Abstract

The invention relates to a water-based emulsified alcohol acid ready-mixed paint and a preparation technique thereof. The water-based emulsified alcohol acid ready-mixed paint comprises 32-50% of medium/long-oil alkyd resin, 2-5% of light calcium carbonate, 7-12% of pigment, 0.6-0.8% of emulsifier, 0.8-1.3% of cobalt, 1-3% of 801, 35-38% of water, 3-5% of 200# solvent oil and 2-3% of talcum powder. The preparation technique comprises the following steps: pouring the resin and 60% of solvent into a container, stirring while sequentially adding the pigment and all the filler and drying agent, and sufficiently stirring uniformly; and pumping into a horizontal sand mill by a feeding pump, milling to 40-45 meshes, pumping into the container, stirring for 20 minutes, adding the emulsifier and water, and thoroughly mixing all the raw materials until the viscosity is (Tu-4 cup viscometer) 80S. The ready-mixed paint is full and bright, and has the advantages of favorable yellowing resistance, high weather resistance, excellent wear resistance, excellent water resistance, excellent acid resistance, excellent salt resistance and favorable corrosion resistance.

Description

A kind of aqueous emulsifying alkyd ready-mixed paint and preparation technology thereof

Technical field

The present invention relates to a kind of novel aqueous emulsification alkyd ready-mixed paint, be mainly used in, in indoor wood or steel door and window, tables and chairs and relevant maintenance items, can directly coating on wooden bamboo structure, or directly coating metallic surface.

Background technology

Due to long-oil-length alkyd ready-mixed paint protective system in traditional solvent-borne type, organic volatile causes at paint application process taste very large too much during for indoor wooden bamboo or steel door and window, tables and chairs, environmental protection not, and the individual event aspects such as sticking power, acidproof, alkaline-resisting, salt tolerant, oil resistant, moisture resistance have one's own knack, and over-all properties all can't meet industrial needs.

Summary of the invention

In order to address the above problem, the objective of the invention is to propose long-oil-length alkyd ready-mixed paint protective system in a kind of-novel aqueous emulsification, the volatile matter that this product is filmed greatly reduces, physical and mechanical property is good, weathering resistance is strong, and there is excellent wear-resisting, water-fast, sour, salt and good corrodibility, the workability under indoor environment and preservative effect are had to gratifying test paper.

Technical scheme of the present invention is: a kind of aqueous emulsifying alkyd ready-mixed paint, the mass percent of each component is as follows:

Sequence number	Material name	Charging capacity (wt%)
			1	Middle long oil alkyd	32-50
2	The pigment powder	7-12
			3	Emulsifying agent	0.6-0.8
4	Fine particle calcium carbonate (800 order)	2-5
			5	Cobalt	0.8-1.3
6	Rare earth drier	1-3
			7	Water	35-38
8	Talcum powder (800 order)	2-3
			9	The 200# solvent oil	3-5

Another object of the present invention is to provide above-mentioned the preparation technology of aqueous emulsifying alkyd ready-mixed paint specifically comprises the following steps:

At first, add in container and start and stir accounting for 60% the 200# solvent oil of 3-5 wt% and middle long oil alkyd 32-50 wt%, add successively cobalt and the 1-3%801(rare earth drier of pigment powder 7-12 wt%, 800 purpose talcum powder 2-3wt%, 800 purpose fine particle calcium carbonate 2-5,0.8-1.3% in the process stirred) stir;

Secondly, by take away pump suction horizontal sand mill, ground, to be ground to the 40-45 order, the suction container stirs after 20 minutes and adds emulsifying agent 0.6-0.8wt%, water 35-38 wt% and remaining 200# solvent oil again, continue to stir, until fully mixing, all raw materials reach viscosity to (being coated with-4 glasss of viscosmeters) 80S, tinning discharging.

The invention has the beneficial effects as follows:

● there is excellent workability;

● greatly reduced the pollution of organic volatile to environment;

● remarkable water-repellancy and ageing-resistant performance;

● paint film is hard, has impact resistance, wear resistance and oil-proofness and solvent resistance widely;

● can support the use with most of high-performance rust-inhibiting paint and finish paint;

● basic unit's layer is had to good sticking power;

● there is superior construction property under multiple Atmospheric Condition..
