CN1162487C - Antirust priming paint - Google Patents

Abstract

The present invention discloses antirust primer which contains 10 to 20 wt% of epoxy resin, 2 to 10 wt% of amino resin, 2 to 10 wt% of PVB resin, 0.5 to 3 wt% of phosphoric acid, 0.5 to 3 wt% of tannic acid, 10 to 20 wt% of aluminium tripolyphosphate, 10 to 20 wt% of glass scale, 10 to 15 wt% of micaceous iron oxide and 5 to 10 wt% of mica powder. The primer does not contain plumbum, chromium, cadmium or other heavy metal elements, so the primer has no harm to human bodies and does not generate pollution to the environment; steel surfaces with serious rust do not need to carry out rust removal, and the primer can be directly coated on the surfaces, so the present invention has the advantages of convenient construction and high adhesive force; the primer has high rust removing performance and good rust-proof corrosion-proof performance, and the primer has closed stable full efficiency of strong permeation and strong reactive conversion; the drying speed of the primer is high (the primer can be dried in ten minutes), and the primer can be solidified into films at normal temperature; the present invention has high elasticity, high hardness and good insulating property, and the present invention is resistant to shock, wear, water, (freshwater and seawater), moisture, heat (100 DEG C), weather, mould, acid, alkali and oil.

Description

Antirust priming paint

Technical field.

The present invention relates to a kind of ferrous metal rust proof paint.

Background technology.

At present, be used for the antirust rust proof paint in ferrous metal surface and contain heavy metal elements such as lead, chromium, cadmium mostly, human body there is harm, environment is also had pollution, must carry out processing of rust removing to the metallic surface before use, sticking power is not strong, come off easily, every not being swabbing again again how long, both increased maintenance cost, also make troubles to the user.

Summary of the invention.

The object of the present invention is to provide a kind of environment-friendly type antirust priming paint.

The objective of the invention is to realize by following approach: a kind of antirust priming paint, its component thing and weight percent are; Resins, epoxy 10-20%, aminoresin 2-10%, PVB resin 2-10%, phosphoric acid 0.5-3%, tannic acid 0.5-3%, aluminium triphosphate 10-20%, glass flake 10-20%, iron mica 10-15%, mica powder 5-10%.

The present invention has following advantage:

1: heavy metal element such as not leaded, chromium, cadmium to the human body toxicological harmless, does not produce pollution to environment yet;

2: the steel surface to serious corrosion need not carry out processing of rust removing, directly brushes easy construction;

3: the rust cleaning performance is strong, and the antirust, anti-corrosive performance is good, and rusty scale is had strong infiltration, and reaction transforms, and is stable, the all-round effect of sealing;

4: rate of drying fast (can refer in 10 minutes do), normal temperature be the energy film-forming down;

5: the elasticity height, hardness is big, and is shock-resistant, wear resisting property good;

6: water-fast (fresh water, seawater), moisture-proof, heat-resisting (can reach 100 ℃), weather-proof, anti-mould, acidproof, alkaline-resisting, oil resistant, good insulation preformance.

Embodiment.

Extracting epoxy resin 18Kg, aminoresin 9Kg, PVB resin 8Kg, phosphoric acid 2Kg, tannic acid 2Kg, aluminium triphosphate 19Kg, glass flake 19Kg, iron mica 14Kg, mica powder 9Kg, resin dissolves respectively, mixes then, adds the rust-inhibiting paint filler, fully stir evenly, grind, allocate, be made into the antirust priming paint of 100Kg.

Claims (1)

1. antirust priming paint, it is characterized in that: component thing and weight percent are; Resins, epoxy 10-20%, aminoresin 2-10%, PVB resin 2-10%, phosphoric acid 0.5-3%, tannic acid 0.5-3%, aluminium triphosphate 10-20%, glass flake 10-20%, iron mica 10-15%, mica powder 5-10%.
