Abstract
The invention discloses a washing rust remover which comprises the following components in parts by weight: 20-30 parts of 85wt% phosphoric acid, 10-15 parts of naphthenic acid, 2-5 parts of triethanolamine, 0.15-0.30 part of diethylenetriamine, 10-15 parts of ammonium bicarbonate, 0.5-0.8 part of sodium chlorate, 60-70 parts of water, 8-12 parts of aluminum naphthenate, 5-8 parts of sodium alkyl benzene sulfonate and 10-15 parts of sodium tripolyphosphate. The invention also provides a preparation method of the washing rust remover. The washing rust remover prepared by the method provided by the invention can be used for simultaneously finishing washing, phosphorous removal, rust removal, corrosion resistance and rust resistance of a black metal surface by just one step, so that lots of steps are reduced in treatment of the black metal surface, and thus a black metal surface basal body is prevented from peracid, and the preparation method is simple, convenient, wide in material sources and capable of greatly improving the effects and increasing the yield and the rate of finished products.
Description
Technical field
The present invention relates to chemical field, relate to particularly a kind of cleaning rust remover for ferrous metal surface.
Background technology
Ferrous metal refers to iron, manganese, chromium and alloy thereof, if the ferrous metal such as steel, the pig iron, iron alloy, cast iron are after cleaning, for preventing surface corrosion, must carry out antirust processing, for example, apply rust-preventive agent on surface.In prior art, early use the good slushing oil of rust-proof effect, form protective oil film by slushing oil in metallic surface, isolated water in air vapour is to corrosion of metal, thereby it is antirust to reach the long period.But, use slushing oil not only to need to consume a large amount of oil plant raw materials, aggravate energy consumption, and in the time of following process, also need further to clean and go on a tour, not only produce the discharge that contains in a large number waste liquid, cause environmental pollution, it is time-consuming that second phase is cleaned oil removing, increase cost, therefore, can complete cleaning, dephosphorization, rust cleaning, anticorrosion and antirust in the rust remover of one in the urgent need to a kind of simultaneously.
