Example Embodiment

[0021] Example 1

[0022] See figure 1 , This embodiment provides a method for preparing non-toxic, fireproof, and low-VOC silicone leather for automotive interiors, which includes the following steps:

[0023] Step 1: Apply 80 parts of silicone resin, 20 parts of organic solvent, 7 parts of color paste, and 0.3 platinum catalyst to a suitable release paper surface after mechanical mixing and deaeration. Place it in a dryer at 130°C and dry it. Dry and cure, get the surface layer;

[0024] Step 2: Coat 80 parts of silicone resin, 10 parts of organic solvent, 5 parts of color paste, and 0.3 part of platinum catalyst on the surface of the surface layer. Before curing, the substrate is laminated and placed in a dryer at 130°C. Drying and curing to form an adhesive layer combined with the substrate;

[0025] Step 3: Curing at 90°C for 6 hours, then separating and winding;

[0026] Step 4: Move the semi-finished product crimped in step 3 to the post-processing workshop, mix 50 parts of si...

Abstract

The invention discloses a preparation method of fireproof non-toxic automotive interior organic silicon leather. The method includes the steps: mixing and defoaming appropriate parts of organic silicon resin, organic solvents, color paste and platinum catalysts by the aid of machinery, coating the surface of suitable release paper with mixture, and drying and curing the release paper coated with the mixture in a dryer with the temperature of 125-135 DEG C to obtain a surface layer; coating the surface of the surface layer with appropriate parts of organic silicon resin, organic solvents, colorpaste and platinum catalysts, fitting a substrate with the surface layer before curing, and drying and curing surface layer fitted with the substrate to obtain a bonding layer combined with the substrate; ageing the bonding layer for 4-6 hours, and performing separating and winding; transferring a wound semi-finished product into a post-treatment workshop, uniformly stirring and mixing appropriate parts of organic silicon resin, organic solvents, platinum catalysts and nano-silicon dioxide by the aid of machinery to prepare a surface treatment agent, printing the surface treatment agent ontothe surface of the semi-finished product organic silicon leather, and drying and curing semi-finished product organic silicon leather to obtain finished product organic silicon leather. The organic silicon leather is free from toxicity, resistant to fire, good in abrasion resistance and long in service life, and VOC (volatile organic compound) release is low.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a method for preparing silicone leather for fireproof and non-toxic automotive interiors. Background technique [0002] With the improvement of people's living standards and the development of the automobile industry, there are more and more cases of automobile leather cushions and leather decorations, and the development prospects of automobile leather are very broad.
