Embodiment 1

[0031] The low-toxic flame-retardant marking line primer of this embodiment is based on parts by weight. The main raw materials are: 320 parts of acrylic resin, 30 parts of dioctyl phthalate, and A and B two-component solvent, among them,

[0032] The formula of component A by weight is: 320 parts of dichloromethane, 20.4 parts of isopropanol or tert-butanol;

[0033] The formula of component B in parts by weight is: 5 parts of butyl acetate, 5 parts of acetone, and 216 parts of aromatic hydrocarbons. The preparation method of the low-toxic flame-retardant marking line primer of the present embodiment comprises the following steps:

[0034] (1) Put the component A solvent into the reactor by weight, stir for 15 minutes, add the corresponding weight of acrylic resin or styrene-modified acrylic resin, and keep the speed of the reactor at 50-120 rpm until the resin is completely dissolve;

[0035] (2) In the slurry prepared in step (1), put the component B solvent into the rea...

Abstract

The invention discloses a low-toxicity flame-retardant double-component marked line coating agent and a preparation method thereof. The marked line coating agent is mainly prepared from the followingraw materials in parts by weight: 320 parts of acrylic resin or styrene modified acrylic resin, 30 parts of plasticizer and a solvent with components A and B, wherein the component A is prepared fromthe following components in parts by weight: 320-330 parts of chlorinated hydrocarbons and 20.4-28.7 parts of low-grade saturated monohydric alcohol; and the component B is prepared from the followingcomponents in parts by weight: 5-10 parts of butyl acetate, 5-10 parts of acetone and 216-289 parts of aromatic hydrocarbons. The product can form a firm adaptor with asphalt, modified asphalt and acement road surface, can avoid influences, on paint reaction activity, of soluble during MMA double-component marked line construction; and the formed mark line is good in adhesion force, is great intoughness, is high in hardness, is good in wear resistance, is strong in pollutant resistance, and is bright in color, so that the use time of the marked line can be prolonged; and the flammable and combustible risk is avoided in each link of production, transportation and construction, so that life safety of an operator and people around of each link of production, transportation and constructionis ensured.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a low-toxicity flame-retardant two-component marking primer and a preparation method thereof. Background technique [0002] During the construction of MMA two-component marking paint, the petroleum resin and synthetic rubber contained in the ordinary marking primer will be dissolved. At the same time, the asphalt and modified asphalt in the road surface will be dissolved, and the dissolved petroleum resin and synthetic rubber will be dissolved. , asphalt, and modified asphalt will reduce the active components of MMA two-component coatings (among them, the active components are active monomers, initiators, accelerators, and curing agents), resulting in reduced reactivity of the reactant and prolonged curing time. The formed marking lines are yellowish and flowery, have low hardness, poor toughness, and low wear resistance, which shortens the service life of the markin...
