Problems solved by technology

However, polyurethane foam is not suitable for floor mats. The reason is that its main disadvantages are that it is prone to hydrolysis when exposed to water, and it is easy to change color under the action of ultraviolet rays, and the residual monomer toluene diisocyanate is relatively toxic. )" has related records

Embodiment 1

[0032] A kind of highly elastic foaming material based on polyolefin elastomer, including following preparation raw materials calculated by weight: polyolefin elastomer POE and low-density polyethylene LDPE mixed polymer 3kg, azodicarbonamide (AC) 300g , di-tert-butylperoxycumene (BIPB) 22g, stearic acid 30g, zinc oxide 40g, talcum powder 2kg. Among them, the polyolefin elastomer POE is specifically selected from ExxonMobil Vistamaxx 8210, and the mass percentage in the polymer is 100%; and its melt index is 5.0g / 10min; the low-density polyethylene LDPE is selected from Yangzi BASF 2426H, and the melt index is 2.3 g / 10min.

[0033] Its preparation method is as follows: Prepare the required raw materials as needed, put them in a closed rubber mixer for mixing and plasticizing treatment, wherein the temperature in the closed rubber mixer is 135°C and plasticize for 15 minutes and discharge; The material discharged from the machine is sent to the open mill for 15 minutes of open...

Embodiment 2- Embodiment 6

[0035] Except that the mass percent content of ExxonMobil Vistamaxx 8210 in the polymer is different, the types and dosages of other preparation raw materials are the same as in Example 1; and the preparation method is also the same as in Example 1. In Examples 2-6, ExxonMobil The specific mass percentages of Vistamaxx 8210 in the polymer are 90%, 80%, 70%, 60%, and 50%.

Embodiment 7

[0040] Other implementations and index methods are basically the same as in Example 6, except that the amount of filler talcum powder is 1.0 kg.

Abstract

The invention discloses a high-elasticity foam material based on a polyolefin elastomer as well as a preparation method and application of the high-elasticity foam material. The foam material with high elasticity is prepared from the polyolefin elastomer partially or wholly replacing a common polymer raw material; a prepared finished product not only is soft and has the Shore A hardness (smaller than 22) obviously superior to the Shore A hardness (more than 30) of a traditional material, but also is good in rebound resilience and high in elongation at break and has anti-fatigue and antiskid effects; in addition, molecules of the polyolefin elastomer do not contain oxidation-sensitive carbon-carbon double bonds, and therefore, the finished product has more excellent anti-aging property; theprepared material does not contain harmful substances such as formaldehyde and a plasticizer, further has no problem of dioxin generated by chlorides and is high in safety and environment friendliness; the preparation method can be directly used on an original production line without increasing technological processes and is suitable for industrial production; and the production improvement costis reduced.

Description

technical field [0001] The invention relates to the field of foaming materials, in particular to a highly elastic foaming material based on polyolefin elastomer and its preparation method and application. Background technique [0002] Foaming material refers to the foaming material that gasifies and generates bubbles inside the material to make it a porous material. It has the advantages of light weight, high specific strength, excellent insulation performance, significant cushioning capacity and strong adsorption capacity, and has been widely used. In the automotive industry, construction industry, packaging industry, agriculture, water treatment and air filtration and other fields; such as the manufacture of foam plastics, foam rubber, foam resin, etc. [0003] The main characteristic of polyolefin (mainly polyethylene or EVA) foam floor mats used in children's crawling mats and home improvement materials is a combination of flexibility and rigidity, that is, a combination...
