Embodiment 1

[0023] A kind of safe environment-friendly rubber solvent that replaces gasoline, and its raw material composition and parts by weight are:

[0024] 15-20 parts of C10 normal paraffin solvent oil;

[0025] 79-85 parts of C11 normal paraffin solvent oil;

[0026] Vaseline 0.1-0.5 parts.

[0027] The preparation method of the safe and environment-friendly rubber solvent that substitutes gasoline as above, the steps are as follows:

[0028] First, heat and melt the formulated amount of vaseline until it becomes a clear and transparent liquid, then add C10 n-alkane solvent oil and stir until it is clear and transparent, then add C11 n-alkane solvent oil to it, and stir evenly to obtain a safe and environmentally friendly rubber solvent that can replace gasoline .

[0029] Preferably, the vaseline is heated and melted to a temperature of 60±1°C when it becomes a clear and transparent liquid.

[0030] The use method of the safe and environment-friendly rubber solvent that substi...

Embodiment 2

[0034] A kind of safe and environment-friendly rubber solvent that replaces gasoline, its raw material composition and its weight are respectively (take the safe and environment-friendly rubber solvent that 1000g replaces gasoline as an example):

[0035] C10 normal paraffin solvent oil ratio 200g;

[0036] C11 normal paraffin solvent oil ratio 798g;

[0037] Vaseline ratio 2g.

[0038] The preparation method of the above-mentioned safe and environment-friendly rubber solvent replacing gasoline is as follows: first, heat and melt the formulated amount of vaseline to a clear and transparent liquid (about 60°C), add C10 normal paraffin solvent oil to it and stir until it is clear and transparent, and then add C11 Normal paraffin solvent oil can be stirred evenly.

[0039] When in use, mix the above-mentioned safe and environmentally friendly rubber solvent that replaces gasoline with raw rubber at a mass ratio of 3:1, and leave it for 24 hours to obtain a stable raw rubber sol...

Abstract

The invention relates to a safe and environment-friendly rubber solvent capable of replacing gasoline. The safe and environment-friendly rubber solvent comprises the following raw materials in parts by weight: 15-20 parts of C10 n-alkane solvent oil, 80-85 parts of C11 n-alkane solvent oil, and 0.1-0.5 part of vaseline. The rubber solvent has the characteristics of good rubber dissolving property,high volatilization speed, small degreasing property to skin, no toxicity, no harm, low cost and the like, and has excellent application prospect, wherein the closed-cup flash point of the rubber solvent is more than 60 DEG C.

Description

technical field [0001] The invention belongs to the technical field of rubber solvents, in particular to a safe and environment-friendly rubber solvent replacing gasoline, and a preparation and use method. Background technique [0002] In the processing of some rubber products with complex shapes, such as slippers, it is often necessary to dissolve and bond the raw rubber, make it into an appropriate shape, and then proceed to the subsequent vulcanization process. Solid unvulcanized rubber can be dissolved in some organic solvents, but as a polymer material, its dissolution process is significantly different from that of solid low-molecular materials. First of all, the dissolution process is slow and cannot be completed in an instant like low-molecular materials. Second, the whole process is divided into two stages: swelling first and then dissolving, not in one step. Because in the rubber solution, the rubber macromolecules as the solute are bulky, at the micron level, an...
