Embodiment 1

[0017] Weigh 15 kilograms of pentaerythritol, Add 8 kg and 45 kg of water into a three-neck flask equipped with a stirrer, stir thoroughly for 30 minutes, add 25 kg of water-based polyurethane emulsion PUD-336 within 10 minutes, stir at 500 rpm for 50 minutes, and finally use SRH high-shear homogenization The emulsification pump shears for 60 minutes to prepare a waterborne polyurethane flame retardant coating.

Embodiment 2

[0019] Prepare water-based polyurethane flame-retardant coating in the same manner as Example 1, except that no

[0020]

experiment example

[0022] Refer to GB15442.2-1995 "Large Plate Combustion Method" to measure the flame retardancy of the coatings in Examples 1 and 2. The flame retardant time of the coating in Example 1 is 561.5±3.0 seconds, and the flame retardant time of the coating in Example 2 is 368.5±3.5 seconds. It can be seen that after adding the flame retardant additive, the flame retardancy of the coating is significantly enhanced, and the results of Example 1 are compared with those of Example 2, and the difference is statistically significant (P<0.05).

Abstract

The invention relates to a water-based polyurethane flame-retardant coating for the automotive interior. The coating is prepared from the following raw materials in parts by weight: 15-50 parts of water-based polyurethane emulsion, 10-20 parts of flame retardant, 1-10 parts of flame-retardant aids and 30-50 parts of water. The automotive interior water-based polyurethane flame-retardant coating disclosed by the invention has enhanced flame-retardant property and can be widely applied to automotive interior coating.

Description

technical field [0001] The invention relates to the field of automobiles, in particular, the invention relates to a water-based polyurethane flame-retardant coating for interior of a vehicle. Background technique [0002] In recent years, with the development of productivity and the continuous improvement of people's quality of life, water-based polyurethane uses water as the main solvent, which has the advantages of non-polluting, non-toxic, good film-forming properties, good film flexibility, and strong adhesion. People cater to the requirements of low VOC emissions in coatings, so waterborne polyurethane coatings have developed rapidly in recent decades. However, the waterborne polyurethane coating itself is flammable, which limits its application and development. Therefore research and development has the novel waterborne polyurethane coating with good flame retardancy of great significance and huge market prospect. Contents of the invention [0003] The object of th...
