Description
Technical field
The present invention relates to a kind of high abrasion-resistant environmental protection floor coating and production thereof, construction technology.
Background technology
Terrace is a kind of building materials that get into China in recent years, is mainly used in to lay ground.Terrace be applicable to some for health conditions requiring than higher place with require anti-impact to press the anticorrosive underground parking of looking like attrition resistantly, factory's storehouse (cross fork truck) etc.
Terrace paint can be divided into epoxy flooring coating, polyurethane floor coatings, vinylformic acid terrace paint (also being acrylic), vinyl floor coating and water-based terrace paint (aqueous epoxy resins) or the like by resin, and the most frequently used is epoxies.
The staple of epoxide terrace paint is epoxy resin and solidifying agent.Epoxide terrace paint can be divided into two kinds of solvent-borne type and no-solvent types; SOLVENT BASED EPOXY FLOOR COATINGS can be discharged a certain amount of volatile organic matter (VOC) in production, construction and solidification process; Cost is lower, but generally not environmental protection, the high amounts of solvents that exists in the system can have certain harm to human body; And the non-solvent epoxy terrace paint meets environmental protection concept, and the discharging of non-volatility organism is widely used in the covering with paint of modern industry terrace.But the no-solvent type terrace paint priming paint that uses at present, cohesive strength is little, and terrace paint is peeled easily, efflorescence, and wear resistance is not high, easy abrasion.
Summary of the invention
Deficiency to prior art; The invention provides a kind of high abrasion-resistant environmental protection floor coating and production thereof, construction technology; Adopt alumina in Nano level or nanometer grade silica as anti-wear agent; Select for use polyamines base acid amides or polymeric amide as solidifying agent, in order to solve problems such as the generally not environmental protection of present terrace paint, little, the easy decortication of cohesive strength, efflorescence, easy abrasion.
High abrasion-resistant environmental protection floor coating of the present invention comprises main raw material A, B component, the composition of each component and weight percent (%) as follows:
A component: epoxy resin: 55~80,
Reactive thinner: 1~15,
Anti-wear agent: 2~10,
Pigment: mill base 16~28,
Skimmer: 0.5~1,
Flow agent: 0.5~1,
Each component concentration sum is 100%;
B component: solidifying agent: 75~90,
Promotor: 5~10,
Anti-wear agent: 5~15;
Said A, B set of dispense ratio are 2: 1.
Measure its wear resistance (750g/500R) with the wear resistant instrument of filming, the present invention adopts alumina in Nano level or nanometer grade silica as anti-wear agent, and the wear weight loss amount of terrace paint is 0.013 gram, far below standard GB/T1768-1979 wear weight loss amount 0.040 gram.The wear resistance of high abrasion-resistant environmental protection floor coating of the present invention is greatly improved, and wear resistance is three times of common terrace paint.
The bond strength of tradition solidifying agent is 1.1Mpa; And solidifying agent of the present invention is different from traditional T13 type and aliphatic cyclic amine family solidifying agent; Select for use polyamines base acid amides or polymeric amide as solidifying agent, solidifying agent bond strength surpass 4.4Mpa, terrace paint is peeled easily, the atomizing problem thereby solved.
Adopt the low molecular weight liquid epoxy of bisphenol A-type among the present invention; Compare with the used resin of general terrace paint; It has following characteristics: (1) is thermoplastic resin; But have thermoset, can form multiple performance excellent in curing thing, almost can satisfy various request for utilizations with multiple solidifying agent, catalyzer and additive.(2) good manufacturability of resin.Basically do not produce the small molecules volatile matter during curing, but low pressure molding.(3) cured article has very high intensity and bonding strength.(4) cured article has higher erosion resistance and electrical property.(5) cured article has certain toughness and thermotolerance.
A component formula of the present invention also contains reactive thinner (like C12-C14 glycidyl ether, propenoate glycidyl ether), skimmer (BYK066), flow agent (BYK354), pigment materials such as (mill bases), and the system that makes has good preservation stability, plasticity-and good construction performance preferably.
B component formula of the present invention contains solidifying agent (like polyamines base amide hardener, polyamide curing agent), promotor (mixing K54 epoxy promotor), anti-wear agent (like alumina in Nano level, nanometer grade silica).B component formula and A component formula proportional mixing form high abrasion-resistant environmental protection floor coating, possess the water-repellancy priming paint of moist solidified performance, and can become the anti-soil and the protective material of concrete surface.
The preparation method of high abrasion-resistant environmental protection floor coating; It is characterized in that: the A component: weigh by proportion of composing in the prescription A component, epoxy resin, reactive thinner, skimmer are dropped into the dispersion cylinder successively, disperseed 15 minutes with 1000-1500 rev/min; Add anti-wear agent, flow agent again; And 500-800 rev/min disperse 15-30 after, add mill base and be mixed to designated color, filter and package; B component: weigh by proportion of composing in the prescription B component, the B component is dropped into the dispersion cylinder successively, pack after 15 minutes with 1000-1500 rev/min of dispersion.
The invention has the beneficial effects as follows: (1) superpower wear-resistant property is three times that common terrace coats with lacquer, and increases by three times work-ing life; (2) outstanding adhesion is three times of traditional terrace priming paint, is particularly suitable for away fork truck; (3) have water-repellancy, can on flush, reach underwater curing; (4) has the oil-resisting performance of anti-soil; (5) solvent-free, environmental protection, and reach environment-friendly type terrace coating standard.Thereby can solve that current terrace paint is peeled easily, atomizing common fault and not environmental protection, wear resistance are not high, the problem of easy abrasion etc.
