Problems solved by technology

Reclaimed rubber has always been an important raw material for the world's rubber industry. On the one hand, it can replace rubber and alleviate the serious shortage of rubber; on the other hand, it enables waste rubber to be recycled and reused, solving the problem of waste rubber polluting the environment. The irritating odor produced in the environment limits the production and application range of recycled rubber

preparation example Construction

[0031] The present invention provides a preparation method for a deodorant for regenerated rubber described in the above technical solution, comprising the following steps:

[0032] (1) mixing benzyl benzoate and N,N-dimethylformamide to obtain a compound solution;

[0033] (2) Ferrous sulfate, sodium dodecylbenzenesulfonate and calcined clay are mixed to obtain a mixed powder;

[0034] (3) mixing the composite liquid of the step (1) with the mixing powder of the step (2) to obtain a deodorant for regenerated rubber

[0035] The steps (1) and (2) are not in chronological order.

[0036] The invention mixes benzyl benzoate and N,N-dimethylformamide to obtain a complex solution. The present invention has no special requirements on the mixing method, and a mixing method well known to those skilled in the art can be used. In the present invention, it is preferred to mix without stirring. Since the surface tension of benzyl benzoate is 44.0 dyn / cm and that of N,N-dimethylformami...

Embodiment 1

[0046] In parts by mass, put 10 parts of benzyl benzoate and 5 parts of N,N-dimethylformamide, a total of 7.5g, into a container and mix to obtain a compound solution;

[0047] Put 65 parts of ferrous sulfate heptahydrate, 20 parts of sodium dodecylbenzenesulfonate, and 100 parts of calcined clay, a total of 92.5g, into the mixer, and stir for 5 minutes to obtain a mixed powder;

[0048] Pour the composite liquid onto the mixed powder in the blender, stir for 5 minutes, release the deodorant used for regenerated rubber, and set aside.

[0049] Mix the waste rubber to be treated, water, softener, activator and prepared deodorant for regenerated rubber, control the amount of deodorant used for regenerated rubber to be 3‰ of the quality of waste rubber, and carry out desulfurization reaction, The regenerated rubber is obtained, and no irritating odor is produced during the rubber regeneration process, and the production environment has passed the acceptance of the environmental p...

Embodiment 2

[0051] In parts by mass, 5 parts of benzyl benzoate and 4 parts of N,N-dimethylformamide, a total of 9 g, were put into a container and mixed to obtain a composite solution;

[0052] Put 60 parts of ferrous sulfate heptahydrate, 16 parts of sodium dodecylbenzenesulfonate, and 103 parts of calcined pottery clay, a total of 179g, into a blender, and stir for 4 minutes to obtain a mixed powder;

[0053] Pour the composite liquid onto the mixed powder in the blender, stir for 6 minutes, and release the deodorant used for regenerated rubber.

[0054] Mix the waste rubber to be treated, water, softener, activator and prepared deodorant for regenerated rubber, control the amount of deodorant used for regenerated rubber to be 2.5‰ of the quality of waste rubber, and carry out desulfurization reaction. A deodorant for regenerated rubber is obtained, no irritating odor is produced during the rubber regenerated process, and the production environment has passed the inspection and accepta...

Abstract

The invention provides a deodorizing agent for regenerated rubber as well as a preparation method and application thereof. The deodorizing agent for the regenerated rubber provided by the invention comprises the following components in parts by mass: 60 to 70 parts of ferrous sulfate, 15 to 25 parts of sodium dodecyl benzene sulfonate, 5 to 15 parts of benzyl benzoate, 3 to 7 parts of N,N-dimethylformamide, and 95 to 105 parts of calcined pottery clay. By adopting the deodorizing agent provided by the invention, the pungent smell produced in the production and application process of the regenerated rubber can be removed.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to a deodorant for recycled rubber, a preparation method and application thereof. Background technique [0002] The disposal of waste rubber is one of the serious problems faced at present. The discarded rubber cannot be degraded naturally for a long time, resulting in black pollution that is more difficult to deal with than plastic pollution (white pollution). On the other hand, precious rubber resources are wasted. Conscientious and proper disposal of waste rubber has far-reaching positive and practical significance for making full use of renewable resources, getting rid of the lack of natural resources, reducing environmental pollution, and improving the living environment of the people. [0003] Nowadays, waste rubber is mostly recovered and prepared into recycled rubber to realize the treatment of waste rubber. Reclaimed rubber has always been an important raw mat...
