Abstract

PURPOSE:To obtain the titled foam rich in shock-absorbing resilience, improved adhesive property and vacuum moldability, and useful for automotive interior trim materials, etc., by expanding a resin composition consisting of a specific plyporpylene-butene copolymer. CONSTITUTION:A resin composition, consisting of 95-35wt% polypropylene- butene copolymer with 1-20% butene having 0.1-10 melt index and 5-65wt% polyethylene, etc., and containing a thermal decomposition type blowing agent, e.g. azodicarbonamide, a crosslinking agent, e.g. 2,5-dimethyl-2,5-di-(tertbutylperoxy)hexyne-3, etc. is molded and then expanded in an atmosphere at a high temperature.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for using a heat-resistant, dry-treated polyolefin 2-in@BM foam, which has been quietly developed into a pyrolytic type
Crystalline polyolefin mixed in J' @ 9Ii BVIIll EL composition - Foamed in one atmosphere A, and foamed cross-linked BORIOLET 2 in @ fat extrusion body 1
At the bottom, add 1 and a half 1-20% of crystalline polyolefin 2-g #I 3 12% butene, melt index (Ml) or L
Boliole 2 in which the butene contained in L1 to 10 is combined with the 1st to 20% propylene and butene to give the t-value.
This invention relates to a method for installing in@ag helmet foam.

(/J) The conventional 8@N failure type is bad for the purpose, and the crystalline polyoxysilane 2-in@fat that is intoxicated is easily foamed, but it is not easy. Vt-Nori is made with a foam that has been modified to the width of the A-nitrogen molding company.

Conventionally, when mounting the L cube olefin 2 ohm,
In advance, exfoliolefin @ generates tuna’s chestnut % property for chestnut compensation reaction.
I was in the range of the VC, scolded (/J Chikan), and I was able to understand the atmosphere, and I was able to capture the generation in the meiren polyoleain, and I was attending to Akira. In addition to the low tB degree Holienalene KEE-based Eikika Polymer 2 Inform, German XL-N has low heat conductivity and water absorption of less than half, making it widely useful as an IIT heat material.17

The noglobilene-butin combination of the present invention is made by combining propylene and butene at a ratio of 54'''c7IL+ in the presence of a stereoregular blood combination catalyst. The idea is to randomly copolymerize Sarutake when copolymerizing the block BcJ, and if it is copolymerized with the block BcJ, the melting point on the part side will be unbalanced, making it difficult to foam.0 Differential scanning pPJm Resistance (DSC) t: Judging from the peak temperature of 130 to 140°C, the propylene-butene lantam complex is yoke once from 100°C to around 160°C.
