Embodiment 1

[0040]After the harvested eucommia seeds are washed and dried, the seed skins and kernels are separated, the eucommia seed skins are taken, crushed, and passed through a 20-mesh sieve to obtain eucommia seed powder. Take 100g of Eucommia ulmoides seed powder and extract with ethanol to obtain 1.8g of Eucommia ulmoides resin by alcohol method. The verification by the Soxhlet extraction method shows that the extraction rate of Eucommia resin is 90%. According to the formula in Table 2, take 0 part and 1 part of alcohol-processed eucommia resin and styrene-butadiene rubber (SBR-1500) to mix, add zinc oxide, stearic acid, anti-aging agent and other additives and mix well, add carbon black, and finally Add accelerator and sulfur, mix until the upper and lower surfaces are smooth and uniform, take the glue, and vulcanize, control the vulcanization temperature at 130°C, and the vulcanization time is 20 minutes and 17 minutes respectively. After vulcanization is completed, take the gl...

Embodiment 2

[0047] The harvested bark of Eucommia is washed, dried, crushed and passed through a 50-mesh sieve to obtain bark of Eucommia powder. Take 250g of eucommia bark powder and extract with acetone to obtain 10g of eucommia ulmoides resin by ketone method. The verification by the Soxhlet extraction method shows that the extraction rate of Eucommia resin is 95%. According to the formula in Table 4, take 0 parts and 5 parts of resin and butadiene rubber (BR-9000) to mix, add zinc oxide, stearic acid, anti-aging agent and other additives, mix well, add carbon black, and finally add accelerator After mixing with sulfur until the upper and lower surfaces are smooth and uniform, take the rubber and vulcanize. Control the vulcanization temperature at 145°C, and the vulcanization time is 13 minutes and 11 minutes respectively. After the vulcanization is completed, take the glue, cut samples, and conduct performance tests.

Embodiment 3

[0054] The harvested eucommia leaves are washed, dried, crushed and passed through a 70-mesh sieve to obtain eucommia leaf powder. Take 250g of eucommia leaf powder and extract with ethyl acetate to obtain 15g of eucommia resin by ester method. The verification by Soxhlet extraction method shows that the extraction rate of Eucommia resin is 80% (the content of Eucommia gum accounts for 8%). According to the formula in Table 6, take 0 parts and 10 parts of resin and mix with neoprene (CR-322), add zinc oxide, stearic acid, anti-aging agent and other additives, mix well, add carbon black, and finally add accelerator After mixing with sulfur until the upper and lower surfaces are smooth and uniform, take the rubber and vulcanize it. The vulcanization temperature is controlled at 160°C, and the vulcanization time is 19 minutes and 15 minutes respectively.

Abstract

The invention discloses a bio-based reinforced plasticiser-eucommia ulmoides resin and a preparation method thereof, and bio-based reinforced plasticiser-eucommia ulmoides resin and the preparation method thereof are applied to the field of rubber industry plasticisers. Traditional rubber plasticisers all come from fossil resources, belong to non-renewable materials and can deteriorate the mechanical property of rubber. The eucommia ulmoides resin can improve the processing property of the rubber and reduce energy consumption, also can improve the mechanical property of the rubber and overcome the defect that the traditional plasticisers achieve plastification and do not achieve reinforcement and is a novel, renewable, green and environment-friendly bio-based reinforced plasticiser. A rubber material modified by the eucommia ulmoides resin has the advantages that the Mooney viscosity is reduced, the vulcanizing time is shortened, the tensile strength and the tear strength are improved, the elongation at break is increased, and the dynamic fatigue property is improved. The eucommia ulmoides resin is an important composing part of comprehensive development of eucommia ulmoides gum, can enable by-products obtained through eucommia ulmoides gum production to be effectively utilized and has the advantages that the raw material utilization efficiency is improved, waste materials are changed into things of value, the environment is protected, the production process is simple and convenient, the production cost of the eucommia ulmoides gum is lowered, and the economic benefit and the social benefit are significant.

Description

technical field [0001] The invention is applied to the field of plasticizers in the rubber industry, and in particular relates to a new type of bio-based reinforced plasticizer-eucommia resin and a preparation method thereof. Background technique [0002] Generally, rubber materials have to go through three main processes of mixing, molding, and vulcanization to finally become a rubber product. Among the three processes of rubber processing, the mixing process consumes the most energy, so it reduces the rubber mixing process. The energy consumption will be the top priority of the overall energy saving and consumption reduction in the rubber industry. The addition of plasticizer can act as a lubricant in the rubber processing process, effectively reducing the resistance encountered in the rubber processing process, thereby achieving the effect of reducing energy consumption. However, excessive addition of plasticizers will damage the mechanical properties of rubber materials...
