Problems solved by technology

At present, most of the car interior ceiling materials are made of thermoplastic rigid polyurethane plastic foam boards. Although foaming agent substitutes are used in the foaming process of this type of plastic foam boards, ODS cannot be fundamentally eliminated, and the foam density is relatively low. Large, poor extensibility, unsatisfactory molding and composite performance, which affects and restricts the simultaneous development of interior decoration and overall automobile technology

Embodiment 1

[0007] Embodiment 1: In parts by weight, 40 parts of polyether polyols are mixed with 60 parts of polyester polyols, 1 part of foam stabilizer, 3 parts of water and 0.1 part of amine catalyst are added thereto, and then mixed with After 140 parts of polyisocyanate is mixed, it is foamed and processed into a foam board for the interior roof of passenger cars.

Embodiment 2

[0008] Embodiment 2: In parts by weight, 50 parts of polyether polyols are mixed with 50 parts of polyester polyols, 0.8 parts of foam stabilizer, 4 parts of water and 0.08 parts of amine catalysts are added thereto, and then mixed with After 150 parts of polyisocyanate is mixed, it is foamed and processed into a foam board for the interior roof of passenger cars.

Embodiment 3

[0009] Embodiment 3: in parts by weight, 60 parts of polyether polyols are mixed together with 40 parts of polyester polyols, 0.9 parts of foam stabilizers, 5 parts of water and 0.09 parts of amine catalysts are added thereto, and then mixed with After mixing 130 parts of polyisocyanate, it is foamed and processed into a foam board for the interior roof of passenger cars.

[0010] The typical foam performance that the foam board finished product that above embodiment makes has is as following table:

[0011] Density:

[0012] Due to the use of water as the foaming agent, ODS is completely eliminated, and the damage to the atmospheric ozone layer is fundamentally eliminated, which is economical and environmentally friendly; its stock solution has good fluidity, uniform product density, good cell structure, and high compressive strength. Ideal product for foam boards for car interior ceilings.

Abstract

The present invention discloses a decorative bubble panel used in vehicles, in particular to a bubble panel for a canopy of inner decoration, which is characterized in that the bubble panel is produced by a froth technology of the following weight percentage of materials: a mixture of polyether polyol and polyester polyol which comprises 40-60 percent of polyether polyol, 0.8-1 percent of bubble stabilizer should be added, material A comprises 3-5 percent of water and 0.08-0.1 percent of amine activator, mixed with isocyanate(material B) to create a combined material, with a froth proportion of A:B=1:1.3-1.5, be frothed to form a bubble panel for a canopy of inner decoration; the production is characterized in even density, good structure of bubble holes and high pressure resistance, washing out ODS completely, stopping the destruction of the ozonosphere of the atmosphere radically.

Description

1. Technical field [0001] The invention discloses a foam board, in particular to a thermoplastic rigid polyurethane foam board used for the interior ceiling of a passenger car. 2. Background technology [0002] Along with social development and scientific and technological progress, people pay more attention to the performance and driving comfort of cars, especially cars. The lightweight, comfort and environmental performance of vehicles are particularly important. Update higher requirements. At present, most of the car interior ceiling materials are made of thermoplastic rigid polyurethane plastic foam boards. Although foaming agent substitutes are used in the foaming process of this type of plastic foam boards, ODS cannot be fundamentally eliminated, and the foam density is relatively low. Large, poor extensibility, unsatisfactory molding and composite performance, which affects and restricts the simultaneous development of interior decoration and overall automobile techn...
