Abstract
The invention relates to a regenerated sponge with the good elasticity and the large density, and belongs to the technical field of sponge products. The regenerated sponge with the good elasticity and the large density is prepared from, by weight, 100-150 parts of sponge scraps, 35-50 parts of regenerated sponge glue and 1-3 parts of a sterilizing agent. According to the regenerated sponge with the good elasticity and the large density, the sponge scraps are effectively utilized, the specially-prepared regenerated sponge glue is adopted, two times of sterilization and disinfection are performed, and the production cost is greatly reduced. Accordingly, the regenerated sponge is good in elasticity and tolerance, nondeformable, free of poison and foreign smell and high in density and pressure resistance and can be widely applied to the fields of manufacture of sofas, mattresses, executive chairs, sport equipment and the like.
Description
Technical field
The present invention relates to a kind of good springiness, renewable sponge that density is large, belong to sponge product technical field.
Background technology
Renewable sponge is a kind of novel product, is a kind of sponge treatment process of global general-use.Renewable sponge belongs to the recycling of polyurethanes product industrial waste.Its use value is not second to sponge, and it de-tastes compressed moulding by industrial sponge tankage through pulverizing, stirring glue steam high-temperature sterilization sterilization.Use from production cost and greatly reduce production cost, the product making various density can be needed according to client, can be widely used in and make sofa, mattress, executive chair, sports equipment, as products such as sponge mat, sponge body-building cushion, sponge mat proper, sponge automobile cushions, this kind of product is accepted extensively by countries in the world.But current renewable sponge is reprocessing product due to it, so mostly lose its good springiness of sponge, indeformable feature.
Summary of the invention
The object of the invention is to solve the weak point that above-mentioned prior art exists, the renewable sponge providing a kind of environmental protection, the good springiness of nontoxic free from extraneous odour, density large and complete processing thereof.
The present invention is achieved by the following technical solutions:
The renewable sponge that good springiness, density are large, its special character is to be made up of following raw material by weight ratio: sponge tankage 100-150 part, Regenerative sponge glue 35-50 part, sterilant 1-3 part;
Described Regenerative sponge glue is mixed by polyether glycol, methylcarbonate, poly methylene poly phenyl poly isocyanate, dibutyltin dilaurate, dibutyl tin laurate;
Described sterilant is Peracetic Acid;
Described a kind of good springiness, the renewable sponge that density is large, be made up of the raw material of following optimum proportioning by weight: sponge tankage 120 parts, Regenerative sponge glue 40 parts, 2 parts, sterilant;
A complete processing for the renewable sponge that good springiness, density are large, its special character is to comprise the following steps:
(1) sponge tankage are put into pulverizer, be ground into sponge particle;
(2) the sponge particle of step (1) is put into reactor, add Regenerative sponge glue, stir, speed is 80-150r/min, stirs 10-30 minute, obtains work in-process;
(3) work in-process of step (2) are carried out just sterilization, work in-process are put into airtight sterilized room, sterilant is put into well heater, carry out heating fumigating, continue 2-3 hour;
(4) work in-process good for step (3) just sterilization are put into autoclave sterilizer again, carry out high-temp steam sterilizing 15-20 minute;
(5) work in-process that sterilizing is good are put into mould compressed moulding, air seasoning, then put into encloses container, nitrogen injection de-tastes, and cutting is packed.
A kind of good springiness of the present invention, the renewable sponge that density is large, effectively make use of the tankage of sponge, adopts special regeneration cotton glue, by twice sterilization and disinfection, greatly reduce production cost.Make its not only good springiness, good, indeformable, nontoxic free from extraneous odour of patience, and density is high, crushing resistance strong, fields such as making sofa, mattress, executive chair, sports equipment can be widely used in.
