Abstract
The solventless epoxy resin coating is formed from main agent and solidifying agent, in which the composition of the main agent contains (wt%) epoxy resin 36%-39%, rutile-type titanium pigment 2.0%-4.0%, reaction-type diluent 4%-8%, defoaming agent 0.3%-0.5%, levelling agent 0.8%-1.0%, nonly phenol 4%-6%, colour powder 0.3%-1.5% and the rest is abrasion-resisting powder, and its solidifying agent contains 19%-24% of aliphatic amine (by using wt% of main agent as 100%. Said coating possesses strong adhesive force and mechanical strength.
Description
The present invention is relevant a kind of coating, especially a kind of epoxypaint of no-solvent type.
Resins, epoxy has strong adhesion, and physical strength height, and characteristics such as point insulating, chemical proofing be good are the comparatively ideal coating of a class.Along with developing rapidly of industries such as China's medicine, food, electronics, more and more high to the requirement of the environment cleanliness of its production plant.China's Code of design for ground surface and floor of buildings (GB50037-96) is 100 grades and ten thousand grades of dust proof workshop ground to air purity, all needs the mill floor cleaning wear-resisting, and the room air dustiness is low as far as possible, and is smooth, easy cleaning.This is not only the demand of improving working conditions, especially the assurance of quality product.The most frequently used in the wear-resisting clean terrace paint is epoxypaint, and this coating generally is divided into no-solvent type, solvent-borne type and water-soluble etc.Solvent-borne type generally can produce the volatilization of organic solvent, and this had both caused material damage, has polluted environment again, brings great harm for people's health.Water soluble paint is to make solvent with water, its compliance with environmental protection requirements, but exist that dope viscosity is less, shrink grading is big, solids content is low, one-pass film-forming is thin, and shortcoming such as easily wear no resistance after generation loose colour, the film forming during construction.
The purpose of this invention is to provide a kind of solventless epoxy resin coating.
The object of the present invention is achieved like this: solventless epoxy resin coating provided by the invention is made up of host and solidifying agent, and is specifically composed as follows: (weight %)
Host
Resins, epoxy 36%～39%
Rutile type Titanium Dioxide 2.0%～4.0%
Response type thinner 4%～8%
Defoamer 0.3%～0.5%
Flow agent 0.8%～1.0%
Nonyl phenol 4%～6%
Toner 0.3%～1.5%
The abrasion-resistant powder surplus
Solidifying agent
Aliphatic amide 19%～24% (is 100% in host weight %) wherein Resins, epoxy is a bisphenol A type epoxy resin; The response type thinner is glycidyl allyl ether, phenyl glycidyl ether; Defoamer is an ethylene-based polymer; Flow agent is an acrylic acid polymer; Toner is phthalocyanine blue C

The relevant components description of coating of the present invention is as follows:
Resins, epoxy---according to from the cleanly requirement of level ground coating of levelling, should have ambient cure, high cohesive force, strong physical strength, chemical proof, good electric property as the Resins, epoxy of film forming matter.
Solidifying agent---for from levelling level ground coating cleanly, reach and once construct into thickness, short-term is solidified the requirement that the back obtains high cohesive force, the selection of solidifying agent is a most principal work in the prescription, common solidifying agent can't meet the demands, and adopts modified firming agent, makes solidification process not have free ammonia and folds.
Thinner---from levelling cleanly level ground coating one-pass film-forming thickness reach 1-1.8mm, for preventing that the non-active solvent volatilization from producing paint film defect, selected reactive thinner for use, make nothing (volatilization) solvent based coating, simultaneously also meet environment protection requirement, improve execution conditions.
Auxiliary agent---from levelling cleanly level ground coating require high to the levelling property of filming, particularly under the thick film condition, should make the abundant levelling in the limited time of filming, require in the thick film bubble to discharge rapidly again and face does not stay defective, therefore, the selection of auxiliary agent such as flow agent, defoamer and consumption are the factors of crux very.On the one hand this type of auxiliary dosage increase can reduce the surface tension of filming, levelling that helps filming and froth breaking, and this analog assistant too much adds affiliation and causes and the bonding between resin, thinner and filler is had a negative impact immiscible thing on the other hand.It must be to guarantee fineness through dispersion grinding that multiple pigment, filler are arranged in this coating, improves dispersion efficiency, has also added dispersing auxiliary.
Toner---available pigment adds with work in-process pigment paste (slurry) form, guarantees that coating is uniformly dispersed and color and luster is attractive in appearance.
Abrasion-resistant powder---as filler, increase the wear resistance after the coating film forming, in addition, no matter from the still performance after the film forming of workability, the viscosity of coating is vital.Wish the solids content height of coating on the one hand, help self-leveling terrace coating like this and once obtain big thickness; Do not wish again that on the other hand viscosity is too high, unfavorable construction.Found through experiments, influence changes less the abrasion-resistant powder add-on to dope viscosity.For self-leveling floor coating, its maximum advantage just is that a construction area is big, integral seamless, and this just has higher requirements to the linear shrinkage of filming, and the add-on of abrasion-resistant powder can clearly reduce the linear shrinkage of filming, and improves the paint film quality.
The preparation method of solventless epoxy resin coating of the present invention is as follows: the preparation of (one) base-material liquid; (1) drop into Resins, epoxy, response type thinner, nonyl phenol by weight ratio successively in pill tank, under normal temperature, normal pressure, the back that stirs is stand-by; (2) preparation of coating (1) drops into abrasion-resistant powder, all outer raw materials of toner by weight ratio successively, in the process of feeding intake, to feed intake while stirring, or after casting a kind of raw material, drop into second kind of raw material after treating to stir basically again, the feed intake back that finishes disperseed 20～30 minutes with bottom gear (1200 ± 200 rev/mins) earlier with high speed dispersor, used top gear (2200 ± 200 rev/mins) to disperse again 15～25 minutes; (2) with the thing section that mixes by three-roller, grind 1-2 time, till fineness＜30 micron; (3) join the abrasion-resistant powder slurry: remaining base-material liquid, abrasion-resistant powder are poured in the pill tank after measuring according to prescription in will filling a prescription, mix with high speed dispersor, disperseed 15～25 minutes with bottom gear (1200 ± 200 rev/mins) earlier, use top gear (2200 ± 200 rev/mins) to disperse again 10～20 minutes; (4) material that mixes is passed through three-roller, grind one time on three-roller, grinding rate is controlled at 200 kilograms/hour; (5) color matching slurry: remaining base-material liquid, toner are according to pouring in the pill tank after measuring in will filling a prescription, mix with high speed dispersor, disperseed 20～30 minutes with bottom gear (1200 ± 200 rev/mins) earlier, use high gear (2200 ± 200 rev/mins) to disperse again 15～25 minutes; (6) with the mill base that mixes by three-roller, grind 2-3 time, till fineness＜20 micron; (7) (2) and (4) are poured into the accentization cylinder and mix, require slowly to add (6) according to colour atla then, with till colour atla is consistent, transfer viscosity at last until color; (8) sample thief send quality testing department to detect, be up to the standards can sieve, blowing.
Compared with prior art, the present invention has following advantage:
The response type thinner is adopted in the preparation of solventless epoxy resin coating of the present invention, has significantly reduced the pollution that brings because of solvent evaporates, and both compliance with environmental protection requirements had been saved energy consumption again, had reduced material damage, had brought tangible economic benefit and social benefit.
