Abstract

The invention discloses a modified silanized metal surface pre-treating agent containing octylphenol polyoxyethylene ether. The pre-treating agent is prepared from the following raw material components in parts by weight: 100 parts of de-ionized water, 10-15 parts of modified coupling agent, 10-15 parts of propyl alcohol, 30-40 parts of silane coupling agent 791, 20-30 parts of silane coupling agent KH-570, 0.001-0.003 part of sodium perfluorooctane sulfonate, 0.3-0.5 part of tree ash, 4-6 parts of polyvinyl acetate emulsion, 2-3 parts of urea, 0.4-1.0 part of phenylethylphenol polyoxyethylene ether, 0.2-0.8 part of octylphenol polyoxyethylene ether, 0.005-0.01 part of lanthanum nitrate, and 0.1-0.3 part of phytic acid. By adopting coupling agent modification and compounding, and adding auxiliary agents, the mixture reacts to obtain the end product. The modified silanized metal surface pre-treating agent has the characteristics of being non-toxic, environment-friendly, and convenient to use; and a silane film is compact, uniform, large in adhesive force and good in corrosion resistance.

Description

technical field [0001] The invention relates to metal surface treatment agent technology, in particular to a modified silylated metal surface pretreatment agent containing octylphenol polyoxyethylene ether and a preparation method thereof. Background technique [0002] Corrosion of metal materials occurs around us every moment. According to statistics, about 10% of metal materials are corroded and cannot be recycled every year. This not only causes a huge waste of metal resources, but also poses a serious threat to normal production and personal safety. Surface treatment of metal materials is a commonly used anti-corrosion method. Method, the main method currently used for metal coating pretreatment is phosphating method. However, the traditional metal surface treatment methods have problems such as pollution to the environment due to the presence of toxic and harmful substances, and are no longer suitable for the increasingly high environmental requirements of human societ...
