The invention also provides a use method of the coating for nylon base material. The coating for nylon base material has the advantages of simplified construction process and strong adhesion.
Description
Technical field
The present invention relates to a kind of coating and using method thereof, especially a kind of coating and using method thereof that is used for nylon base.
Background technology
Nylon is a kind of engineering plastics with good physics and chemical property, of many uses, but because its degree of crystallinity height, force of cohesion are big, the bonding strength of general coating on nylon base is less, thereby makes general coating be difficult to be attached directly to the surface of nylon base; And, when adopting existing coating on nylon base, to be coated with, generally need earlier nylon base to be carried out surface treatment, feel secure with epoxy coating then, be coated with polyurethane finish at last, so construction technology is comparatively numerous and diverse, therefore causes construction cost height, efficient low easily, and then is difficult to satisfy the demand in market.
Summary of the invention
In view of above-mentioned condition, be necessary to provide a kind of construction technology and stronger coating for nylon base material and using method thereof of bonding strength simplified.
A kind of coating for nylon base material comprises first composition and second composition.In the gross weight of coating, first composition comprises 45～55% Hydroxylated acrylic resin, 10～20% pigment, 5～10% N-BUTYL ACETATE, 5～10% 1-Methoxy-2-propyl acetate, 1～2% promotor and is less than or equal to 0.5% auxiliary agent; Second composition comprises 10～20% isocyanate curing agent.
A kind of using method of coating for nylon base material, it may further comprise the steps: first composition of compo and second composition, wherein in the gross weight of coating, first composition comprises 45～55% Hydroxylated acrylic resin, 10～20% pigment, 5～10% N-BUTYL ACETATE, 5～10% 1-Methoxy-2-propyl acetate, 1～2% promotor and is less than or equal to 0.5% auxiliary agent, and second composition comprises 10～20% isocyanate curing agent; Add thinner in the mixture of first composition and second composition, be adjusted to working viscosity with the viscosity with coating, wherein thinner comprises N-BUTYL ACETATE, toluene, dimethylbenzene and 1-Methoxy-2-propyl acetate; Coating is applied on the nylon base; And it is coating material solidified on nylon base.
The construction process of above-mentioned coating for nylon base material is comparatively simple, and when coating nylon base, is easy to generate stronger bonding strength, can guarantee that therefore above-mentioned coating for nylon base material and nylon base can mortise.
Embodiment
Below in conjunction with embodiment coating for nylon base material of the present invention and using method thereof are described in further detail.
A kind of coating for nylon base material of embodiment of the present invention, it comprises first composition and second composition.Gross weight in this coating, first composition can comprise 45～55% Hydroxylated acrylic resin, 10～20% pigment, 5～10% N-BUTYL ACETATE, 5～10% 1-Methoxy-2-propyl acetate, 1～2% promotor and be less than or equal to 0.5% auxiliary agent, and second composition can comprise 10～20% isocyanate curing agent.Wherein the solids content of Hydroxylated acrylic resin can be 55%, and viscosity can be 4500～6000cps/30 ℃, and acid value can be 3～5mgKOH/g, and second-order transition temperature can be 47 ℃; Promotor can be adhesion promoter; And auxiliary agent can be flow agent.
Need to prove, in first composition, the content of Hydroxylated acrylic resin can be preferably 48～52%, the content of pigment can be preferably 11～15%, the content of N-BUTYL ACETATE can be preferably 7～10%, the content of 1-Methoxy-2-propyl acetate can be preferably 5～8%, and the content of promotor can be preferably 1.2～1.8%; In second composition, the content of isocyanate curing agent can be preferably 17～20%.
The coating for nylon base material of embodiment of the present invention in use, normally earlier first composition and second composition are mixed, and then the adding thinner is adjusted to working viscosity with the viscosity with this coating in the mixture of first composition and second composition, then this coating is applied on the nylon base, coating material solidified on nylon base at last.Wherein, thinner can comprise N-BUTYL ACETATE, toluene, dimethylbenzene and 1-Methoxy-2-propyl acetate, and in the gross weight of this thinner, thinner can comprise 40% N-BUTYL ACETATE, 20% toluene, 20% dimethylbenzene and 20% 1-Methoxy-2-propyl acetate; The method of coating can be spraying or showering; In addition, solidification process can carry out at normal temperatures, certainly, for accelerating curing speed, also can adopt heating, and catalysis is quickened to solidify.
The construction process of above-mentioned coating for nylon base material need not steps such as pre-treatment, so construction process is comparatively simple; And when coating different nylon bases, be easy to generate stronger bonding strength, therefore can guarantee above-mentioned coating and nylon base mortise.In addition, above-mentioned coating for nylon base material in use, and is more or less freely to the allotment of pigment, therefore is easy to make coating to present different colors or gloss, and then satisfies different outward appearance needs, promotes decorate properties; And above-mentioned coating for nylon base material also can have preferable weathering resistance.
Especially, have stronger bonding strength, below will enumerate specific embodiment and be described further for proving above-mentioned coating for nylon base material.
The present invention tests three groups of coating for nylon base material prescriptions, and these three groups of coating for nylon base material prescriptions are as shown in table 1 below; Test process is to carry out with reference to international standard ISO2409-2007, and employed equipment comprises that paint film draws the 600# adhesive tape of lattice device, 3M company, and test result is as shown in table 2.
