Described delayed catalyst is a potassium oleate,
The B material is isocyanates MDI, mixes A material and B material weight portion ratio: 1: 1.02.
The invention has the beneficial effects as follows:
1, air channel straight forming in mould, the inner chamber integrated stream line pattern that is in air channel directly at the compound one deck aluminium foil of air channel surface of internal cavity, makes that the friction of air channel inwall and air is little during moulding, it is smooth and easy to ventilate.And the aluminium foil water resistance is good, does not have the problem that entrucking is used the infiltration of air channel, back, leaked.
2, one-shot forming air channel technology, only need directly manufacturing top interior trim mould mfg. moulding die the time early stage, do not need to develop in addition air channel cover plate mould, saved the development cost of mold design, mould-manufacturing.
When 3, producing, the conjuncted one-shot forming in top interior trim and air channel does not need other moulding air channel cover plate, does not need other bonding air channel cover plate, has improved production efficiency.
4, the feature of environmental protection is good, and the adhesive bonding is not used in interior trim and air channel one-shot forming, can not cause entrucking to use problems such as the interior volatility harmful gas concentration height of back car.
5, strengthen the thermoset hard polyaminoester because the air channel integral material all is a Blanket, and imbed the iron bar enhancing when moulding, air channel intensity height is not easy distortion, breakage.
In sum, the inventive method can be with the interior trim air channel one-shot forming of passenger vehicle top, and the air channel ventilate smooth and easy, water resistance good, die cost is low, production efficiency is high, the feature of environmental protection is good, intensity is high.
