Problems solved by technology

However, almost all industrial solid cleaning agents contain weak acids such as sulfamic acid or citric acid and chelates, etc., and there is also serious pollution in their discharge environment
When in use, it can only be used for cleaning industrial equipment, and it cannot be used for heavy oil cleaning of daily utensils

Embodiment 1

[0034]Preparation of solid-liquid phase change heavy oil stain cleaning agent: the solid phase uses one part by weight of first-grade expanded perlite with a particle size of 60-80 mesh and an expansion factor greater than 20 times, and mixes and soaks with 5 parts by weight of the liquid phase for storage. The weight ratio of each component in the liquid phase is: CAB3%, AEO-92%, FMES2%, AOS2%, LAS1%, triethanolamine 1%, trisodium citrate 1%, 200ppm glycerin, 200ppm fruit acid and 100ppm orange essence , and the balance is water.

[0035] Heat 2 / 3 of the water in the raw material to 60°C, add surfactants AOS and AEO-9 under constant stirring to dissolve first, dissolve CAB with the remaining water and then add it, finally add FMES and LAS, and stir at a constant temperature of 60°C for 1 hour Finally, start to cool down to 40°C, then add triethanolamine, trisodium citrate, glycerin, fruit acid and orange essence, stir well and let it stand for 5 hours to make a solid-liquid p...

[0037] Preparation of solid-liquid phase change heavy oil stain cleaning agent: the solid phase uses one part by weight of first-grade expanded perlite with a particle size of 60-80 mesh and an expansion factor greater than 20 times, and mixes and soaks with 5 parts by weight of the liquid phase for storage. The weight ratio of each component in the liquid phase is: CAB2%, AEO-32%, FMES2%, AOS2%, LAS4%, triethanolamine 1%, trisodium citrate 1%, propylene glycol, beta glucan and fruit flavor each 100ppm, the balance is water.

[0038] Heat 2 / 3 of the water in the raw material to 60°C, add the surfactants AOS and AEO-3 under constant stirring to dissolve first, dissolve CAB with the remaining water and then add it, finally add FMES and LAS, and stir at a constant temperature of 60°C for 1 hour Finally, start to cool down to 40°C, then add triethanolamine, trisodium citrate, propylene glycol, β-glucan, and fruit essence, and make a solid-liquid phase change heavy oil dirt cleanin...

Embodiment 3

[0040] Preparation of solid-liquid phase change heavy oil stain cleaning agent: the solid phase uses one part by weight of first-grade expanded perlite with a particle size of 60-80 mesh and an expansion factor greater than 20 times, and mixes and soaks with 5 parts by weight of the liquid phase for storage. The weight ratio of each component in the liquid phase is: CAB5%, FMES2%, AOS2%, LAS5%, triethanolamine 1.5%, trisodium citrate 1.5%, each 150ppm of propylene glycol, beta glucan and fruit essence, surplus is water.

[0041] Heat 2 / 3 of the water in the raw material to 60°C, add the surfactant AOS under constant stirring to dissolve first, then add the CAB after dissolving the remaining water, and finally add FMES and LAS, stir at a constant temperature of 60°C for 1 hour, then start to cool down After reaching 40°C, add triethanolamine, trisodium citrate, propylene glycol, β-glucan and fruit essence, stir thoroughly and let it stand for 5 hours to make a solid-liquid phas...

Abstract

The invention discloses a solid-liquid phase change heavy oil dirt cleaning agent packaged by a porous medium and a preparation method thereof. The weight ratio of a solid phase of the cleaning agent to a liquid phase of the cleaning agent is 1:5; the solid phase is a first-level expanded perlite with the particle size of 60-80 mesh and the expansion times of more than 20 times; the liquid phase comprises 1-10 % by mass of an anionic surfactant, 1-10% by mass of an non-ionic surfactant, 1-3% by mass of triethanolamine, 1-3% by mass of trisodium citrate, a little amount of an auxiliary agent, and the balance being water. The anionic surfactant is a mixture of two or three of sodium alpha-olefin sulfonate, sodium dodecyl benzene sulfonate and fatty methyl ester sulfonate. The non-ionic surfactant is fatty alcohol-polyoxyethylene ether, cocamidopropyl betaine or a mixture thereof. The cleaning agent has both solid cleaning agent characteristics and liquid cleaning agent characteristics, is non-toxic, and has good biodegradability; and the preparation method has the advantages of simple operation and low cost, and has broad market prospects.

Description

technical field [0001] The invention relates to the cleaning agent field, a solid-liquid phase change heavy oil dirt cleaning agent encapsulated by a porous medium and a preparation method thereof. Background technique [0002] With the development of the economy and the improvement of people's living standards, the area of ​​ceramics and other solid-state appliances used in restaurants, hotels, stations, square docks, etc. in family life and public places has increased rapidly. It is very important to clean the hands and skin of workers in the repair industry after work, especially for some heavy dirt surfaces, because most of the oily dirt or stains on the surface are mixed oil stains, which are composed of engine oil, edible animals, etc. Vegetable oil and tiny dust floating in the environment and other small solid particles combine to form oil stains on the solid surface through sedimentation and physical or chemical action, which is one of the most troublesome problems ...
