Problems solved by technology

[0003] The drying condition of traditional automotive original paint is generally baked at 70°C for 50 minutes, which consumes a lot of energy, takes a long time to bake, and wastes manpower and material resources. Low cost and time-consuming and labor-intensive, it has been increasingly unable to meet the growing market demand for automotive paint, which has greatly restricted the rapid development of the domestic automotive industry.

Embodiment 1

[0028] Such as figure 1 As shown, a car paint with fast drying speed, the car paint includes a main agent and a curing agent, the raw materials of the main agent and the curing agent are respectively according to the volume content: main agent component: water-based epoxy resin 30 -55, pigment 15-35, anti-rust agent 1-5, anti-corrosion solvent 5-25, mica powder 5-10; curing agent components: ethylene glycol butyl ether 45-85, thickener 45-65; The volume ratio of the paint component and the curing agent component is 1-4:2.

[0029] Such as image 3 Shown, the invention discloses a kind of preparation method of automobile paint, and this method comprises the following steps:

[0030] A: Preparation of paint components:

[0031] (1) Transport 10-25 parts of water-based epoxy resin, 1-5 parts of anti-rust agent, 5-25 parts of anti-corrosion solvent, and 5-10 parts of mica powder into the mixing tank according to volume parts through a single delivery pump, and stir evenly .

Embodiment 2

[0043] A kind of preparation method of the car paint that drying speed is fast among the present invention comprises the following steps:

[0044] Start the controller, and set the number of parts of each component of the paint to be delivered through the controller. Each component of the paint is delivered independently through different single-part delivery pumps. The controller controls the stepping motor to start, and the stepping motor drives the drive shaft. 5 rotates, the drive shaft 5 drives the rotating cylinder 6 to rotate, and the conveying blade 8 on the rotating cylinder 6 is always in close contact with the inner wall of the housing 2 under the joint action of the elastic force of the spring 7, the gravity of the iron sand and the centrifugal force , the end of the conveying blade 8 is in sliding contact with the lower part of the housing 2 and maintains a sliding seal. An independent and airtight single-portion conveying space is formed between two adjacent conve...

Embodiment 3

[0051] A car paint with fast drying speed. The car paint includes a main agent and a curing agent. The raw materials of the main agent and the curing agent are respectively in parts by volume: main agent components: water-based epoxy resin 30-55, Pigment 15-35, anti-rust agent 1-5, anti-corrosion solvent 5-25, mica powder 5-10; curing agent components: ethylene glycol butyl ether 45-85, thickener 45-65; the paint The volume ratio of the component and the curing agent component is 1-4:2.

[0052] A preparation method for automobile paint, the method comprises the following steps:

[0053] A: Preparation of paint components:

[0054] (1) Transport 10-25 parts of water-based epoxy resin, 1-5 parts of anti-rust agent, 5-25 parts of anti-corrosion solvent, and 5-10 parts of mica powder into the mixing tank according to volume parts through a single delivery pump, and stir evenly ;

[0055] (2) Add 15-35 parts of pigment while stirring, and disperse at high speed in the mixing ta...

Abstract

The invention relates to a preparation method of an automobile paint with a high drying speed. The preparation method comprises the following steps: step A, preparing paint components; step B, preparing a curing agent component; and step C, preparing the automobile paint. Accurate matching of paint components is achieved through the single-part conveying pump, and the controller controls the stepping motor to complete conveying of accurate parts of paint components when a set value is reached through the counter and the controller, so that the matching of the paint components is accurately controlled, the matching speed is greatly increased, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of car paint, in particular to a method for preparing a fast-drying car paint. Background technique [0002] Automobile paint occupies an increasingly important position in my country's paint production. The surface of automobiles needs to be protected and decorated by paint. The quality of paint film is an intuitive evaluation of automobile quality, which will directly affect the market competitiveness of automobiles. The development and changes of automobiles put forward high-quality, low-cost and green technology requirements for paints. It is imperative to further develop scratch-resistant, stone-resistant, corrosion-resistant, high-hardness, beautiful and colorful multifunctional automotive paints. [0003] The drying condition of traditional automotive original paint is generally baked at 70°C for 50 minutes, which consumes a lot of energy, takes a long time to bake, and wastes manpower and material re...
