Embodiment 1

[0024] Example 1 DMM 2 For the production of butadiene rubber

[0025] Take 1,3-butadiene monomer, initiator and DMM 2 The solvent is added into four reaction kettles connected in series for reaction to prepare butadiene rubber, and the terminator ethanol and anti-aging agent 2,6-di-tert-butyl-4-methylphenol are added to the last kettle.

[0026] The control temperature of the first kettle is 2 The dissolution effect is good, and the prepared butadiene rubber will not appear glue-hanging phenomenon, and because DMM 2 Low impurity content will not cause fluctuations in the quality of butadiene rubber.

Embodiment 2

[0027] Example 2 DMM 2 For the preparation of neoprene adhesives

[0028] Take ethyl acetate, acetone, n-heptane and DMM 2 The mixed solvent A is obtained by blending at a mass ratio of 1:1:1:2, and the mixed solvent A prepared above is dissolved in neoprene rubber to obtain the neoprene adhesive.

[0029] The prepared chloroprene adhesive has good stability, no sediment, viscosity of 103mPa / s, peel strength of 5.8KN / m, and good rheological properties. DMM 2 The compounded mixed solvent is an excellent neoprene adhesive solvent.

Embodiment 3

[0030] Example 3 DMM 2 Replacing D20 environmentally friendly solvent oil for the preparation of bearing cleaning agent

[0031] Take DMM 2 , sodium metasilicate, sodium hydroxide and deionized water are mixed in a mass ratio of 8:2:2:82 to obtain a bearing cleaning agent. This bearing cleaner is completely non-foaming at 20-60°C and is especially suitable for quick cleaning processes.

Abstract

The invention belongs to the field of energy and chemical industry, and particularly relates to a new application of polyoxymethylene dimethyl ether as environment-friendly solvent oil. Polyoxymethylene dimethyl ether is compounded with conventional solvents selectively or in single-dosage form to be applied to the field of the preparation of rubber, adhesives, medicines, reclaimed rubber, binders or metal cleaners, or the field of the preparation of spices, oil for pharmaceutical intermediates, cleaners, dry cleaning agents, dyeing and printing auxiliaries, or paint coating thinners. The environment-friendly solvent oil containing polyoxymethylene dimethyl ether disclosed by the invention has the advantages of extremely low sulfur content, zero arene content, and the like, and has extremely good solubility, therefore, the environment-friendly solvent oil is low-sulfur and non-arene high-cleanability environment-friendly solvent oil.

Description

technical field [0001] The invention belongs to the field of energy and chemical industry, and specifically relates to the new application of polyoxymethylene dimethyl ether as an environment-friendly solvent oil. Background technique [0002] Solvent oil products are one of the five major categories of petroleum products, which are closely related to people's clothing, food, housing and transportation, and their application fields are also expanding. And it is widely used in various aspects such as cleaning of IC electronic components. [0003] At present, solvent oils on the market can be divided into ordinary solvent oils and special solvent oils. Ordinary solvent oil can be divided into 6#, 120# and 200# according to different fractions, and its production process is divided into two processes: cutting fractions and refining. Cutting is mainly to cut light straight-run fractions into appropriate narrow fractions or fractionate catalytic reforming raffinate, hydrogenate...
