Embodiment 1

[0041] A kind of production method of environment-friendly rubber product, it is the derivant that prepares phosphoric acid sulfuric acid with more than dibasic alcohol, phosphorus pentasulfide and divalent metal oxide as raw material, and the molar ratio of raw material in its production is as follows:

[0042] The molar ratio of dibasic or above alcohol to phosphorus pentasulfide is 2-5:2,

[0043] The molar ratio of divalent metal oxide to sulfuric acid is 2:3-1.

[0044] A method for producing environmentally friendly rubber products, characterized in that it comprises the steps of:

[0045] 4R(OH)n+P2S5----2[(HO)n-1RO]2PS2H+H2S

[0046] 2[(HO)n-1RO]2PS2H+MO---{[(HO)n-1RO]2PS2}2M+H2O

[0047] 2[(HO)n-1OR]2PS2H----[(HO)n-1RO]2PS4[(HO)n-1RO]2PS4P[(HOR)n-1O]2

[0048] Among them, sulfuric acid is prepared by the reaction of dibasic alcohols and phosphorus pentasulfide, the reaction temperature is 95 degrees Celsius to 100 degrees Celsius, the reaction humidity is below 90%...

Embodiment 2

[0052] Embodiment 2: The production steps are the same as in Embodiment 1, except that the temperature for controlling the reaction between the alcohols above the dibasic level and phosphorus pentasulfide is 95 degrees Celsius to 100 degrees Celsius, and the humidity is below 90%.

[0053] The product produced by replacing butanol with dihydric or higher alcohols as the raw material of alkyl thiophosphate is used as an accelerator and active agent in rubber mixing, which can not only reduce the adsorption of white carbon black on additives, At the same time, it is also environmentally friendly, does not produce carcinogenic nitrosamines, and can improve the working environment of mixing operators.

Abstract

The invention belongs to the technical field of environmental protection, and particularly relates to a production method of an environment-friendly rubber product.The environment-friendly rubber product is a thiophosphoric acid derivative prepared from raw materials including dihydric alcohol or one of polyhydric alcohols, phosphorus pentasulfide and bivalent metal oxide, wherein the molar ratio of the dihydric alcohol or one of polyhydric alcohols to the phosphorus pentasulfide is (2 to 5):2, and the molar ratio of the bivalent metal oxide to dithiophosphoric acid is 2:(3 to 1). The production method of the environment-friendly rubber product is characterized by comprising the following steps of 4R(OH)n+P2S5 2[(HO)n-1RO]2PS2H+H2S, 2[(HO)n-1RO]2PS2H+MO {[(HO)n-1RO]2PS2}2M+H2O, and 2[(HO)n-1OR]2PS2H [(HO)n-1RO]2PS4[(HO)n-1RO]2PS4P[(HOP)n-10]2. The production method is used for solving the problem of a large quantity of pollutants generated when the rubber product is produced at present.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and specifically relates to a production method of an environmental protection rubber product. Background technique [0002] As a filler for rubber products, silica has advantages in wet grip and low rolling resistance. Now it is more and more used, but silica has strong adsorption, which will absorb the additives in the rubber formula and reduce its Efficiency, increase the use of additives, making the production cost rise. [0003] In addition, general-purpose accelerators will produce nitrosamine carcinogens during rubber mixing, which seriously affects the physical and mental health of rubber mixers. Therefore, many high-risk accelerators such as NOBS have been replaced by accelerators that do not produce nitrosamines. . Alkyl thiophosphates and esters, because their molecular structure does not contain secondary amine structures, do not produce nitrosamines, the US Food an...
