5 parts of mica powders
10 parts of high light barium
5 parts of special sanitass
The B component is to be processed by the raw material of following parts by weight:
10 parts of modified amine curing agents
Glass reinforced plastic of the present invention is with special modified solvent free epoxy coating, and said A, the ratio when two kinds of components of B are mixed are the A component: B component=100: 19～23.
Glass reinforced plastic of the present invention is with special modified solvent free epoxy coating; The process step of preparation A component is: each raw material in the A component is good by above-mentioned prescription weighing, and low speed adds in the dispersion machine successively, and makes its blending dispersion even; Be warming up to 60 ± 5 ℃ again; Kept temperature 20 minutes, it is qualified to grind up to fineness then, can lead to cold water or steam maintenance temperature at this process sand mill.
Glass reinforced plastic of the present invention uses the beneficial effect of the special solventless epoxy coating of modification to be: 1, these article do not contain solvent, and solid 100% belongs to non-toxic, environmental friendly coating.2, the present invention is made up of A, B two components; Two component proportional mixing during use can react curing rapidly, and metal or non-metallic substrate are had extremely excellent cohesive force, stopping property, good mechanical mechanics property; Resistance to compression, shock resistance, shear strength height have superior corrosion resistance.3, can effectively shield various media,, have very high antikathode stripping performance simultaneously like the infiltration of acid, alkali, salt, water, solvent.4, thick being coated with property is good, and one time coating thickness can reach 200～1000 μ m.5, can be in constructing in the environment more than 0～5 ℃, the scope that conforms is big.6, can spray, brushing, roller coat, easy construction is workable, coating quality is controlled.
Embodiment
Be described further with special modified solvent free epoxy coating in the face of glass reinforced plastic of the present invention down.
With special modified solvent free epoxy coating, this coating is formed by A, two kinds of component proportional mixing of B glass reinforced plastic of the present invention with LDF-20A glass reinforced plastic:
Wherein: the A component is to be processed by the raw material of following parts by weight:
60 parts of epoxy resin
4 parts of reactive thinners
3.5 parts of anti-settling agents
0.5 part of dispersion agent
0.5 part of flow agent
0.5 part of skimmer
1 part of silane coupling agent
5 parts of mica powders
10 parts of high light barium
5 parts of special sanitass
The B component is to be processed by the raw material of following parts by weight:
10 parts of modified amine curing agents
LDF-20A glass reinforced plastic of the present invention is with special modified solvent free epoxy coating, and A, the ratio when two kinds of components of B are mixed are the A component: B component=100: 19～23.
LDF-20A glass reinforced plastic of the present invention is used the modified solvent free epoxy coating; The process step of preparation A component is: each raw material in the A component is good by above-mentioned prescription weighing, and low speed adds in the dispersion machine successively, and makes its blending dispersion even; Be warming up to 60 ± 5 ℃ again; Kept temperature 20 minutes, it is qualified to grind up to fineness then, can lead to cold water or steam maintenance temperature at this process sand mill.
LDF-20A glass reinforced plastic adaptable across metal or nonmetal anticorrosion engineering, is the liquid protective system of a kind of novel nontoxic, two component with special modified solvent free epoxy coating.Confirm that through practice test LDF-20A glass reinforced plastic has has met or exceeded the level of external like product with the performance of special modified solvent free epoxy coating.
Table 1 LDF-20A glass reinforced plastic is with special modified solvent free epoxy coating performance index
Table 2 LDF-20A glass reinforced plastic is with special modified solvent free epoxy coating coating performance
LDF-20A glass reinforced plastic of the present invention is following with the constructional method of special modified solvent free epoxy coating:
Batching: A: B=100: 20
After during use stirring two component proportional mixing, can apply immediately, not need slaking.The consumption of solidifying agent can suitably adjustment in the scope of regulation according to envrionment temperature, humidity.
LDF-20A glass reinforced plastic of the present invention is with the coating consumption of special modified solvent free epoxy coating:
This coating is coated with special construction technology and combines with three no glass wool cloths, forms HS, high performance glass reinforced plastic corrosion protection coating.Coating branch regular grade, add three kinds of intensity level and Te Jia intensity levels.Regular grade is a cloth three oil (putting three layers of oil of one deck cloth brush), build 650 ± 50 μ m, and the coating consumption is 1.5kg/m
2Adding intensity level is two cloth, four oil (putting four layers of oil of two layers of cloth brush), build 950 ± 50 μ m, and the coating consumption is 2kg/m
2It is three cloth, five oil (putting five layers of oil of three layers of cloth brush) that the spy adds intensity level, build 1250 ± 50 μ m, and the coating consumption is 2.6kg/m
2The additional special-purpose solvent or diluent that 30～80kg is provided per ton is exclusively used in and cleans coating tool and equipment, and this solvent or diluent is forbidden to add in the coating, in order to avoid influence coating performance.
LDF-20A glass reinforced plastic of the present invention is following with the coating construction step of special modified solvent free epoxy coating:
1, surface treatment: remove welding slag, the burr of substrate surface, the derusting by sandblast grade reaches the Sa2.5 level of GB9823 regulation.
