Abstract

The invention relates to water-soluble paint, specifically provides a water-soluble paint for a railway export wagon, and aims at solving the problem that the current water-soluble paint does not meet the requirement of export wagons. The water-soluble paint is prepared by mixing a component A and a component B based on the ratio of 4: 1, wherein the component A comprises the following raw materials in parts by weight: 60 parts of waterborne acrylic modified polyurethane resin, 0.5 part of dispersing agent, 0.35 part of wetting agent, 0.15 part of defoamer, 0.1 part of neutralizer, 15 parts of titanium dioxide pigment, 12 parts of talcum powder, 0.2 part of thickening agent, 10 parts of rust preventing agent, and 1.7 parts of water; the component B serving as a crosslinking curing agent is water-based isocyanate. According to the water-soluble paint, all the performances meet or exceed the current standard on oil paint for export wagons; the water-soluble paint can be applied to the other fields, besides railway export wagon.

Description

Railway export truck vehicle water soluble paint
Technical field
The present invention relates to water soluble paint, be specially a kind of railway export truck vehicle water soluble paint.
Background technology
Overall application lacquer painting is wanted, for anticorrosion, antirust, the UV resistance (ageing-resistant) of truck vehicle in goods train vehicle surface.At present, outlet lorry vehicle paintwork uses oil-base paint (chlorinated rubber protective system), and VOC content is high, toxicity is large, contaminate environment, infringement HUMAN HEALTH, prohibits the use the truck vehicle of the various model of oil-base paint application abroad.Foreign trader requires higher to the performance index of water soluble paint, and existing water soluble paint cannot meet the demands.Also there is no the water soluble paint that can reach outlet lorry vehicle needs at present.
Summary of the invention
The present invention solves the problem also not having the water soluble paint that can reach outlet lorry vehicle needs at present, provides a kind of railway export truck vehicle water soluble paint.
The present invention adopts following technical scheme to realize: railway export truck vehicle water soluble paint, is formed by 4:1 allotment by first component and component B; First component is made up of the raw material of following weight part: aqueous acrylic modified urethane resin 60; Dispersion agent 0.5; Wetting agent 0.35; Defoamer 0.15; Neutralizing agent 0.1; Pigment titanium white 15; Talcum powder 12; Thickening material 0.2; Rust-preventive agent 10; Water 1.7; Component B adopts water-based polyisocyanates as crosslinking and curing agent.
The preparation method of railway export truck vehicle water soluble paint adopts following steps to realize:
The preparation of first component:
1) aqueous acrylic modified urethane resin, dispersion agent, wetting agent, defoamer, neutralizing agent adds in scuffing of cylinder bore in described ratio, low rate mixing 10-15 minute, add face again and fill out titanium white, talcum powder, rust-preventive agent uniform stirring 10-15 minute, add water, high-speed stirring about 30 minutes, obtain just batch mixing;
2) first batch mixing sand mill is ground, require temperature out less than 40 DEG C, below fineness 30um, obtain thin batch mixing;
3) thin batch mixing is squeezed into join in paint still add thickening material and carry out joining paint, be adjusted to suitable viscosity (rotational viscosimeter 1.5MPa);
4) discharging, filters with 80 order nets, obtains first component;
Paint:
First component and component B are mixed in the ratio of 4:1, obtains the finished product.
Railway export truck vehicle water soluble paint of the present invention has good sticking power, hardness and snappiness, and has very high weather resistance, more than artificial accelerated aging test 1000h.The innovation essence producing the technical scheme of these technique effects is preferred, the optimization of component and proportioning.On component is selected, the present invention has selected two component, is namely main film forming matter with aqueous acrylic modified urethane resin, with water-based polyisocyanates for solidifying agent, and simultaneously preferred auxiliary material, and optimize the proportioning of each material component.Preferred and the optimization of component and proportioning just creates the technique effect of the performance index being obviously better than existing water paint just.Technical solution of the present invention be by a large amount of tests and the financial resources of at substantial, material resources, manpower obtain, process of the test is a creationary process inherently.
Railway export truck vehicle water soluble paint of the present invention adjusts spray viscosity with deionized water when using, and then spraying detects model; Defects liability period: by detection perform requirement, traditional performance test panel is deposited, and (normal room temperature is done solid work rear) was detected after 10 days.Type inspection, inspection in dry latter 14 days (detecting after moisture content is fully volatilized).Detect through product quality supervision and inspection central vehicle test house of the Ministry of Railways, its detected result is in table 1:
Table 1: water-soluble antifouling paint detected result
Water-soluble antifouling paint and chlorinated rubber protective system performance index contrast table:
As can be seen from the table, the superiority of performance, especially VOC content and resistance to artificial climate accelerated deterioration, give prominence to very much, and in addition, the performance chlorinated rubber protective system such as heat-resisting, impact, cupping does not possess.Properties all can meet or exceed the oil-base paint standard on existing outlet truck vehicle.
Railway export truck vehicle water soluble paint of the present invention, except being exclusively used in railway export lorry, also can be used for other field.
Embodiment
Railway export truck vehicle water soluble paint, is formed by 4:1 allotment by first component and component B; First component is made up of the raw material of following weight part: aqueous acrylic modified urethane resin 60; Dispersion agent 0.5; Wetting agent 0.35; Defoamer 0.15; Neutralizing agent 0.1; Pigment titanium white 15; Talcum powder 12; Thickening material 0.2; Rust-preventive agent 10; Water 1.7; Component B adopts water-based polyisocyanates as crosslinking and curing agent.
The preparation method of railway export truck vehicle water soluble paint adopts following steps to realize:
