Abstract
The invention relates to an acrylic acid mixed powder coating, which is characterized in that the formula comprises the following components in pbw (part by weight): 25 to 40 portions of epoxy resin, 25 to 40 portions of acrylic acid resin, 0.5 to 2 portions of leveling agent, 30 to 35 portions of filler, 0.1 to 0.2 portion of system catalyst, and 0.1 to 2 portions of other additive. The acrylic acid mixed powder coating has the advantages of lower costs, simple preparation and production, no need for curing agent, better hardness, excellent chemical and pollution resistance, long outdoor endurance, and broad application prospects.
Description
Technical field
The present invention relates to a kind of acroleic acid mixed powder coating.
Background technology
Typical powder coating mostly is Resins, epoxy-alkyd resin system, and wherein, the carboxylic functionality of vibrin is about 3～4, and hardness is not high, and because a large amount of ester groups that contain in the polyester are subject to the influence from the hydrolysis reaction of common pollutant.And, have the aromatic component of certain content in Resins, epoxy-alkyd resin system, influenced the yellowing resistance and the anti-loss of gloss of its outdoor exposure.In addition, need to add isocyanate curing agent in the existing acroleic acid mixed powder coating and be cured, and isocyanates material severe toxicity does not meet current environmental protection requirement.
Summary of the invention
The objective of the invention is to overcome above-mentioned defective, provide a kind of without solidifying agent, cost is lower, has preferable hardness,, the acroleic acid mixed powder coating of good chemical-resistant and resistance to crocking and higher outside durabitity.
The present invention can realize by following scheme: a kind of acroleic acid mixed powder coating, it is characterized in that its prescription is by weight: 25～40 parts of Resins, epoxy, 25～40 parts of acrylic resins, 0.5～2 part of flow agent, 30～35 parts of fillers, 0.1～0.2 part of System Catalyst, 0.1～2 part of other auxiliary agent.
Wherein, described filler is a Rutile type Titanium Dioxide; Described System Catalyst is the silica supports that is loaded with 70wt% 2-propyl imidazole; Described Resins, epoxy is the bisphenol A type epoxy resin of equivalent 500～1000, functionality 2; Described acrylic resin is equivalent 700～780, functionality 5-6, carboxylic acid functional group's a acrylic resin.
The carboxylic functionality 5～6 of the acrylic resin of acroleic acid mixed powder coating of the present invention, and the typical mixed type carboxylic functionality about 3～4 of vibrin.The functionality of system is high more, and the hardness of general gained is high more.Different with vibrin, acrylic resin does not contain a large amount of ester groups, thereby is not subject to the influence from the hydrolysis reaction of common pollutant.In addition, higher functionality can make acroleic acid mixed system more soluble.Propenoic acid main chain is made of the C-C main chain in the acroleic acid mixed powder coating, and the molecular chain flexibility is bigger, and intermolecular tap density is bigger, and yellowing resistance and anti-loss of gloss are preferable.
As preferably, the Resins, epoxy of acroleic acid mixed powder coating of the present invention and acrylic resin match by 1: 1 equivalent.
By above-mentioned prescription, the preparation method of acroleic acid mixed powder coating of the present invention is: form accurate weighing material by prescription, placed the high-speed mixer mixing 10-12 minute; Extrude under 100-115 ℃ temperature with forcing machine after the mixing of materials; It is that median size is the powder particle of 35-45 micron that extruded stock is pulverized with pulverizer; Powder particle sieves with 140 eye mesh screens, is packaged as finished product.
Acroleic acid mixed powder coating of the present invention has following advantage: 1. improved outside durabitity with respect to epoxy-vibrin system, hardness is better; 2. the yellowing resistance and the anti-loss of gloss of its outdoor exposure have been improved; 3. more excellent resistance to crocking; 4.Need not to add in addition solidifying agent, cost is lower.
Embodiment
Further specify the present invention below by embodiment.
Form accurate weighing material by table 1 Example formulations, placed the high-speed mixer mixing 10-12 minute; Extrude under 100-115 ℃ temperature with forcing machine after the mixing of materials; It is that median size is the powder particle of 35-45 micron that extruded stock is pulverized with pulverizer; Powder particle sieves with 140 eye mesh screens, is packaged as finished product.
The prescription of acroleic acid mixed powder coating is as shown in table 1:
The prescription of table 1 acroleic acid mixed powder coating (weight part)
Press the foregoing description gained acroleic acid mixed powder coating, adopt electrostatic gun spraying 50-70 μ m, solidified 25 minutes at 190 ℃ of Electric heat ovens.Coating is carried out service check.Its main film performance is:
The film performance of table 2 acroleic acid mixed powder coating
| Test result: | 1 | 2 | 3 |
| 60 ° of gloss | 94％ | 93％ | 68％ |
| Square impact | 50KG.CM | 50KG.CM | 50KG.CM |
| Pencil hardness | 5H | 5H | 5H |
| Anti-methylethylketone (two-way wiping examination number) | P100 | P100 | P100 |
| Planeness (PCI standard) | 5～6 | 6～7 | 7 |
| Salt mist experiment 2000 hours | 1 grade | 1 grade | 1 grade |
Its ageing resistance also improves than the powder coating of epoxy-polyester system in addition.
Above embodiment is to the explanation of patent and further explains, rather than limitation of the present invention, and in spirit of the present invention and rights protection scope, any modification of being made all falls into protection scope of the present invention.
