Description
Technical field
The utility model belongs to the device of making the cross-linked polyolefin material with even, fine and closely woven, closed micropore, specifically a kind of irradiated crosslinked polyalkene foaming equipment.
Background technology
Make this material of the many cavitys in inside that obtain after blowing agent decomposes, gasification is expanded after in the base material of TPO material, evenly sneaking into blowing agent through heating, have very strong damping, heat-blocking action, be widely used in the insulation of equipment, the packing of commodity, especially pass through crosslinked foam polyolefin material, because of the swelling gasbag hole that its inner cavity is numerous sealing, intensity and heat-proof quality are better.At present, the mode of producing crosslinking polyolefin foaming mainly is chemical crosslinking foaming and physical crosslinking foaming, and the chemical crosslinking foaming makes its crosslinked post-foaming earlier through heating again with compression moulding after sneaking into crosslinking agent, blowing agent in the polyolefin substrate, for example:
11 days October nineteen ninety-five of Chinese patent, the denomination of invention of bulletin was: the manufacture method of cross-linked polyolefin foam (patent No. 85109232.2) relates to and having evenly, the cross-linked polyolefin foam of the tough and tensile and thick type of fine and closely woven closed porosity, its preparation method comprises, by melt flow rate (MFR) is polyolefin and the crosslinking agent of 0.1-5.0, blowing agent mixes mutually with the blowing promotor that can select to use and makes, its each component is measured adding in accordance with regulations, obtain crosslinkable, foamable resin combination, in the mould of reservation shape, molded resin composition under the condition of pressurization and heating, making its gel percentage is 10-70%, expansion rate is 1 to 3 times of initial volume, then under atmospheric pressure to the crosslinked of above-mentioned moulding but not the resin combination of foaming carry out heat foamable. make polyolefin foam.
Chinese patent bulletin on November 27th, 2000, denomination of invention is: the manufacture method (patent No. 00132548.5) of open coiled continuously at ordinary pressure formula foam polyethylene relates to a kind of manufacture method of open coiled continuously at ordinary pressure formula foam polyethylene, with constituent, behind mixing arrangement and film generation device, batch by foam device foamable, cooling, make type continuously rolled foamed products; Also can be with the reinforcement material, through the paper device, give foaming again after fitting with the film that is shaped and cooling is batched, promptly get compound rolled foamed product.Have that method for making is simple and easy, production efficiency is high, uniform intensity and jointless continuous foamed body.
Chinese patent was announced on 01 16th, 2002, denomination of invention is: the production technology of cross-linked foam polyolefin material (patent No. 00110602.3), the production technology that relates to a kind of cross-linked foam polyolefin material specifically are to adopt (1) successively, with common process polyolefin, crosslinking agent, blowing agent are made expandable polyolefine material; (2), with the above-mentioned expandable polyolefine material heating that makes, carry out crosslinkedly, make its crosslinking degree reach 50-99%, save crosslinking with radiation technology; (3) above-mentioned sheet material after crosslinked is delivered to shake table in vibration work, is continued sheet material is heated to more than the decomposition temperature of blowing agent, to the blowing agent residual quantity less than 5% of blowing agent input amount, promptly make cross-linked foam polyolefin material.
Above-mentioned three inventions had both disclosed sheet material, the heating and mould pressing foaming of coiled material, the free foaming method of cross-linked foam polyolefin material, a kind of equipment that is different from mattress suspension method and the horizontal foamable of bath of liquid method has also been described, with shake table as horizontal foaming platform, realize that the cross-linked polyolefin material all can more freely stretch at three-dimensional when foaming, to solve big, the equipment manufacturing cost of the technology difficulty that adopts mattress to suspend, make that equipment manufacturing cost height and bath of liquid foaming solution consumption are big, reclaim and reuse difficulty, pollution sheet material, problem of environment pollution caused.But shaking platform still is not separated with the crosslinking polyolefin foaming base material after all fully.And only be intermittent soaring, contact with shaking platform this face still have hinder the length and width direction frictional force this one of be, can not make two-sided heating identical this be two, therefore still can cause the inconsistent of the two-sided form of expanded material and descend with the exterior quality of this face that contacts with shaking platform.
