Description
Technical field
The present invention relates to a kind of functional building coating, particularly a kind of antiseptic and antistatic terrace paint and preparation method thereof.
Background technology
At present, antistatic floor coatings can be divided into two classes, and a class is an oil paint, and another kind of is water-borne coatings.Major part contains the benzene series thinner in the oil paint, has toxicity, contaminate environment, harm humans health.Along with people's environmental consciousness improves, many countries have issued restriction volatile organic solvent (VOC) environmental regulation, so coating hydrotropismsization direction develops into inevitable.In recent years, water-base epoxy product performance newly developed have had very big improvement, can satisfy the performance requriements of people to product, therefore, the coating development of water-base epoxy series has obtained development faster, but the functional product kind is less in the existing water-base epoxy coating series, and function singleness, cost are higher, antistatic property remains further to be improved.
Summary of the invention
Technical problem to be solved by this invention is, at the deficiencies in the prior art, provides a kind of function complete, antibiotic and antistatic effect is good, cost is low, be beneficial to environmental protection, antiseptic and antistatic terrace paint that the mechanical property of filming is high.
The present invention solves its technical problem and solves by following technical solution:
Antiseptic and antistatic terrace paint comprises first, second two components, and the composition and the weight percent of each component are as follows:
The first component:
Aqueous epoxy curing agent 26～36
Defoamer 0.2～0.6
Wetting agent 0.2～0.6
Flow agent 0.3～0.8
Freedom from cracking agent 1～2
Filler 25～53
Pigment 0～12
Mill base 0～6
Water 8～24
The second component:
Aqueous epoxy resin emulsion 76～94
Antibiotic antistatic agent 2～6
Water 4～20
First, second components by weight is 1: 1～1: 1.3.
Described antibiotic antistatic agent is poly-ether of cellulose quaternary ammonium salt (another name: JR-400).JR-400 is a kind of cationic fiber resin, for white or yellowish particle powder, can disperse and be dissolved in water rapidly.Cell walls and cytolemma are made up of phospholipid bilayer, and be electronegative under neutrallty condition, and therefore, bacterium is attracted by the JR-400 positively charged ion easily, thereby reduce the mobility of bacterium, suppresses its respiratory function, cell wall rupture, and content oozes out and death.In addition, bacterium is under the gravitational effect of electric field, and the negative charge skewness on cell walls and the cytolemma causes distortion, physical property takes place break, and makes outside the interior foul such as permeable mass such as water, protein of cell, " bacteriolyze " phenomenon takes place and death.The sterilization of JR-400 cationic fiber resin, has a broad antifungal spectrum can not produce resistance, and be without any side effects to the human body high safety, not influenced by High Temperature High Pressure, purplish red outside line irradiation.The physics electric field that the JR-400 cation group produces, the static of adsorption zone negative charge leaks static charge rapidly, produces antistatic effect.
Described aqueous epoxy curing agent is polyamine-epoxy polymer.Polyamine-epoxy adduct can stand high speed dispersion, grinding, and inorganic and pigment dyestuff are had wetting dissemination, need not add dispersion agent when abrasive inorganic pigment.
Described aqueous epoxy resin emulsion, its activeconstituents is a bisphenol A type epoxy resin, and it is high and the not hydroxyl of facile hydrolysis and ehter bond have good sticking power to multiple base materials such as concrete to contain polarity in the molecule, volumetric shrinkage during paint solidification is low, and chemical resistant properties is good.And bisphenol A epoxide resin is the structure that inflexible phenyl ring and flexible ehter bond are alternately arranged, give filmed mechanical property and permeability preferably, when being used with aqueous epoxy curing agent, have remarkable alkali-resistivity, filming of being become has good hardness and chemical resistant properties.
The used filler of the present invention is low oil absorption ferric, stable performance, 1000～1500 orders, alkalescence or inert filler.As: ground barium sulfate, talcum powder, heavy barium carbonate etc.Add the cost that suitable filler can not only reduce terrace paint, shorten the surface drying time of filming, can also improve physical strength, wear resistance, gloss and the opacifying power of filming, and give the coating good storage stability.
Pigment that the present invention adopts is chemical resistance and weathering resistance mineral dye preferably.
Mill base of the present invention is an aqueous color paste.
Use the freedom from cracking agent to be natural fat wax derivative among the present invention, to improve the resistance to cracking that terrace is filmed.Because terrace is filmed when drying process and difference variation, terrace film coated surface convergent force can change, and the freedom from cracking agent can improve the early stage tensile strength of terrace film coated surface effectively, thereby has solved the terrace be full of cracks problem of filming.
Also used wetting agent among the present invention, to improve wettability; Add flow agent, improved the levelling property of coating, relatively poor because the surface tension of water is higher to the wettability of ground, add wetting agent and improve its wettability, improved the levelling property of coating simultaneously.Because the existence of amine hardener has reduced surface tension and easy entrapped air problem, so also added defoamer, defoamer can form slick flat surface simultaneously when the aqueous epoxy floor coating application.
The preparation method of antiseptic and antistatic terrace paint of the present invention is:
First component: earlier a part of water of formula ratio, whole defoamer, wetting agent and color stuffing are put into dispersion cup, high speed dispersion, reduce to low speed then, adding waterborne curing agent and remainder water middling speed again mixes, then adding all the other auxiliary agents and mill base disperses, become mixed solution again through grinding, filter, packing.
The second component: water, antibiotic antistatic agent and the part aqueous epoxy resin emulsion of formula ratio are put into dispersion cup, and low speed disperses, and adds the aqueous epoxy resin emulsion low speed dispersing and mixing of surplus again, filters, packs.
Before using, the second component is added the first component, stir, and leave standstill and activate, and be coated with within a certain period of time with finishing, can add suitable water and carry out viscosity adjustment, can brush after stirring.Behind the overtime, masking liquid condenses into glue, loses flowability, and can not construct.
Terrace paint of the present invention is a kind of novel functional terrace coating, antibiotic, anti-static effect is good, lasting, do not contain solvent, no volatile matter (VOC) discharging has the ideal feature of environmental protection; Adjustment pigment is formed, and can obtain the multicolour effect, and is ornamental strong; That aqueous epoxy resins is filmed is nonflammable, water-fast, oil resistant is dirty, the chemicals-resistant corrosion, and good permeability, smooth bright and clean, has the favorable mechanical physicals, and cost is lower, applied widely, can satisfy the reload request that is coated with of modern industry, civilian and commercial terrace, be a kind of terrace paint that has a extensive future.
