Description

A kind of environment-friendly type aqueous encaustic tile coating and preparation method thereof

Technical field

The invention belongs to the chemical building material field, is a kind of environment-friendly encaustic tile coating and preparation method thereof specifically.

Background technology

Clay shingle is a kind of destruction to the soil environment, and the tile kilning that fetches earth is in a large number forbidden that by country cement tile is promoted the use of in all parts of the country, thereby a kind of new tiling protects and finishing material---encaustic tile coating also just arises at the historic moment.But on the market, the known encaustic tile coating of cement tile tiling that is used for both at home and abroad is based on oiliness acrylate encaustic tile coating at present, its market requirement grows on a steady double-digit, and oiliness encaustic tile coating product generally contains toluene, dimethylbenzene, acetone equal solvent, and its ratio is up to 40-50%.As everyone knows, toluene, dimethylbenzene all are toxic substance, these materials only play carrier function aborning, finally all evaporate in the atmosphere, obviously there is contaminate environment, the waste resource, shortcomings such as cost height, the four E targets (energy, environment, efficient, economy) of this and modern humans's Sustainable development are incompatible.

Summary of the invention

The purpose of this invention is to provide a kind of environment-friendly type aqueous encaustic tile coating free from environmental pollution and preparation method thereof, to overcome the problem that the oiliness encaustic tile coating exists.

To achieve these goals, proportioning raw materials of the present invention is:

Water 15-40 part dispersion agent 0.2-0.7 part foam control agent 0.1-0.2 part pigment 10-14 part

0.12 part in emulsion 40-60 part silicon sol 3-10 part film coalescence aid 1.5-2.5 part sterilant

Also can add in the said ratio wetting agent and (or) defoamer;

Above-mentioned dispersion agent can be a kind of preparation, also can be that several formulations is mixed;

Above-mentioned pigment can be a kind of pigment, also can be that multiple pigment mixes;

Above-mentioned film coalescence aid can be a kind of auxiliary agent, also can be that multiple auxiliary agent mixes;

Above-mentioned emulsion is benzene emulsion, pure-acrylic emulsion, organosilicon crylic acid latex.

Preparation method of the present invention is:

1. the water of getting umber ready, dispersion agent, foam control agent and pigment through high speed dispersion, grinding;

2. in the mixture after the 1. step, add emulsion, and slowly add silicon sol and mix;

3. mix at a slow speed after in the mixture after the 2. step, adding film coalescence aid and sterilant;

4. will be 3. the gained mixture after filtration, packing gets product.

Key of the present invention is to utilize organic and characteristics separately inorganics, silicon sol for example, and it is when drying out, and monomer silicic acid aggregates into poly silicic acid gradually, and along with the evaporation of moisture, the colloid molecule increases, and forms Si-o-Si at last and films.Because the particle diameter of silicon sol is trickle, is molecularity, thereby strong to basic unit's seepage force, tack is good, and its inorganic polymer coating itself just has advantage acidproof, alkaline-resisting, high temperature resistant, good endurance.Si-o-Si films and does not produce static simultaneously, is difficult for the absorption dust, and stain resistance is good.The polymer organic polymer is (as benzene emulsion, pure-acrylic emulsion, organosilicon crylic acid latex etc.) the physicals characteristics of filming are that the degradation property of UV resistant is good, coating gloss height after the film forming, cohesive strength is big etc., the science collocation of this organism and inorganics, organic polymer is evenly distributed in the gap of Si-o-Si inorganic coating, remaining hydrophilic radical and when temperature Change colds and heat succeed each other in the shielded inorganic coating, the contraction of the slow coating of speeding, make coating have certain elasticity, the advantage of two kinds of materials just shows especially out, thereby obtain high-quality end product---water-based encarpus tile coating, what must remind is, add man-hour, order and speed that material adds also have certain influence to quality product.

The quality of product of the present invention all meets or exceeds corresponding national standards (country does not formulate the technical quality standard of water-based encarpus tile lacquer as yet at present, now adopts the GB/T9755-1995 standard), and detected result is as follows:

Test item	Standard-required	Measured result
			Application property	It is accessible to brush two roads	It is accessible to brush two roads
Appearance of film	Appearance of film is normal	Appearance of film is normal
			Alkali resistance (48h)	No abnormal	No abnormal
Abrasion resistance (inferior)	500 times	Do not have for 500 times damaged, show-through
			Coating heatproof degree (10 circulations)	No abnormal	No abnormal

At the ubiquitous wasting of resources of present oiliness encaustic tile coating, environmental pollution, expensive three big shortcomings, technical characterictic of the present invention is as follows:

1, with water as solvent, its ratio is 26-40%, this with the oiliness encaustic tile coating in about 35% noxious solvent---toluene, dimethylbenzene are compared, not only save a large amount of precious resources, social benefit that it brings simultaneously and environmental benefit are conspicuous;

2, the 6 yuan/kg of product cost average out to (raw materials cost) that produces with the present invention, and the production cost average out to 8-10 unit/kg (raw materials cost) of oiliness encaustic tile coating, average low about 30%, thereby the market value of water-based encarpus tile coating on average also hangs down about 30%, practical and cheap product must have great commercial value;

3, since the present invention selected be nontoxic or basic poisonous material, its product is nontoxic, tasteless, it is not quick-fried not fire, and all is very useful concerning safe, the production of production environment and user of service's collectivity health.
