Embodiment 1

[0026] A kind of asphalt release agent, used for anti-sticking in asphalt mixture transportation and construction, comprises the following components in parts by weight: 6 parts of simethicone, 1.5 parts of fatty alcohol polyoxyethylene ether (AEO), 0.5 part Alkylphenol polyoxyethylene ether OP-10, 4 parts of glycerin, 80 parts of soybean oil, 40 parts of water, 0.6 parts of sodium benzoate, 0.3 parts of fragrance.

[0027] The preparation method is as follows: first heat each component to 60°C in advance, add simethicone, glycerol, and soybean oil into a reaction kettle at a constant temperature of 80°C in sequence, stir for 10 minutes, and then add fatty alcohol polyoxyethylene ether ( AEO), alkylphenol polyoxyethylene ether OP-10 and water, stirred for 20 minutes, then emulsified 3 times through a colloid mill at a speed of 6000r / min, and added preservatives and fragrances during the emulsification process. The asphalt release agent.

Embodiment 2

[0029] A kind of asphalt release agent, comprises following components by weight parts: 5 parts of simethicone oils, 1.5 parts of fatty alcohol polyoxyethylene ethers (AEO), 5 parts of glycerol, 70 parts of rapeseed oils, 35 parts of water , 0.6 parts of potassium sorbate, 0.2 parts of fragrance.

[0030] The preparation method is as follows: first heat each component to 70°C in advance, add simethicone oil, glycerol, and rapeseed oil into a constant temperature reaction kettle at 70°C in sequence, stir for 20 minutes, and then add fatty alcohol polyoxyethylene ether (AEO) and water, stirred for 15 minutes, and then passed through a colloid mill at a speed of 5000r / min for 3 times of high-speed shear emulsification to obtain the product, and the asphalt release agent was obtained by adding preservatives and fragrances during the emulsification process.

Embodiment 3

[0032] A kind of bitumen release agent, by weight, comprises the following components: 9 parts of simethicone, 1.8 parts of fatty acid methyl ester sulfonate (MES), 10 parts of glycerol, 80 parts of cottonseed oil, 60 parts of water, 0.8 parts sodium benzoate, 0.25 parts fragrance.

[0033] The preparation method is as follows: first preheat each component to 80°C, add dimethyl silicone oil, glycerol, and cottonseed oil in the order of 80°C constant temperature reaction kettle, stir for 15 minutes, and then add fatty acid methyl ester sulfonic acid Stir salt (MES) and water for 10 minutes, and then pass through a colloid mill for high-speed shear emulsification 3 times at a speed of 4000r / min. Add preservatives and fragrances during the emulsification process to obtain the asphalt release agent.

Abstract

The invention provides an asphalt separant and a preparation method thereof. The asphalt separant is uniform light yellow emulsion and comprises, by weight, 4-10 parts of dimethyl silicone, 1-2 parts of surface active agents, 4-10 parts of glycerol, 40-80 parts of plant oil, 20-60 parts of water, 0.5-0.8 part of preservative and 0.2-0.3 part of aromatic. The preparation method includes the following steps that all the components are pre-heated to 60-80 DEG C, the dimethyl silicone oil, the glycerol and the plant oil are sequentially added into a reaction kettle with the constant temperature of 60-80 DEG C, the surface active agents and the water are added after stirring is carried out for 10-20 min, then stirring is carried out for 10-20 min, high-speed shearing emulsifying are carried out for three times through a colloid mill at the rotation speed of 1000-6000 r / min, and the preservative and the aromatic are added in the emulsifying process, and the asphalt separant is prepared. The asphalt separant has the advantages of being environmentally friendly and free of pollution, and is soluble to water, good in chemical stability, excellent in high temperature and low temperature resistance, little in use amount and excellent isolation efficiency. Influences to performance of asphalt mixed materials are small, and the asphalt separant can be used for adhesion resistance of various mechanical devices in asphalt mixed material conveying and construction, and is wide in application range.

Description

technical field [0001] The invention belongs to the technical field of road materials, and in particular relates to an asphalt release agent and a preparation method thereof, which are used as an anti-adhesive asphalt release agent for various mechanical equipment in asphalt mixture transportation and construction. Background technique [0002] The release agent is a functional substance between the mold and the sample. It is used as an interface film layer on the surface of two objects that are easy to bond to each other. It is a type of processing aid that prevents the bond between the sample and the mold. As a material coated on the surface of the mold, the release agent has low surface energy, and can form a micron-level thick, thermally stable film on the surface of the mold, which can quickly and easily detach the molded sample, and the composition of the release agent has no effect on the sample. Less affected. [0003] During asphalt pavement construction, hot aspha...
