Abstract
The invention discloses a production method for a polyurethane superfine fiber synthetic leather composite filtering material. The production method comprises the following steps: a polyurethane foamed material and polyurethane superfine fiber synthetic leather base cloth are spread out and stacked, or a polyurethane foamed material, polyurethane superfine fiber synthetic leather base cloth and a polyurethane foamed material are spread out and stacked in order, and the above composition is placed in a flat hot press. Hot pressing is carried out for 1-5min at a temperature of 180-250 DEG C and under a pressure of 0.15-0.35MPa, and a polyurethane superfine fiber synthetic leather composite filtering material can be obtained. The composite filtering material can release absorbed gas molecules slowly and stably, and thus flame of a gas ignition tool can burn stably. In addition, the synthetic leather base cloth and the polyurethane foamed material contain polyurethane resin components, in the hot pressing process, part of polyurethane resin is fused and softened at a high temperature, and therefore tight pasting between a layer and a layer is achieved, which can save a lot of adhesives, and is helpful for environment protection.
Description
Technical field
The present invention relates to a kind of production method of polyurethane ultrafine fiber synthetic leather composite filter material, particularly the production method of the polyurethane ultrafine fiber synthetic leather composite filter material of fuel in a kind of filtering gas fire-striking tool.
Background technology
Filtration pad in gas lighter, general employing is through heating the multilayer sponge pasted together, but the orifice throat ratio larger amt of sponge is also many, not strong to the adsorption capacity of fuel gas, release unstable gas, cause gas lighter flame easily to extinguish, can not use on long-time continuous stable ground.
Also someone adopts nonwoven fabric foam-rubber cushion, such as, in Chinese utility model patent (ZL201320592156.4) the employing pad of layer to be sponge intermediate layer be nonwoven fabric.But the space of nonwoven fabric is still larger, to the absorption of gas and releasing effect not ideal enough; And between the three-decker of this utility model, need to adopt binder heating to paste, and this patent does not provide concrete production technology.
Summary of the invention
The object of this invention is to provide a kind of production method of polyurethane ultrafine fiber synthetic leather composite filter material, to overcome the defect that prior art exists.
Production method of the present invention, comprises the steps:
(1) the polyurethane ultrafine fiber synthetic leather base cloth of to be the polyurethane foamed material of 10 ~ 20mm and thickness by thickness be 0.6 ~ 1.0mm launches to pave and stacked, or be 10 ~ 20mm polyurethane foamed material by thickness, to be 0.6 ~ 1.0mm polyurethane ultrafine fiber synthetic leather base cloth and a layer thickness be a layer thickness that 10 ~ 20mm polyurethane foamed material launches to pave successively and stacked, is placed in the flat-bed press that all can heat up and down;
The density of described polyurethane foamed material is 18 ~ 25kg/m
3, be preferably 20 ~ 23kg/m
3, be commercially available prod;
Described polyurethane ultrafine fiber synthetic leather base cloth is reticulate the high density non-weaving cloth of structure for skeleton with superfine fibre processing complexing, through impregnation polyurethane resin, solidify washing, again through composite that decrement fibrillation is obtained, for commercially available prod, can bibliography: Qu Jianbo. synthetic leather technology [M]. Chemical Industry Press, method disclosed in 2010. is produced and is obtained;
(2) then under the pressure of 180 ~ 250 DEG C of temperature, 0.15 ~ 0.35MPa, hot pressing 1 ~ 5min, can obtain described polyurethane ultrafine fiber synthetic leather composite filter material.
Compared with prior art, the polyurethane ultrafine fiber synthetic leather base fabric structure that the production method of a kind of polyurethane ultrafine fiber synthetic leather composite filter material of the present invention adopts is fine and close, but the release structure between superfine fibre wherein and polyurethane and polyurethane cell structure further provide enough gas absorption spaces, the gas molecule that stably release is adsorbed can be relaxed, gas fire-striking tool flame stabilization is burnt; And, all containing polyurethane resin composition in synthetic leather base cloth and polyurethane foamed material, in hot pressing; the polyurethane resin at high temperature melting of part is softened; thus reach closely pasting between layers, therefore can save a large amount of binders, also contribute to environmental protection.
