Embodiment 1

[0013] The manufacture method-1 of the modified epoxy tie paint of the present invention. In the stainless steel barrel, first add 0.8 parts by weight of xylene, 0.2 parts by weight of n-butanol, and 0.4 parts by weight of cyclohexanone and mix evenly, then add 1 part by weight of epoxy resin to make it pre-dissolved, and then add 0.2 parts by weight of chlorine Ether resin, 0.2 parts by weight of chlorinated rubber, 0.2 parts by weight of acrylic resin, after high-speed stirring for 0.5h, add 0.6 parts by weight of wet-process sericite, 0.5 parts by weight of micaceous iron oxide, and 0.02 parts by weight of fumed silica while stirring , 0.6 parts by weight of talcum powder, 0.6 parts by weight of titanium dioxide, 0.02 parts by weight of polymethylalkylsiloxane solution, 0.01 parts by weight of polyamide wax, and then use a sand mill to circularly grind for 0.5 to 1 hour to obtain the modified chlorinated ether resin. Component A-1 of permanent epoxy link coating, 0.2 parts ...

Embodiment 2

[0015] The manufacture method-2 of the modified epoxy tie paint of the present invention. Mix the chloroether resin of 0.6 weight part in the same modified epoxy connection paint of embodiment 1, make modified epoxy connection paint A component-2.

[0016] The test results of the construction and coating adhesion of the modified epoxy connection coating are shown in Table 1.

[0017] Table 1

[0018]

[0019] The tin-free self-polishing antifouling paint and epoxy resin antirust primer are products of Tianjin Zhongyou Boxing Engineering Technology Co., Ltd., and the rest of the raw materials are commercially available.

Embodiment 3

[0021] 1 weight part epoxy resin is added in the mixed solvent of 0.8 weight part xylene, 0.2 weight part n-butanol, 0.4 weight part cyclohexanone, be dispersed and dissolved, then add 0.1 weight part chloroether resin, 0.1 weight part chlorine Rubber, 0.1 parts by weight acrylic resin, after high-speed stirring, add 0.4 parts by weight of wet-process sericite, 0.1 parts by weight of micaceous iron oxide, 0.01 parts by weight of fumed silica, 0.5 parts by weight of talcum powder, 0.5 parts by weight of Part titanium dioxide, 0.01 part by weight polymethyl alkyl siloxane solution, and then use a sand mill to grind 0.5h to make the coating A component; 0.01 part by weight cashew nut shell oil modified phenalkamine curing agent and 1 part by weight Parts of phenalkamine curing agent are mixed evenly to form component B of the coating.

Abstract

The invention relates to modified epoxy-connected paint and a preparing method thereof. An A component of the paint is prepared by adding epoxy resin into a mixed solvent of xylene, n-butanol and cyclohexanone, adding copolymer of vinyl chloride and vinyl isobutyl ether, chlorinated rubber, acrylic resin, wet-method sericite, mica iron oxide, fumed silica, talcum powder, titanium dioxide, a polymethylalkyl siloxane solution and polyamide wax, mixing, stirring, and grinding. A B component of the paint is prepared by mixing a cashew nut shell oil modified phenolic aldehyde amine curing agent and a phenolic aldehyde amine curing agent, and stirring uniformly. During using, the A component and the B component are mixed uniformly. The paint can be used for intermediate paint of anti-corrosive primer, and antifouling paint, or chlorinated rubber finish or decorative finish so as to ensure good adhesive force.

Description

technical field [0001] The invention relates to a modified epoxy connecting paint and a manufacturing method thereof, which are used for intermediate paints of antirust paints, antifouling paints or chlorinated rubber topcoats or decorative topcoats. Background technique [0002] The disadvantages of the existing epoxy resin intermediate paint are that the drying speed is slow, the construction period is long, and the scope of the top coat applicable thereto is narrow. Contents of the invention [0003] The purpose of the present invention is to provide a modified epoxy connection paint with fast drying speed, short construction period and good adhesion with various top paint coatings and its manufacturing method. [0004] A kind of modified epoxy connection paint according to the present invention is characterized in that 1 weight part epoxy resin, 0.8 weight part xylene, 0.2 weight part n-butanol, 0.4 weight part cyclohexanone, 0.01~0.8 weight part Chlorine ether resin,...
