Problems solved by technology

Most single products are not functional enough to meet actual application requirements
Compared with single products, the performance of compound products has been significantly improved, but many compound products can only focus on a certain function at present, such as low-foaming cleaning surfactants have poor cleaning effect and difficult to remove oil stains; high-efficiency cleaning surfactants The agent also has the problem of excessive foaming, which requires multiple rinses, complicated operation, and waste of water resources; in addition, many products on the market cannot achieve low-temperature decontamination, and require medium-high temperature conditions to achieve the effect, increasing energy consumption and cost

Abstract

The invention discloses a functional cleaning surfactant and a preparation method thereof. The functional cleaning surfactant is prepared from the following raw materials in parts by mass: 45 to 65 parts of fatty alcohol ether, 15 to 25 parts of fatty alcohol polyoxyethylene ether, 10 to 20 parts of block polyether, and 5 to 20 parts of fatty alcohol polyoxyethylene ether carboxylate, wherein a structural formula of fatty alcohol ether is RO(C3H6O)m(C2H4O)nH or RO(C2H4O)m(C3H6O)mH; R is selected from at least two types of branched paraffin in the range of C8 to C14; m is an integer in the range of 1 to 8; n is an integer in the range of 5 to 30. The functional cleaning surfactant has the advantages that the dirt removal ability is good, the content of foams is low, the rinsing is easy, thelow-temperature cleaning effect is better, the usage amount is less, the cost is low, the technology is simple, the green and environment-friendly effects are realized, the pollution is avoided, andthe functional cleaning surfactant is suitable for daily chemical cleaning and various cleaning industries.

Description

technical field [0001] The invention relates to the technical field of surfactants, in particular to a functional cleaning surfactant and a preparation method thereof. Background technique [0002] Surfactants are widely used and play a very important role in the cleaning industry. At present, there are many types of surfactants for cleaning on the market, including single products and compound products. Most single products are not functional enough to meet practical application requirements. Compared with single products, the performance of compound products has been significantly improved, but many compound products can only focus on a certain function at present, such as low-foaming cleaning surfactants have poor cleaning effect and difficult to remove oil stains; high-efficiency cleaning surfactants The agent also has the problem of excessive foaming, requires multiple rinses, complicated operation, and waste of water resources; in addition, many products on the marke...
