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
One, technical field
The invention discloses a kind of cystose, the thermoplastic hard polyurethane cystose that particularly a kind of automobile ceiling is used.
Two, background technology
Be accompanied by social development and scientific-technical progress, people pay attention to the automobile especially performance of car and the comfortableness of driving more, and the lightweight of vehicle, comfortableness and environmental-protecting performance are particularly important, and this has proposed to upgrade higher requirement just to the automobile ceiling articles for use.At present, the automotive interior roof base material adopts the thermoplastic hard polyurethane plastic foam plate mostly, though such plastic foam plate has used the whipping agent substitute in foaming process, but still can not fundamentally eliminate ODS, and foam density is bigger, extensibility is not good enough, and moulding, composite performance are unsatisfactory, influences and restricted the synchronized development of interior trim and automobile overall technology.
Three, summary of the invention
Purpose of the present invention is intended to overcome the deficiency of above-mentioned prior art, discloses the environment-friendly type cystosepiment for passenger car inner decoration ceiling that a kind of extrudate density is even, be easy to moulding, excellent property.
For achieving the above object, the technical solution used in the present invention is: a kind of cystosepiment for passenger car inner decoration ceiling, its special character is, it is processed through foam process by following raw materials by weight percent, be specially polyether glycol and account for the polyether glycol of 40-60% and the mixture of polyester polyol, to the suds-stabilizing agent that wherein adds 0.8～1%, 3～5% water and 0.08～0.1% amine catalyst are formed the A material, be made into the combination material with polyisocyanates (B material), foaming proportioning A: B=1: 1.3～1.5, be processed into cystosepiment for passenger car inner decoration ceiling through foaming.
The positively effect that compared with the prior art the present invention has is: adopt full water foamed technology, thoroughly eliminated ODS, avoided destruction that atmospheric ozone is become, the cystose ductility of making is good, can adapt to that distortion is big, the moulding of overlarge area goods and can not rupturing; The percentage of open area height, foam density is little, and good evenness meets the light-weighted development trend of car; Have excellent machine-shaping property and good compound self-enhancement; With the automobile ceiling of its preparation, have characteristics such as light weight, heat insulation, sound-absorbing, dimensional stability are good, and flexible design, convenient formation can be widely used in America and Europe, Japan and Korea S and homemade high-grade car.
Four, embodiment
For understanding the present invention better, the line face is done further detailed elaboration to it in conjunction with specific embodiments.
Embodiment 1: count by weight, the polyester polyol of 40 parts polyether glycols and 60 parts is mixed, to wherein adding 1 part of suds-stabilizing agent, 3 parts of water and 0.1 part of amine catalyst, with after 140 parts polyisocyanates mixes, be processed into cystosepiment for passenger car inner decoration ceiling again through foaming.
Embodiment 2: count by weight, the polyester polyol of 50 parts polyether glycols and 50 parts is mixed, to wherein adding 0.8 part of suds-stabilizing agent, 4 parts of water and 0.08 part of amine catalyst, with after 150 parts polyisocyanates mixes, be processed into cystosepiment for passenger car inner decoration ceiling again through foaming.
Embodiment 3: count by weight, the polyester polyol of 60 parts polyether glycols and 40 parts is mixed, to wherein adding 0.9 part of suds-stabilizing agent, 5 parts of water and 0.09 part of amine catalyst, with after 130 parts polyisocyanates mixes, be processed into cystosepiment for passenger car inner decoration ceiling again through foaming.
Typical froth performance such as following table that the cystose finished product that above embodiment makes has:
| Density: | 25～35kg/m 3 |
| Thermal conductivity (20 ℃): | ≤0.05W/m.K |
| Dimensional stability (20 ℃, 72hr): | ≤1.5％ |
| Compressive strength: | ≥130kpa |
Owing to adopt water as whipping agent, thoroughly eliminated ODS, fundamentally stopped destruction, economic environmental protection to atmospheric ozone layer; Its stoste good fluidity, extrudate density is even, and foam structure is good, and the ultimate compression strength height is the ideal product of cystosepiment for passenger car inner decoration ceiling.
Claims (1)
1. cystosepiment for passenger car inner decoration ceiling, it is characterized in that: it is processed through foam process by following raw materials by weight percent, be specially polyether glycol and account for the polyether glycol of 40-60% and the mixture of polyester polyol, form the A material to wherein adding 0.8～1% suds-stabilizing agent, 3～5% water and 0.08～0.1% amine catalyst, be made into the combination material with polyisocyanates (B material), foaming proportioning A: B=1: 1.3～1.5, be processed into cystosepiment for passenger car inner decoration ceiling through foaming.
