Problems solved by technology

[0002] Existing a kind of polyurethane rigid foam combination material is made up of polyether 4110, silicone oil (foam stabilizer), fluorodichloroethane (foaming agent 141B), catalyst, and this combination material product has the following disadvantages: (1 ) The temperature resistance is not high, and when the temperature is higher than 80 degrees Celsius, the foam body will expand and bubble and deform; (2) Due to the high viscosity of polyether 4110, it is difficult to stir and mix with other substances. Therefore, the existing combination material Only 1-fluorodichloroethane can be used as a blowing agent, and the use of 1-fluorodichloroethane as a blowing agent will not only destroy the atmosphere, but also cause damage to the environment, and the cost is relatively high

Embodiment Construction

[0018] The specific embodiment of the present invention is described as follows:

[0019] (1) Polyurethane rigid foam combination material for vehicles is characterized in that: it comprises the raw material formula of following mass fraction ratio:

[0020] Polyether 4110 60-40 parts,

[0021] Polyether 350 40-60 parts,

[0022] 2 to 3 parts of foam stabilizer,

[0023] Foaming agent 2 to 5 parts,

[0024] Catalyst 6-10 parts.

[0025] The preferred raw materials for the above formula are: silicone oil is preferred as a foam stabilizer; water is preferred as a foaming agent; and the catalyst is an amine catalyst, preferably a triethylenediamine catalyst.

[0026] In the above combination material formula, with the gradual increase of the addition of polyether 350, the high temperature resistance of the product is gradually improved, the viscosity of the product is gradually reduced, and the hardness of the product is also gradually reduced, so it is necessary to ensure th...

Abstract

The invention discloses a polyurethane hard bubble composite material and making method of car, which comprises the following parts: 40-60% polyether 4110, 40-60% polyether 350, 2-3% foam stabilizer, 2-5% foaming agent and 6-10% catalyst, wherein the materials are put into container to blend evenly to produce the product.

Description

technical field [0001] The invention relates to a foaming material for automobiles, in particular to a polyurethane rigid foam composite material for automobiles and a preparation method thereof, which can play the role of heat insulation and decoration. Background technique [0002] Existing a kind of polyurethane rigid foam combination material is made up of polyether 4110, silicone oil (foam stabilizer), fluorodichloroethane (foaming agent 141B), catalyst, and this combination material product has the following disadvantages: (1 ) The temperature resistance is not high, and when the temperature is higher than 80 degrees Celsius, the foam body will expand and bubble and deform; (2) Due to the high viscosity of polyether 4110, it is difficult to stir and mix with other substances. Therefore, the existing combination material Only 1-fluorodichloroethane can be used as the foaming agent, and the use of 1-fluorodichloroethane as the foaming agent will not only destroy the atmo...
