Embodiment 1

[0031] A preparation method for a one-component automotive airbag cover paint, the method comprises the following processing steps:

[0032] (1) Add 30% thermoplastic polyurethane resin (EU86-X), 2% dispersant DISBERBYK2000, and 10% solvent xylene to the batching kettle in sequence, and stir for 15 minutes at a speed of 400 r / min. Then add 2% carbon black (FW200) slowly, accelerate to 800r / min after the addition is complete, disperse at high speed for 30 minutes, then transfer to a sand mill for grinding, and stop grinding when the fineness is less than 15 μm. This slurry is A component.

[0033] (2) Add 23% thermoplastic polyurethane resin (EU86-X) to the batching kettle, add component A, 5% barium sulfate (Blanc Fixe F), 5% nano-alumina (Nanophase ), 3% matting powder (OK607), 5% toluene, 15% butyl acetate, accelerate to 800r / min after complete addition, and disperse at high speed for 30min to obtain a single-component automotive airbag cover paint.

Embodiment 2

[0035] A preparation method for a one-component automotive airbag cover paint, the method comprises the following processing steps:

[0036] (1) Add 30% modified polyester polyol resin (PE-9624), 4% dispersant (DISBERBYK161), and 15% solvent xylene to the batching tank in sequence, and stir at a speed of 400r / min 15min. Then add 3% Phthalocyanine Green (BASF8730) slowly, accelerate to 800r / min after complete addition, disperse at high speed for 30 minutes, then transfer to sand mill for grinding, and stop grinding when the fineness is less than 15 μm. This slurry is A component.

[0037] (2) Add 20% hydroxy acrylic resin (FS-2050) to the batching kettle, add component A, 5% superfine talc powder (Liaoning Haicheng), and 3% matting powder ( OK520), 5% ethyl acetate, 15% butyl acetate, accelerate to 800r / min after complete addition, disperse at high speed for 30min, and become a one-component automotive airbag cover paint.

Embodiment 3

[0039] (1) First weigh 20% thermoplastic acrylic resin (LR-7697), 1% dispersant DISBERBYK110, and 10% solvent xylene, and add them to the batching kettle in sequence, and stir for 15 minutes at a speed of 400r / min. Then add 15% titanium dioxide (R706) slowly, accelerate to 800r / min after the addition is complete, disperse at high speed for 30 minutes, then transfer to a sand mill for grinding, and stop grinding when the fineness is less than 15 μm. This slurry is A component.

[0040] (2) Add 24% thermoplastic acrylic resin (LR-7651) to the batching kettle, add component A, 5% superfine talcum powder (Liaoning Haicheng), and 5% glass powder in sequence at a speed of 400r / min (Japan Ronsen VX-S), 5% toluene, 15% butyl acetate, accelerate to 800r / min after complete addition, and disperse at high speed for 30min to obtain a one-component automotive airbag cover paint.

Abstract

The invention relates to a single-component automobile supplementary restraint system cover paint and a preparation method thereof. The single-component automobile supplementary restraint system cover paint is prepared from the following components in percent by weight: 2-15 percent of pigment powder, 5-10 percent of filler, 0-3 percent of extinction powder, 40-60 percent of resin, 1-4 percent of dispersing agent, and 20-35 percent of solvent. The preparation method comprises the steps of: firstly, sequentially adding 30-60wt% of resin, the dispersing agent and 30-50wt% of solvent in a blending kettle, stirring uniformly at low speed; then slowly adding all the pigment powder, then stirring at a high speed for dispersing the pigment powder, grinding in a grinder till grain fineness is lower than 15 mu m, so as to obtain slurry; and adding the residual resin in the blending kettle, sequentially adding the slurry, the filler, the extinction powder and the residual solvent while stirring at a low speed, and then stirring at a high speed after the raw materials are all added, so as to obtain the single-component automobile supplementary restraint system cover paint. Compared with the prior art, the single-component automobile supplementary restraint system cover paint has the advantages of excellent adhesive force, no need of drop priming, no addition of a curing agent, cost and procedure saving, excellent abrasive resistance and scratch resistance, and the like.

Description

technical field [0001] The invention relates to a paint and a preparation method thereof, in particular to a single-component automotive airbag cover paint and a preparation method thereof. Background technique [0002] At present, there are four main types of soft airbag cover materials: copolyester elastomer (TPEE / COPE), TPO (or marked as TPE), PVC, and thermoplastic polyurethane (TPU). There are two main types of hard ones: polypropylene and PVC / ABS blister composite sheets. In the field of automotive industry paint, there are three main methods of painting airbag cover materials: 1. Three layers of bottom surface cleaning, that is, first spray a layer of primer on the substrate, then spray a layer of color paint, and finally spray One coat of clear varnish. 2. Two layers on the bottom surface, that is, spray a layer of primer on the substrate first, and then spray a layer of color paint. 3. Two-component single-coating, that is, spraying the topcoat directly without p...
