parts of sodium sulfanilate, 100-200 parts of 80% waste petroleum phenolic residues, 30-60 parts of concentrated sulfuric acid, 50-60 parts of phenol, 150-180 parts of formaldehyde, 15-30 parts of 30% liquid caustic soda, 1-10 parts of dodecyl diphenyl ether sodium disulfonate and 180-260 parts of water. The waste petroleum phenolic residue modified sulfamate high-efficiency water reducing agent disclosed by the invention is low in production cost, the slump loss and the bleeding phenomenon of concrete can be remarkably reduced, the slump resistance can be improved, the peaceability can be improved, a remarkable concrete reinforcing effect can be achieved, and the social and economic benefits are remarkable.

Description

technical field [0001] The invention relates to the field of concrete materials, in particular to a preparation method of a petroleum waste phenol slag modified sulfamate high-efficiency water reducer. Background technique [0002] High-efficiency water reducer, also known as superplasticizer or dispersant, is an admixture that can reduce the amount of mixing water and significantly increase the strength of concrete under the condition that the slump of concrete is basically the same. According to the different varieties of production raw materials, it is divided into: naphthalene-based water-reducer, anthracene-based water-reducer, methyl-naphthalene-based water-reducer, coumarone-based water-reducer, melamine-based water-reducer, sulfamate water-reducer , fatty acid water reducer, polycarboxylate water reducer, etc. At present, high-efficiency water-absorbing agents widely used in China are naphthalene-based, melamine-based and water-reducing agents compounded from them, ...
