Abstract

The invention relates to the technical field of production technologies of foamed cotton, and discloses a production technology of environment-friendly foamed cotton. The production technology of theenvironment-friendly foamed cotton comprises the steps of firstly, mixing and plastifying corresponding components of a material and reinforcing filler, and conducting primary banburying treatment; secondly, adding zinc oxide and stearic acid into a product obtained in the reaction for secondary banburying treatment; then adding a foaming agent, a foaming cross-linking agent, a PU colorant, an odor elimination agent and a stabilizer for tertiary banburying treatment; and finally, carrying out a milling-sheet extruding-cutting-foaming-cooling treatment technology process in sequence to obtain the polyurethane environment-friendly foamed cotton at last. According to the physical and chemical performance of the reactant components, reasonable sectional banburying treatment is conducted, thusthe output rate and quality of the foamed cotton are effectively improved, a mould-pressing physical gas foaming method is adopted, no chemical agents are used, thus chemical pollution is avoided, thetechnology is more environmentally friendly, and by controlling ageing and temperature of the reaction, foamed particles which are even in foam cell, controllable in size and controllable in foamingdensity can be obtained.

Description

technical field [0001] The invention relates to the technical field of foamed cotton manufacturing technology, in particular to a formula of environmentally friendly foamed cotton and a manufacturing process thereof. Background technique [0002] Foam cotton refers to materials containing pores, such as polystyrene foam board, polyvinyl chloride foam insulation board, polyurethane foam, etc. Generally, products on the market such as foamed plastics, pearl cotton, foamed rubber, water-swellable sealant, polysulfide sealant, etc. belong to the series of foamed products. Such as: PEF / / EVA / EPDM / rubber-plastic closed-cell foam and EPE pearl cotton / XPE polyethylene chemical cross-linked foam / IXPE electronic radiation cross-linked foam and other products. Water-swellable waterproof glue, polysulfide sealant, composite foam waterproof board, foam packaging box, foam packaging liner and EVA foam taekwondo mat, foam assembled floor mat, sealing rubber mat, etc. . [0003] The commo...
