Problems solved by technology

The existing antirust coatings for springs are prone to flash corrosion, and cannot be reused, which not only wastes resources, but also increases the cost of use; at the same time, there is a phosphating process in the use of antirust coatings, which will generate phosphating waste pollute the environment

preparation example Construction

[0018] figure 1 It is the process step diagram of the antirust emulsion preparation method used for spring in the embodiment of the present invention; The preparation method comprises the following steps: a) preparing phosphate monomer, b) preparing epoxy acrylate monomer, c) preparing pre-emulsion, and d) preparing polymer emulsion.

[0019] The antirust emulsion used for springs mentioned in the present invention uses methyl methacrylate and butyl acrylate as comonomers, uses self-made epoxy acrylate monomers as functional monomers, and introduces self-made anti-flash corrosion Phosphate monomer, prepared by pre-emulsification process and semi-continuous seed polymerization method. Among them, the epoxy acrylate monomer can increase the crosslinking degree of the polymer emulsion, improve the compactness of the coating film formed by the antirust emulsion on the surface of the spring, and enhance the adhesion and salt water resistance of the coating film. Phosphate ester m...

Embodiment

[0021] The specific preparation method is as follows:

[0022] a) Preparation of phosphate monomer, the specific preparation process is as follows: firstly weigh 55% of hydroxyethyl acrylate, 12% of hydroquinone, and 33% of phosphorus pentoxide; Put the ester and hydroquinone in a stirring container, stir and mix in a water bath at 70°C, then slowly add phosphorus pentoxide, heat to 80°C after mixing, and perform esterification for 3 hours; then add a certain amount of deionized water to hydrolyze After 2h, the material is discharged, and the phosphoric ester monomer is obtained.

[0023] b) Preparation of epoxy acrylate monomer, the specific preparation process is: first weigh 44% of epoxy resin E-51, 52% of acrylic acid, and 4% of methyl methacrylate by weight percentage; Resin E-51 and acrylic acid were mixed in a stirring container, and added to react in a water bath at 98°C for 1.5 hours; then methyl methacrylate was added, mixed and reacted for 0.5 hours, and the materi...

Abstract

The invention provides a rust-proof emulsion for a spring and a preparation method thereof. The rust-proof emulsion is prepared from methyl methacrylate, butyl acrylate, a phosphate monomer, an epoxyacrylate monomer, an emulsifying agent and deionized water. The preparation method comprises the following steps: a) preparing the phosphate monomer; b) preparing the epoxy acrylate monomer; c) preparing a pre-emulsion; d) preparing a polymer emulsion. The invention discloses the rust-proof emulsion for the spring and the preparation method thereof. The rust-proof emulsion is prepared by using a pre-emulsification process and a semi-continuous seed polymerization method, the obtained rust-proof emulsion not only has an excellent salt-spray corrosion resistance, but also is recyclable, and waste liquid cannot be generated to pollute the environment.

Description

technical field [0001] The invention relates to an antirust emulsion, in particular to an antirust emulsion used for springs and a preparation method thereof, belonging to the technical field of springs. Background technique [0002] A spring is a mechanical part that uses elasticity to work. As an important component in an industrial system, it has a large amount of use and a wide variety. Although the spring industry is a small industry in the entire manufacturing industry, its role is very important. The country's industrial manufacturing and automobile industries need to accelerate development, and the spring industry, as one of the basic parts and components, needs to have an advanced stage of development in order to adapt to the rapid development of the country's entire industry. In addition, the expansion of the scale and variety of spring products and the improvement of the quality level are also the needs of the replacement of mechanical equipment and the improveme...
