Abstract
The invention mainly discloses a novel ventilated slow-resilience sponge, in particular relates to a ventilated slow-resilience sponge which ensures the aperture ratio of a product by adjusting raw materials and the proportioning of a product, so that the aperture ratio of the product is improved to over 95 percent without using a pore-forming agent or pore-forming silicone oil, and the ventilation property of the product is improved. When the ventilated slow-resilience sponge is used, a human body contacts the product and obviously feels that the product is floppy; and the product is more comfortable after being used for a long time, particularly in muggy summer.
Description
Technical field
The present invention relates to a kind of slow-recovery sponge, be specifically related to a kind of percentage of open area greater than 70% do not use pore-creating agent or perforate silicone oil synthetic ventilation property slow-recovery sponge.
Background technology
Slow-recovery sponge is since the exploitation of U.S.'s space development fifties in last century administration, and the product of production mostly percentage of open area is lower, is generally less than 70%.All use pore-creating agent or perforate silicone oil in process of production, the product ventilation property is low, and comfortableness is poor.
Summary of the invention
Main task of the present invention is to provide a kind of novel ventilated slow-resilience sponge, is specifically related to a kind of pore-creating agent or perforate silicone oil of not using and improves the product percentage of open area, to improve the ventilation property of product.
In order to solve above technical problem, described component of a kind of novel ventilated slow-resilience sponge of the present invention and proportioning are as follows: with two kinds of polyether glycols and a kind of polymer polyatomic alcohol 100 weight parts is standard, tolylene diisocyanate is 28--45 part, whole hole agent is 0.5--1.8 part, catalyzer is 0.13--0.55 part, whipping agent water 1--3.2 part.
Further, the weight part of described two kinds of polyether glycols and polymer polyatomic alcohol is respectively Mn700 polyether glycol 32.5--70 part, Mn3000 polyether glycol 20--42.5 part and Mn6000 polymer polyatomic alcohol 10--25 part.
Further, described polyether glycol is Mn700 polyether glycol and Mn3000 polyether glycol.
Further, described whole hole agent is described polysiloxane polyether copolymer.
Further, described catalyzer is triethylene diamine and stannous octoate, and wherein triethylene diamine accounts for 0.1-0.4 part, and stannous octoate accounts for 0.03-0.15 part.
The manufacturing process of above-mentioned novel ventilated slow-resilience sponge is as follows: with above-mentioned main raw material: Mn700 polyether glycol, Mn3000 polyether glycol and Mn6000 polymer polyatomic alcohol inject earlier in separately the container in proportion separately, will put in order hole agent and catalyzer again and inject according to the above ratio separately in the container.And all containers all are communicated in the effervescent nozzle by pipeline, and in order to control the blending ratio of raw material more accurately, pipeline is provided with the magnetic valve that is communicated with CPU.
In addition, for manufacturing that realizes novel ventilated slow-resilience sponge of the present invention and the foaming that can accomplish the bulk sponge, foaming machine of the present invention is the foaming lathe of common bulk sponge foaming with crawler belt both sides band baking oven.Why want bulk sponge foaming and do not select the foaming of fritter sponge to be because: the foaming of fritter sponge is mould of a sponge, if the size shape difference of sponge, that die sinking again improves production cost.Adopt the foaming of bulk sponge, can cut into arbitrary shape with the vibrating blade sponge cutting machine to the bulk sponge then, convenient and swift.
The process of raw material foaming is: raw material is sprayed onto on the crawler belt of foaming lathe by effervescent nozzle, transmit on foaming limit, crawler belt top, the baking oven of crawler belt both sides is except providing the temperature of needed 35-50 ° of foaming, the effect of also serving as baffle plate, the width of control sponge, the height of sponge is then controlled by the flow of raw material and the transfer rate of crawler belt, among the present invention by the flow control of nozzle ejection raw material in the 150--320 kg/minute.The time of this sponge foaming generally only needed get final product in 3-5 minute.
After the foaming of bulk sponge is finished,, can cut into arbitrary shape by the cutting of sponge cutting machine.
The invention has the advantages that: the present invention guarantees the percentage of open area of product by the adjustment to products material and proportioning, makes this product not use pore-creating agent or perforate silicone oil to improve the goods percentage of open area to greater than 95%, and the product ventilation property is improved.During use, human body contacts with these goods, feels that obviously these goods are soft, the long-time use, and particularly in sultry summer, comfortableness is better.
