Description
Technical Field
The invention relates to the technical field of marking paint for sports grounds, in particular to non-yellowing and high-adhesion environment-friendly marking paint.
Background
The special marking paint for the sports ground is subjected to sun and rain, wind and snow, freezing and impact abrasion of soles, white marking lines can fade or become yellow rapidly along with the passage of time, and if a resin and solvent system is selected improperly or the viscosity is not controlled properly, the special marking paint for the sports ground has the defects of biting the soles, burrs and the like.
At present, the commonly used marking paint is mostly prepared by taking thermoplastic acrylic resin as a base material and adding pigment, filler, auxiliary agent and solvent. The solvent is mostly toxic solvent such as xylene. In addition, some of the marking paints show a relatively large difference in the adhesion effect to various substrates, with the self-grained surface paints of the plastic track being the most difficult to adhere.
Therefore, the environment-friendly marking paint which is not yellowed and has excellent bonding force has great market value.
Disclosure of Invention
In order to overcome the defects of the prior art, the invention provides the non-yellowing and high-adhesion environment-friendly marking paint which is non-yellowing and does not fade rapidly along with the time lapse or rain erosion; excellent adhesion and is suitable for various base materials; the solvent is an environment-friendly solvent, and the harm to the body is reduced.
The technical scheme of the invention is as follows: the non-yellowing and high-adhesion environment-friendly marking paint comprises the following components in percentage by mass: 1, a component A and a component B;
wherein the component A comprises the following components in parts by weight: 20-50 parts of base material, 20-40 parts of titanium dioxide, 0.2-1 part of dispersing agent, 0.01-0.5 part of catalyst and 20-40 parts of solvent;
the component B is a curing agent; 10-30 parts.
Preferably, the non-yellowing and high-adhesion environment-friendly marking paint comprises a component A and a component B in a mass ratio of 5: 1;
wherein the component A comprises the following components in parts by weight: 45 parts of base material, 30 parts of titanium dioxide, 0.5 part of dispersing agent, 0.02 part of catalyst and 24.5 parts of solvent; the component B is a curing agent; and 20 parts.
The binder is selected from a mixture of hydroxyl acrylic resin, alkyd resin and polyurethane resin; wherein the polyurethane resin comprises polyether polyurethane resin and polyester polyurethane resin.
Wherein the hydroxyl acrylic resin has a low hydroxyl value of less than or equal to 70 and TG of less than or equal to 20 ℃. Hydroxyl is an active functional group used for post-crosslinking on an acrylic resin side chain, and the distribution of-OH on a main chain has very important influence on the performance of a paint film. The other main function of the-OH groups is to increase the polarity of the hydroxy acrylic resin, improve the adhesion and the wet dispersibility of the paint film. Therefore, the amount of the-OH groups has great influence on the crosslinking density of the coating and the chemical and mechanical properties of a paint film. However, too many-OH groups are required, and curing agents are required, which increases the cost of the curing agents. The hydroxyl acrylic resin has a low hydroxyl value of less than or equal to 70, can meet the requirement of crosslinking, and is favorable for improving the adhesive force and wetting dispersibility of a paint film.
The hydroxyl value of the alkyd resin is 100-150, so that the marking paint is resistant to yellowing and hydrolysis. The paint prepared by using the alkyd resin as a base material has lower surface tension ratio and is less influenced by the defects of a coating film, and the problems of edge shrinkage, shrinkage cavity and other defects caused by surface tension driven flow or surface tension difference driven flow are avoided. In addition, the alkyd resin is not flocculated in a solvent, the material is easy to disperse, the alkyd resin has the capability of crosslinking through automatic oxidation, and air drying or low-temperature baking drying can be adopted, so that the crosslinking agent with potential toxicity hazards is avoided being used for drying.
The polyurethane resin includes polyether polyurethane resin and polyester polyurethane resin. The polyether polyurethane resin has hydrolysis resistance, high strength, good rebound resilience and good low-temperature performance. The polyester type polyurethane resin has good tensile property, flexibility, wear resistance, solvent resistance and high temperature resistance. The difference of the two performances is mainly caused by the difference of the two molecular compositions, wherein the adhesion force of the ester group in the polyester polyurethane resin and the polar base material is stronger than that of the polyether polyurethane resin, and the hydrolysis resistance of the polyether polyurethane resin is stronger because the hydrolysis-resistant ester group which is relatively easy to hydrolyze does not exist. The marking paint and the water-based paint are mixed for use, so that the marking paint has excellent adhesion and hydrolysis resistance and is durable in use.
The titanium dioxide is used as pigment and mainly plays a role in whitening and increasing the covering power in the marking paint.
The dispersing agent is alkylhydroxy ammonium salt of a block copolymer object containing an acidic group, preferably BYK-180, and mainly has the effects of dispersing pigment and filler, reducing viscosity, and improving the stability problems of sedimentation, caking and the like in the storage process. The catalyst is dibutyltin dilaurate.
The solvent is selected from one or a mixture of more of methyl ester, ethyl ester, butyl ester or propylene glycol methyl ether acetate (PMA).
The curing agent is Hexamethylene Diisocyanate (HDI) dimer, such as Bayer N75.
The non-yellowing and high-adhesion environment-friendly marking paint disclosed by the application has the beneficial effects that the components play a synergistic role, wherein the hydroxyl acrylic resin is used as a base material, the crosslinking degree is good, and the adhesive force and the wetting dispersibility of a paint film are excellent. The alkyd resin is selected to endow the marking paint with yellowing resistance and hydrolysis resistance, and the phenomena of edge shrinkage and hole shrinkage are avoided. The polyurethane resin is selected to endow the marking paint with excellent bonding force and hydrolysis resistance, and is durable in use. The solvent is one or a mixture of more of refined methyl ester, ethyl ester, butyl ester and propylene glycol monomethyl ether acetate (PMA), is nontoxic and noncorrosive, is an environment-friendly solvent, and reduces the harm to the body. The curing agent selects Hexamethylene Diisocyanate (HDI) dimer for fast curing time, can be cured quickly at normal temperature, selects titanium dioxide as pigment, has strong covering power and good whitening performance, and can avoid yellowing phenomenon. The marking paint is suitable for bonding on the surfaces of various base materials, has good bonding force, and cannot be eroded and rapidly faded along with wind, rain and rain.
