Abstract
The invention relates to a memory sponge with high supporting force and belongs to the technical field of sponge products. The memory sponge with the high supporting force is prepared from raw materials in parts by weight as follows: 50-80 parts of a polyether polyol mixture, 10-50 parts of polymer polyols, 23-48 parts of 4'4-diphenylmethane diisocyanate, 0.4-2 parts of silicone oil, 0.3-4 parts of a chain extender, 0.3-4 parts of a cross-linking agent, 0.8-5 parts of a catalyst and 1.5-3.5 parts of a foaming agent. According to the memory sponge with the high supporting force, properties of a sponge body are improved due to mixing of various polyols and addition of the chain extender and the cross-linking agent, so that the memory sponge has various excellent properties and the very good supporting property, the tensile and tear strength of the memory sponge is high, the compression deformation is small, and mechanical properties and low-temperature flexibility are substantially improved.
Description
Technical field
The present invention relates to a kind of memory foam with high anchorage force, belong to sponge product technical field.
Background technology
Memory foam is for NASA is a kind of hitech materials that space program is designed and developed at first.It designs for cosmonaut, helps to alleviate the pressure that cosmonaut bears in landing and flight course.Memory foam low resilience performance Producing reason, mainly because it has special microgranular texture---cellular structure: under the microscope, the unit that memory sponge is the most small, be made up of tiny cell compartments, the cell walls densification of cell can comprise air, but only have micropore and extraneous and other cellular communication, each cell structure very uniform micro size also very always.Unobstructed from the gas in general sponge between junior unit or isolated have huge different, and under barometric point effect, the situation of gas turnover cell determines the Main Mechanical of memory foam.After air is forced out cell, cell is crushed, although external force is dispelled, cell walls also has the elastic force of reduction, but because ventilating pit is tiny, air can not be got back in cell soon, cell can not recover shape soon, and the strength of resilience is suppressed, and the time that material deformation restores just has been extended.Because the industrial demand for memory foam is increasing now, also just not only its rebound performance is confined to its performance, and higher requirement be there has also been to its load-carrying properties, thus meet the demand of industrial aspect, but present its main purpose of most of memory foams is for non-industrial object, therefore its anchorage force performance is not enough.
Summary of the invention
The object of the invention is to the weak point solving the existence of above-mentioned prior art, a kind of memory foam with high anchorage force being applicable to industrial high-mechanic aspect is provided.
The present invention is achieved by the following technical solutions:
A kind of memory foam with high anchorage force, its special character is to be made up of following raw material by weight ratio: polyether polyol mixtures 50-80 part, polymer polyatomic alcohol 10-50 part, 4,4`-diphenylmethanediisocyanate 23-48 parts, silicone oil 0.4-2 part, chainextender 0.3-4 part, linking agent 0.3-4 part, catalyzer 0.8-5 part, whipping agent 1.5-3.5 part;
The polyvalent alcohol of described polyether polyol mixtures to be hydroxyl value be 35 ~ 45mgKOH/g and hydroxyl value are the mixture of the polyvalent alcohol of 110 ~ 150mgKOH/g;
Described chainextender is 1,6 one hexylene glycols, TriMethylolPropane(TMP), triglycol mixture;
Described linking agent is TriMethylolPropane(TMP);
Described catalyzer is the mixture of triethylene diamine and two (dimethylaminoethyl) ether;
