Example Embodiment

[0012] The present invention provides a method for preparing an automobile dashboard guard plate, wherein the preparation method includes:

[0013] (1) Mix isocyanate compound, polyether polyol, water, foam stabilizer, tertiary amine compound and stannous octoate evenly to prepare mixture M1;

[0014] (2) The mixture M1 is subjected to mechanical molding to obtain an automobile instrument panel guard plate, wherein,

[0015] Relative to 100 parts by weight of isocyanate compounds, the content of polyether polyol is 40-65 parts by weight, the content of water is 1-10 parts by weight, the content of foam stabilizer is 0.2-1.5 parts by weight, tertiary amine The content of the compound is 0.1-0.5 parts by weight, and the content of stannous octoate is 0.1-0.3 parts by weight.

[0016] The present invention mixes isocyanate compounds, polyether polyols, water, foam stabilizers, tertiary amine compounds and stannous octoate uniformly, and mechanically molding to prepare automobile instrume...

Example Embodiment

[0025] Example 1

[0026] Toluene diisocyanate, polyether polyol with a weight average molecular weight of 800, water, polyvinyl alcohol, triethylamine and stannous octoate are mixed uniformly in a weight ratio of 100:50:3:0.5:0.3:0.15 to prepare The mixture M1 is obtained; after heating the mixture M1 to 120°C, it is cast into the casting mold to solidify and water-cooled. The pressure in the casting mold is 20MPa and the solidification time is 5min. During cooling, the cooling temperature is 20°C. The time is 15 minutes, and finally the automobile dashboard guard plate A1 is produced.

[0027] The impact toughness, high temperature resistance and flame retardancy of A1 were tested, and the test results are shown in Table 1.

Example Embodiment

[0028] Example 2

[0029] Diphenylmethane diisocyanate, polyether polyol with a weight average molecular weight of 2000, water, alkyl alcohol amide, triethylene diamine and stannous octoate in a weight ratio of 100:60:7:1:0.4:0.25 Mix the mixture evenly to obtain a mixture M1; after heating the mixture M1 to 170°C, it is cast to solidify and water-cooled in the casting mold, where the pressure in the casting mold is 25MPa, and the solidification time is 8min. During cooling, the cooling temperature is At 25°C, the cooling time is 25 minutes, and finally the automobile dashboard guard plate A2 is produced.

[0030] The impact toughness, high temperature resistance and flame retardancy of A2 were tested. The test results are shown in Table 1.

Abstract

The invention discloses an automobile instrument panel protective plate and a preparation method thereof. The preparation method includes the steps that isocyanic acid lipid compounds, polyether polyol, water, a foam stabilizer, tertiary amine compounds and stannous octoate are evenly mixed, and a mixture M1 is prepared; the mixture M1 is subjected to mechanical forming to prepare the automobile instrument panel protective plate. Relative to 100 weight parts of isocyanic acid lipid compounds, the weight part of polyether polyol is 40-65, the weight part of water is 1-10, the weight part of the foam stabilizer is 0.2-1.5, the weight part of tertiary amine compounds is 0.1-0.5, and the weight part of stannous octoate is 0.1-0.3. The instrument panel protective plate has the effects of being high in impact toughness, resistant to high temperature and good in flame retardancy.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to an automotive instrument panel guard and a preparation method thereof. Background technique [0002] In recent years, with the continuous improvement of people's requirements for the quality of automobiles, more and more plastics that are light in weight, corrosion-resistant, shock-absorbing, and easy to form and process are being used in the automobile industry. Structural and functional parts. The instrument panel guard is an essential structural part in the car. When a car crash occurs, the instrument panel guard is easy to crack or break, which requires it to have high impact toughness. Under strong sunlight, the instrument panel The panel is often heated to above 120°C, which requires it to have high temperature resistance. Of course, in order to increase the safety performance of the car, the dashboard panel also needs good flame retardancy. It is difficult for existing instrume...
