Abstract
The invention discloses an epoxy resin powder paint which mainly contains 50-80 parts of bisphenol A epoxy resin (A) and bisphenol A epoxy resin (B), 10-30 parts of flaky inorganic filler, 5-10 parts of plasticizer and 2-5 parts of curing agent. The epoxy resin powder paint has favorable heat resistance and weather resistance, and can be widely used in coatings on automobiles, ships, buildings and the like.
Description
Technical field
The invention belongs to high-molecular coating field, particularly a kind of epoxy powder coating.
Background technology
Powder coating is form diverse with general coating, and it exists with the state of fines.Owing to not using solvent, so be called powder coating.Powder coating manufactures due to the synthetic resins that the molecular weight ratio that is insoluble to solvent or water under can using normal temperature is larger, thus can obtain finer and close film, and compared with liquid film, powder coat is more sturdy and durable; Compared with liquid film, do not need the adjustment carrying out viscosity, easily realize automatization, greatly improve coating efficiency, save cost; Meanwhile, owing to not using any solvent, low VOC, greatly reduces the pollution to environment.Due to good adhesive capacity, and acid and alkali-resistance, intensity high, maximum with epoxy powder coating volume of production and marketing again in powder coating, the epoxy powder coating output of Shi Jie various countries has all exceeded 50% of powder coating total amount, has more been above 60% in China.And the most frequently used in epoxy powder coating be bisphenol A type epoxy resin powder coating, account for more than 90% of epoxy powder coating, but due to its molecule epoxy group comparatively small amt, curing cross-linked density is low, and containing ehter bond in resin, easily degrade after solar UV irradiates, thus make its fragility larger, thermotolerance is poor, and weathering resistance is bad.
Summary of the invention
In order to improve thermotolerance, the weathering resistance of epoxy powder coating, the invention provides the scheme of the epoxy resin solids powder coating of following technical scheme:
1. an epoxy powder coating, is characterized in that this coating contains following component: 1) 50-80 part bisphenol A epoxide resin (A) and bis-phenol (A) epoxy resin (B); 2) 10-30 part flaky inorganic filler; 3) 5-10 part softening agent; 4) solidifying agent 2-5 part.
2. the epoxy powder coating as described in aforementioned 1, wherein, described part bisphenol A epoxide resin (A) is between oxirane value 0.1-0.15, and bisphenol A epoxide resin (B) is between oxirane value 0.02-0.05.
3. as described in aforementioned 2 epoxy powder coating, wherein, bisphenol A epoxide resin (A) and bis-phenol (A) epoxy resin (B) weight ratio are 1:2.
4. the epoxy powder coating as described in aforementioned 1, wherein, described mineral filler is talcum powder with silane coupling agent process or mica.
The invention provides a kind of epoxy powder coating, the thermotolerance of this epoxy powder coating and good weatherability, the coatings such as automobile, boats and ships, building can be widely used in.
Embodiment
According to the present invention, epoxy powder coating of the present invention, main containing following component: 1) 50-80 part bisphenol A epoxide resin (A) and bis-phenol (A) epoxy resin (B); 2) 10-30 part flaky inorganic filler; 3) 5-10 part softening agent; 4) solidifying agent 2-5 part.
In order to the thermotolerance that obtains and weathering resistance, wherein, described part bisphenol A epoxide resin (A) is preferably the bisphenol A epoxide resin between oxirane value 0.1-0.15, and bisphenol A epoxide resin (B) is preferably the bisphenol A epoxide resin between oxirane value 0.02-0.05.And the weight ratio of bisphenol A epoxide resin (A) and bisphenol A epoxide resin (B) is preferably between 1:3-1:1, more preferably 1:2; Mineral filler is wherein preferably talcum powder or mica, further the preferred talcum powder through silane coupling agent process and mica.
Solidifying agent can be acid anhydride type curing agent, also can be amine curing agent, but is preferably amine curing agent, more preferably Dyhard RU 100, and in order to improve consistency and the reactive behavior of solidifying agent and epoxy resin, Dyhard RU 100 is preferably through the Dyhard RU 100 of substituting modification.Softening agent is preferably polyamide wax, polyethylene wax and Zinic stearas, more preferably polyamide wax; Meanwhile, epoxy powder coating of the present invention can also add the pigment such as ferric oxide, carbon black or titanium dioxide; The various usual auxiliaries such as flow agent, defoamer or photostabilizer.
Epoxy powder coating of the present invention can use conventional dry method or wet processing to be prepared, and is preferable over dry process preparation
Below in conjunction with specific embodiment technical scheme of the present invention done and illustrate further.
Embodiment
First by 20 parts of micas 200 DEG C of thermal treatments 1 hour, then 0.2 part of KH550 silica coupling agent blending and modifying is added, then the mica of this modification is joined 20 parts of bisphenol A epoxide resin E-14 with 40 parts of bisphenol A epoxide resin E-03 mixing bisphenol A epoxide resins, add 5 parts of polyamide waxes and 3 parts of Dyhard RU 100 SA284; Then said mixture homogenizer is mixed 10 minutes, then melt extrude after compressing tablet shatters with forcing machine and sieve.
