preparation example Construction

[0012] The present invention provides a kind of preparation method of automobile instrument panel protection plate, wherein, described preparation method comprises:

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

[0014] (2) The mixture M1 is mechanically formed to obtain an automobile instrument panel guard, 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 is by uniformly mixing isocyanate compounds, polyether polyols, water, foam stabilizers, tertiary amine compounds and stannous octoate, and performing mechanical mo...

Embodiment 1

[0026] Mix toluene diisocyanate, polyether polyol with a weight average molecular weight of 800, water, polyvinyl alcohol, triethylamine and stannous octoate in a weight ratio of 100:50:3:0.5:0.3:0.15 to prepare The mixture M1 was obtained; after the mixture M1 was heated to 120°C, it was cast into a casting mold for solidification and water cooling, wherein the pressure in the casting mold was 20 MPa, and the solidification time was 5 minutes. During cooling, the cooling temperature was 20°C, and the cooling The time is 15 minutes, and finally the automobile instrument panel shield A1 is obtained.

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

Embodiment 2

[0029] Diphenylmethane diisocyanate, polyether polyol with a weight-average molecular weight of 2000, water, alkanolamide, triethylenediamine and stannous octoate in a weight ratio of 100:60:7:1:0.4:0.25 The ratio is mixed evenly to prepare the mixture M1; after the mixture M1 is heated to 170°C, it is cast into a casting mold to solidify and water-cooled, wherein the pressure in the casting mold is 25MPa, and the solidification time is 8min. During cooling, the cooling temperature is 25°C, and the cooling time is 25 minutes, and the automobile instrument panel protective panel A2 is finally prepared.

[0030] The impact toughness, high temperature resistance and flame retardancy of A2 were tested, and 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...
