Problems solved by technology

Obviously, a single brand of petroleum wax cannot meet the technical requirements for the chemical composition of rubber protective wax, so it is usually necessary to use different manufacturers and brands of petroleum wax for deployment when preparing rubber protective wax. Affected by various factors such as technical parameters of the production process, such as dewaxing and deoiling, the chemical composition of petroleum wax often fluctuates greatly, resulting in different quality of protective wax products, which has great impact on raw material procurement and formulation determination. There are many troubles. The frosting of protective wax is a problem that the formulators are more concerned about. The natural aging verification is time-consuming and labor-intensive. At present, the rubber tire industry has no relatively uniform test method for verifying rubber frosting. Therefore, tire product manufacturers urgently need a A quick and convenient method for evaluating the performance of protective wax and frost

preparation example Construction

[0040] The preparation method of above-mentioned formula sizing material, step is as follows:

[0041] In the open mill, the above-mentioned matrix rubber is firstly mixed evenly, and the color, active agent and vulcanization / accelerator are added in turn to knead evenly, and the above-mentioned protective wax test formula rubber is obtained.

[0042] The present invention also discloses a method for quickly evaluating the protective wax spit cream by using the above formula, which includes the following steps:

[0043] Step 1: Cut the protective wax test compound that needs to be tested for frosting into a sample of a specified size, stick cellophane on both sides and place it on a flat vulcanizing machine for vulcanization;

[0044] Step 2: Remove the cellophane from the vulcanized sample, and place it in an oven at 80°C for 3 minutes to 5 minutes to make the appearance color uniform;

[0045] Step 3: After taking dust-proof measures for the above-mentioned samples, place t...

Embodiment 2

[0067] In Example 2, each formula was only placed for 24 hours, and the obvious phenomenon of frosting can be observed, and the result of frosting rate is protective wax A > protective wax B > protective wax C, which is consistent with the theory;

[0068] To sum up: the combination of the test formula of the protective wax and the evaluation method of the present invention can quickly and accurately evaluate the frost of the raw material protective wax.

Abstract

The invention discloses a formula for quickly releasing frost from protective wax, a preparation method of the formula and a method for quickly evaluating frost from protective wax, and relates to the technical field of manufacturing rubber products. The present invention combines the experimental formulation of the protective wax and the evaluation method, which can shorten the process of protective wax emerging from the formula. The effect that usually takes several months can be achieved by the present invention within 24 hours, which can be quickly and accurately Evaluating the frosting of raw material protective wax will help rubber product manufacturers to control the quality of protective wax raw materials, and facilitate the purchase of protective wax and formula development in rubber factories. The materials and process required for the formula of the protective wax to quickly release frost of the present invention are simpler and easier to operate than the conventional evaluation formula, and can shorten the process of the protective wax emerging from the rubber. The evaluation method of the present invention can measure the rate of frost discharge relatively quickly and accurately.

Description

【Technical field】 [0001] The invention relates to the technical field of manufacturing rubber products, in particular to a formula for rapid frosting of protective wax in the field of tire manufacturing, a formula preparation method and a method for rapidly evaluating frosting of protective wax. 【Background technique】 [0002] During the processing, storage and use of rubber products, it is inevitable that they will be subjected to the combined effects of physical and chemical factors such as heat, light, ozone, radiation, mechanical force, etc., which will cause the unsaturated double bonds in the rubber to break or crosslink, and then make Aging phenomena such as degradation of mechanical properties (hardening, stickiness and brittleness) or cracking of rubber products occur, among which ozone is the main factor causing rubber aging. [0003] In order to make rubber products durable, the industry mainly adopts the method of adding a certain proportion of protective wax to ...
