Abstract
The invention mainly discloses a production process of aerating sponge, and in particular relates to sponge taking polyalcohol and isocyanate as main materials. The sponge comprises the following auxiliary materials: pore-forming agent, catalyst, main sponging agent water and auxiliary sponging agent methylene dichloride. The raw materials are uniformly mixed and then distributed in an oven of a production line through a distributor at a flow rate of 150 to 320kg/min; and the foaming of an entire piece of sponge is carried out inside the oven at the temperature of between 35 and 50 DEG C for 3 to 5 minutes. The production process has the advantages that aerating sponge produced by adopting the process has outstanding aerating effect and a user can feel the air current formed by air uprush obviously when pressing the sponge; and when pressed by hand, the sponge can retain the handprint for 5 to 8 minutes after the hand leaves.
Description
Technical field
The present invention relates to a kind of production technique, be specifically related to the common full-automatic sponge streamline foaming machine of a kind of employing and carry out the production of bulk sponge, form slow-recovery sponge with flatulence feature with slow-recovery sponge of flatulence feature.
Background technology
Along with growth in the living standard, people require also more and more higher to the comfortableness of household.Ordinary soft sponge product one is to soft, flexible and adopted in a large number by household.But in use, the ordinary soft sponge product exists big to the human vas resilient pressure, and the shortcoming that comfortableness is relatively poor makes that the application category of ordinary soft sponge is limited to.
In order to remedy the deficiency of ordinary soft sponge, release a kind of molding flatulence slow-recovery sponge in the market, the characteristics of this sponge are for to adjust shape automatically according to the shape and the temperature of health, effectively the human pressure is dissolved and be zero-pressure, offset reaction force, for you provide average, real support, make the position of health Long contact time be in pressure-less state, do not hinder blood circulation and be difficult for to produce tired and ache, slow-recovery sponge is used for hospital, can be patient comfort to greatest extent is provided, can prevent the generation of bedsore effectively.The superiority of flatulence slow-recovery sponge is that the ordinary soft sponge is difficult to match in excellence or beauty, and still, the manufacturing of this sponge always is adopts the injection moulding batch technology, once only to make the long-pending 0.5m that is not more than of a block
3The flatulence slow-recovery sponge, only be suitable for to make little goods such as pillow, toys, this production technique has seriously hindered the further expansion of flatulence slow-recovery sponge Application Areas, incompatibility scale operation, inefficiency.
Summary of the invention
The present invention has solved this problem by Research on Process, can produce volume greater than 0.5m with continuous production processes
3The slow resilience bubble of the flatulence of (volume can infinitely great) is continuous, can make the large volume goods except that pillow, the little goods of toys, as mattress etc.
Main task of the present invention is to provide a kind of slow-recovery sponge and technology thereof with flatulence feature, is specifically related to a kind of employing streamline and carries out bulk sponge high-level efficiency, low cost production, forms the slow-recovery sponge with flatulence feature.
In order to solve above technical problem, the production technique of a kind of aerating sponge of the present invention, this technology by select materials, prepare burden, foaming, moulding cut into finished product again and constitute; It is characterized in that: described making component and proportioning are as follows: with 100 parts of polyvalent alcohols is example, and isocyanic ester is 40--70 part, and whole hole agent is 1.4--2.5, and catalyzer is 0.1--0.4 part, main whipping agent water 2--3.5 part, auxiliary blowing agent methylene dichloride 0--10; With behind the above-mentioned raw materials uniform mixing by sparger with the flow distribution of 150--320 kg/minute in the baking oven of streamline, to carry out the foaming of monoblock sponge under the temperature of 35--50, foamed time is 3--5 minute in baking oven.
Further, described whole hole agent is a polysiloxane polyether copolymer.
Further, described catalyzer is a triethylene diamine solution.
The invention has the advantages that: adopt the Qihai silk floss that rises of this explained hereafter, the gas effect that rises is obvious, obviously feels the air-flow that the gas upper punch forms when pushing.In addition, owing to adopt the production method of streamline, have the advantage that discharging is fast, efficient is high, compare with the injection moulding of general flatulence slow-recovery sponge, speed has improved at least 100 times; Importantly, compare with the injection moulding of general slow-recovery sponge, this streamline does not need a kind of sponge of shape to be equipped with a mould, only the monoblock sponge need be produced good back and cut into the shape that needs with cutters and get final product, and has reduced unnecessary die cost.
