Description
Technical field:
The present invention relates to steep continuous technical field, refer in particular to a kind of process for producing hot-press high frequency foam cotton.
Background technology:
The bubble silk floss often is used in the industry of furniture, underwear, vamp, automobile or the like.The PU of the foaming bubble silk floss, plane bubble silk floss often is used in heating, or through technical process such as superpotential, electric currents, fashions into the desired shape of various differences, solidifies the back typing in general mould.
The general bubble of tradition is continuous, all can be, but significant drawback is arranged through above-listed flow operations, and be exactly the spent time long (about 120～300 seconds), service temperature height (temperature required be about 180～220 ℃).Spent cost of labor, energy cost are too high.Therefore, hot-press high frequency foam cotton appears in the market.
The tradition hot-press high frequency foam cotton, the general operation temperature is 120～160 ℃, 6～12 seconds through heat energy and electric energy rapid shaping.But, this product in technical process, spent energy cost height, human cost is also high.The technical process diagrammatic illustration of its making is as follows: the bubble of producing foaming general TDI (polyethers), MDI (polyester) etc. is continuous, is soaked in subsequently in the solution of emulsification PVC, through the extruding after drying.The human cost height that it is wasted, and bubble is continuous dry through being difficult for after soaking, and the cost of waste is also high.More,, and contain DOP (Glacial acetic acid) composition, the rerum natura instability for the institute of environmental protection at present is not a product of recommending use because of the contained main component of the raw material that it used is PVC.Therefore, develop novel hot-press high frequency foam cotton, to meet environmental protection, the product that reduces energy cost becomes the problem of industry concern.
Summary of the invention:
The object of the present invention is to provide a kind of process for producing hot-press high frequency foam cotton, one step foaming is finished, and handles without any need for impregnation, and the making flow process is simple, and cost is low, the product compliance with environmental protection requirements.
For achieving the above object, the present invention adopts following technical scheme, make by TDI, PPG, amine catalyst, tin catalyst, PU resin-oatmeal, water, UV absorption agent, antioxidant, stiffening agent, colorant, pore-creating agent, ethylene glycol, the moulding of lime carbonate mixed foaming, its proportioning is as follows: PPG 0～100, stiffening agent 100～0, TDI 10～80, H
