Abstract

The present invention relates to a new-type ethylene propylene terpolymer, and its production process and application for making plastic sports ground and plastic cement track. It is characterized by that it is made up by using EPT rubber, filling agent, coupling agent, pigment and vulcanizing agent through the procedures of proportioning, mixing and vulcanizing, and the said product possesses excellent tensile strength of 0.3-1.0 Mpa and extension rate of 300-700%, and possesses good cohesiveness with polyurethane, so that it possesses extensive application range.

Description

A kind of ethylene propylene terpolymer and production technique thereof

The present invention discloses a kind of ethylene propylene terpolymer and production technique thereof, and product belongs to organic polymer material organic synthesis rubber.

The at present domestic ethylene-propylene diene copolymer that makes is difficult to bond with urethane, so can't satisfy the requirement that ethylene-propylene diene copolymer is adopted on plastic cement race track that International Track and Field Association requires or athletic ground, because ethylene-propylene diene copolymer has the excellent specific property of the anti-weathering age that can't compare in the rubber elastomer, be the prerequisite that obtains high-quality plastic cement race track or athletic ground so make qualified ethylene-propylene diene copolymer.

The objective of the invention is to disclose a kind of ethylene propylene terpolymer and production technique thereof, the product that obtains has good tensile strength 0.3～1.0Mpa, elongation 300～700% has good cohesiveness with urethane, can make satisfactory plastic cement race track and athletic ground.

The present invention is achieved in that ethylene propylene terpolymer is made up of following material:

1. terpolymer EP rubber;

2. weighting agent: lime carbonate, magnesiumcarbonate, potter's clay, calcium sulfate, barium sulfate, white carbon black zinc oxide, choose any one kind of them or several.

3. coupling agent: anilinomethyl triethoxysilane, Υ glycidyl oxypropyl trimethyl silane, vinyltriacetoxy silane, ethyl group three silane, Υ aminopropyl three ethoxy silane, vinyl silane tri-butyl peroxy, Υ propyl trimethoxy silicane, optional to two kind.

4. vulcanizing agent: sulphur, ammonium dibutyldithiophosphate, cadmium diethyl dithiocarbamate, tetramethyl-thiuram disulfide, dibenzothiazyl disulfide, aminodithiophosphate, TBTM tetrabutyl thiuram monosulfide, select two kinds or several.

5. pigment: titanium dioxide, zinc oxide, red iron oxide, iron oxide green, iron oxide yellow, ultramarine, chromium trioxide, cadmium red, select for use as required.

The ethylene propylene terpolymer material prescription is than (weight ratio): 100 parts of terpolymer EP rubbers, 50～300 parts of weighting agents, 5～30 parts of pigment, 0～5 part of coupling agent, 1～5 part of vulcanizing agent.

Manufacture craft may further comprise the steps: 1. by adding terpolymer EP rubber and coupling agent than part, mixing in mixing roll; 2. by adding weighting agent and pigment again, in mixing roll, continue mixing than part; 3. add vulcanizing agent, under 150 °～200 ℃ conditions, vulcanized 10～40 minutes; 4. the ethylene propylene terpolymer of moulding is pulverized granulating, particle size analysis is stand-by finished product in 0.5～2mm or pulverizing in accordance with regulations.

Embodiment 1: ethylene propylene terpolymer is applied in the making runway, the material prescription ratio: 100 parts of terpolymer EP rubbers, and 200 parts of weighting agents, 30 parts of pigment, 5 parts of coupling agents, 5 parts of vulcanizing agents are ground into micelle after the mixing sulfuration, and particle diameter is at 0.5～2mm.

Embodiment 2: ethylene propylene terpolymer is applied in makes the athletic ground, the material prescription ratio: 100 parts of terpolymer EP rubbers, and 300 parts of weighting agents, 10 parts of pigment, 5 parts of coupling agents, 5 parts of vulcanizing agents are ground into micelle after mixing, the sulfuration, and particle diameter is at 0.5～2mm.

Product of the present invention has good tensile 0.3～1.0Mpa, and elongation 300～700% has good cohesiveness with Polyoxyethylene este, and the plastic cement race track of making of it can reach the desired standard of International Track and Field Association, has a good application prospect.
