Problems solved by technology

According to its main function, it can be divided into anti-thermal oxygen aging agent, anti-ozone agent, harmful metal ion inhibitor, anti-fatigue agent, ultraviolet absorber, anti-cracking agent, etc. There are many common rubber anti-aging agents used in latex products. Questions, such as: anti-aging agent 2245 has a comprehensive protective effect on latex products, has a good anti-slip effect on heat, oxygen and flex fatigue aging, and has an anti-slip effect on harmful metals, but the anti-aging agent will be damaged when exposed to strong sunlight. Discoloration will affect the performance of latex products, while the anti-aging agent SP has the effect of preventing ultraviolet oxidation and thermal oxidation, and its pollution is small, and various anti-aging agents will produce additive and synergistic effects when mixed together. Can solve a variety of aging protection problems, properly used, can obtain synergistic effects

Embodiment 1

[0018] Example 1 ： A latex anti-aging agent, comprising the following components in parts by weight: 40-50 parts by weight of anti-aging agent SP, 20-30 parts by weight of anti-aging agent 616, 25-30 parts by weight of anti-aging agent 2246, wherein the anti-aging agent The ratio of parts by weight between SP, antiaging agent 616 and antiaging agent 2246 is 4-5:2-3:2.5-3; Ratio, as shown in the table below, the ratio with better practical effect is: antiaging agent SP 40 parts by weight, antiaging agent 616 25 parts by weight, antiaging agent 2246 25 parts by weight, wherein antiaging agent SP, antiaging agent 616 The weight and number ratio of anti-aging agent 2246 is 40:25:25.

[0019]

[0020] The anti-aging agent SP of the present invention is styrenated phenol, which can improve the heat resistance and anti-oxidative aging performance of the product, and the anti-aging agent 616 is the butylation reaction of p-cresol and dicyclopentadiene The resulting polyphenol c...

Embodiment 2

[0021] Example 2 ： The elastic carrier of the present invention is one or two mixtures in natural latex and synthetic latex; the preferred elastic carrier is 10-15 parts by weight, and the present invention is applied to latex products, and the elastic carrier is a similar latex carrier, Guarantee the mixing effect of anti-aging agent and latex products during use.

[0022] The dispersant of the present invention is stearic acid, and the preferred dispersant is 2-3 parts by weight. The elastic carrier of the present invention is latex, and the dispersion effect of stearic acid in elastic latex is better. Microcrystalline wax and liquid paraffin The dispersion effect is poor.

[0023] The preferred carbon black of the present invention is 0.1-0.5 weight part, and the weight and number ratio of described dispersant and carbon black is 10:1, when the weight ratio of carbon black is bigger, the micelle hardness of generation is bigger, does not It is beneficial to fully mix wi...

Embodiment 3

[0024] Example 3 ： The preparation steps of a kind of latex antioxidant of the present invention are:

[0025] 1) Stir and mix the anti-aging agent SP and the elastic carrier under heating regulation; the anti-aging agent SP is liquid at normal temperature, and the latex is an easy-melt colloid, which is convenient to mix and melt at low temperature.

[0026] 2) Stir for 1 hour, add dispersant and carbon black in sequence, stir well for 30 minutes, cool to room temperature, and obtain a liquid mixture, use dispersant to accelerate the mixing effect of anti-aging agent SP, and carbon black is used to ensure the mixing effect of the mixture granular agent Molding effect.

[0027] 3) Mix antiaging agent 616 and antiaging agent 2246 through a jet mill to form solid powder.

[0028] 4) Put the mixture of solid powder and liquid through a rocking granulator, and dry it at a low temperature of 50-60°C to obtain the granule of the anti-aging agent. After rocking and mixing, the li...

Abstract

The invention discloses a latex anti-aging agent and a preparation method thereof, comprising the following components in parts by weight: 40-50 parts by weight of anti-aging agent SP, 20-30 parts by weight of anti-aging agent 616, and 25-25 parts by weight of anti-aging agent 30 parts by weight, 10-15 parts by weight of elastic carrier, 2-3 parts by weight of dispersant, 0.1-0.5 parts by weight of carbon black, wherein the ratio of parts by weight between anti-aging agent SP, anti-aging agent 616 and anti-aging agent 2246 is 4-5: 2-3: 2.5-3; the anti-aging agent used in the latex rubber products mixed with a variety of different anti-aging agents adopted by the present invention, through the synergistic effect between the anti-aging agents, the mixed The anti-aging agent has better practical effect than a single latex anti-aging agent in terms of heat resistance, UV resistance and pollution-free performance. The mixed anti-aging agent is fixed and formed after dewatering through the latex carrier, which is convenient for quantitative use and storage. .

Description

technical field [0001] The invention relates to the technical field of preparation of fine chemicals, in particular to a latex-type practical anti-aging agent and a preparation method thereof. Background technique [0002] Latex generally refers to the colloidal emulsion formed by dispersing polymer particles in water; the aqueous dispersion of rubber particles is customarily called latex, and the aqueous dispersion of resin particles is called emulsion; products made of latex as raw materials are called latex products , common such as sponges, gloves, toys, hoses, etc. [0003] There are many types of anti-aging agents and their functions are different. According to its main function, it can be divided into anti-thermal oxygen aging agent, anti-ozone agent, harmful metal ion inhibitor, anti-fatigue agent, ultraviolet absorber, anti-cracking agent, etc. There are many common rubber anti-aging agents used in latex products. Questions, such as: anti-aging agent 2245 has a co...
