Polymer thermoplastic elastomer material MHP (Modified hot-melt polymer) composition and preparation method thereof

Abstract

The invention discloses a polymer thermoplastic elastomer material MHP (Modified hot-melt polymer) composition and a preparation method thereof. The composition is prepared from 1 to 30% of polypropylene, 1 to 30% of styrene rubber, 10 to 40% of rubber processing oil, 10 to 30% of a propenyl elastomer, 10 to 55% of inorganic filler, 0.3 to 1% of an antioxidant, 0.1 to 5% of a lubricant, 0 to 0.5% of toner, 0.5 to 10% of a compatibilizer, and 1-12% of petroleum resin. According to the polymer thermoplastic elastomer material MHP composition and the preparation method thereof, through adding odorless aluminic acid ester and the like into a system, the affinity of the filler and the polypropylene and the dispersibility of the filler are improved, thereby improving the tensile strength and impact-resistance strength of the polypropylene. Polymer thermoplastic elastomer material MHP provided by the invention has good mechanical processing property, is odorless and can be recycled; the anti-slip performance is particularly prominent mainly for household carpets, especially for bathroom mats, door mats and kitchen mats (under dry and wet ground conditions), and the safety performance is high.

Description

technical field [0001] The invention belongs to the technical field of polymer elastomer materials, and in particular relates to an odorless and color-adjustable polymer thermoplastic elastomer material (MHP, Modified Hot-melt Polymer) composition and a preparation method thereof. Background technique [0002] Polymer thermoplastic elastomer materials are usually materials with a low elastic modulus. Under room temperature conditions, they can be repeatedly stretched to more than 2 to 3 times their original length, and have the characteristic of returning to their original length after stress relief. Polymer thermoplastic elastomer materials have both the processing properties of thermoplastics and the physical properties of vulcanized rubber. It is an advantageous combination of the two materials of plastics and rubber. The anti-skid performance on the ground is poor, and there are serious safety problems.
