Abstract

The invention discloses a high-viscosity environment-friendly plasticizer and a preparation method and application thereof. The plasticizer is prepared by mixing n-alkane and methyl palmitoleate in aratio of 3: 7, wherein n-alkane and methyl palmitoleate are taken as chlorination raw materials. The preparation method comprises the steps of adding n-alkane and methyl palmitoleate into a reaction kettle and carrying out chlorination reaction step by step. The high-viscosity environment-friendly plasticizer can be applied to preparation of an environment-friendly foam caulking agent. The plasticizer prepared by the invention does not contain short-chain chlorinated paraffin, is light yellow in color and free of peculiar smell, can inhibit oil precipitation, and is excellent in low-temperature resistance. The prepared foam has the advantages of environment-friendliness, high viscosity, good foam holes, no shrinkage, strong controllability, good emulsifying effect and stable performance atlow temperature.

Description

technical field [0001] The invention relates to the technical field of production and processing of building materials, and more specifically relates to a high-viscosity environment-friendly plasticizer and its preparation method and application. Background technique [0002] Polyurethane foam sealant has excellent properties such as waterproof, thermal expansion and contraction resistance, heat insulation, and sound insulation, and is widely used in the filling and sealing of building door and window side seams, component expansion joints and holes. At present, the main plasticizer of polyurethane foam caulks on the market is chlorinated paraffin. Chlorinated paraffin is not easy to biodegrade and is a non-renewable petrochemical product. It will decompose and produce toxic chloride gas after burning. Chlorinated paraffins containing SCCP short chains are highly toxic to aquatic organisms and have long-term negative effects on the aquatic environment. They may cause cancer ...
