Abstract

The invention designs a preparation method of an antirust agent and particularly relates to a preparation method of a methyl silicate aqueous nano antirust agent. The antirust agent is prepared from the following steps: preparing a nano methyl silicate homogenate by using nano methyl silicate and a 731A dispersing agent; and mixing and dispersing the nano methyl silicate homogenate, acrylic resin, DPnB, dibutyl phthalate, a thickener, a silicon sol, propylene glycol and water 500 to prepare the methyl silicate aqueous nano antirust agent. According to the methyl silicate aqueous nano antirust agent provided by the invention, the raw material methyl silicate is an inorganic/organic composite material which is prepared from silsesquioxane which is a byproduct methyl trichlorosilane hydrolysate in production of organic silicon, so that the raw material is low in price and easily available; the antirust agent is free of toxicity and pollution, has hydrophilic and lyophobic performances and relatively strong acid and alkali resistance and is an excellent water-based antirust additive.

Description

The preparation method of methyl silicate water nano rust-preventive agent
Technical field
The present invention designs a kind of preparation method of rust-preventive agent, is specially the preparation method of methyl silicate water nano rust-preventive agent.
Technical background
The corrosion of metal is the problem often run in producing, and the iron and steel that the whole world is scrapped because getting rusty every year reaches several ten million tons, causes serious financial loss.At present, steel product is sealed up for safekeeping for a long time and antirust is adopted slushing oil more, but subsequent handling need carry out oil removal treatment, and oil is not easily decomposed, and removes some difficulty, and there is the problem of environmental pollution that discharging of waste liquid brings.Along with the growing tension of petroleum resources and the continuous enhancing of environmental protection protective awareness, the research of water-based antirust is made to be subject to extensive concern both domestic and external.
At present, the passivating technique of water-based antirust many employings nitrite and chromic salt, the product that with the addition of nitrite and chromic salt has the obvious advantages such as inexpensive, respond well and easy to use, research shows, the body material of this series products is one indirectly carcinogenic substance, has severe toxicity, serious environment pollution, using and discharging of it is all subject to strict restriction, and thus, the Research Significance not containing the water-based antirust of nitrite is great.In recent years, the composite rust-preventive agent, polyol ester rust-preventive agent and the metallic surface self-assembly rust-preventive agent based on organism etc. of thanomin and acid some study, but majority can only be used for rust prevention during manufacture, slushing oil can be replaced as sealing antirust water-based antirust almost not the having of widespread use aborning long term up for safekeeping.
Summary of the invention
For above-mentioned technical problem, the invention provides a kind of nontoxic water-based antirust, concrete technical scheme is:
The preparation method of methyl silicate water nano rust-preventive agent, comprises the following steps:
(1) preparation of nanometer methyl siliconic acid zinc homogenizing fluid:
Following raw material mixes according to parts by weight, nanometer methyl silicate 90-110 part, water 500-700 part, 731A dispersion agent 18-20 part; Mixed raw material carries out good pressure distribution process by clarifixator with the flow velocity of the pressure of 50 MPas and 500 liters per hour, obtained nanometer methyl silicate homogenizing fluid;
(2) preparation of water nano rust-preventive agent:
Following raw material is prepared according to parts by weight: nanometer methyl silicate homogenizing fluid 80-100 part, acrylic resin 300-350 part, DPnB25-30 part, dibutyl phthalate 15-20 part, thickening material 0.2-0.5 part, silicon sol 10-15 part, propylene glycol 10-20 part, 500 parts, water mix, and turns/min rotating speed emulsion dispersion 30 minutes by emulsification shears with 600-800; Both methyl silicate water nano rust-preventive agent was obtained.
Described nanometer methyl silicate is nanometer methyl siliconic acid zinc or nanometer methyl siliconic acid aluminium.
Described 731A dispersion agent is polyacrylic acid sodium salt waterborne pigment dispersant.
Described DPnB is dipropylene glycol n-butyl ether.
By metal products, the mode of spraying or soaking can be directly taked to carry out antirust operation.Because zinc in methyl silicate or aluminium can be combined with coordination mode by the carboxyl of ACRYLIC EMULSION in coating, point to metal end in the coating.After rustproof layer solidification, methyl is distributed in coatingsurface outwardly, plays repulsive interaction to water or damp atmosphere, improves solidity to corrosion and the weathering resistance of coating.Again due to high dispersion and the lower bulk density of methyl silicate, highly stable water-based antirust agent can be made with ACRYLIC EMULSION etc.
Methyl silicate water nano rust-preventive agent provided by the invention, prepared using methyl silicate be during organosilicon is produced byproduct METHYL TRICHLORO SILANE hydrolysate silsesquioxane obtained inorganic/organic composite material, cheap and easy to get, nontoxic pollution-free, having hydrophilic, hydrophobic performance and stronger acidproof, alkali resistance, is a kind of aqueous rustproof additive of excellence.
