Embodiment 1

[0017] Example 1: The oilfield sludge rubber filler is prepared into a powdery oilfield sludge rubber filler with a particle size of less than 200 meshes and a moisture content of less than 0.5% using oilfield sludge as a raw material.

Embodiment 2

[0018] Embodiment 2: The production method of the oil field sludge rubber filler is carried out according to the following steps: first, the oil field sludge is used as a raw material for wet pulverization, and secondly, it is screened through a 400-mesh to 800-mesh sieve by a wet method, and the oil is heated at 105° C. to 120° C. After drying at ℃ temperature for 1 hour to 3 hours, it is pulverized and passed through a 200-mesh sieve to obtain powdery oilfield sludge rubber filler.

Embodiment 3

[0019] Embodiment 3: This natural rubber product is composed of the above-mentioned oil field sludge rubber filler as one of the raw materials and is composed of: 100 parts of natural rubber, 3 to 5 parts of zinc oxide, 1 to 2 parts of stearic acid, N- Cyclohexyl-2-benzothiazole sulfenamide 0.5 to 1.0 parts, dibenzothiazole disulfide 0.5 to 1.0 parts, sulfur 1.6 to 2 parts, oilfield sludge rubber filler 60 to 80 parts, kaolin 20 parts to 10 parts, 2,2,4-trimethyl-1,2dihydroquinoline 1 to 2 parts, N-isopropyl-N-phenyl-p-phenylenediamine 1 to 2 parts, aromatic oil 5 to 10 servings. The experimental results show that the filling effect of oilfield sludge filler and light calcium carbonate is similar, and the material is fast and does not fly during mixing. The tensile strength of the vulcanizate can reach 15-20Mpa, and the resilience can reach 60-70% , The tear strength can reach, 30 ~ 35Mpa, these properties are better than the properties of light calcium carbonate filler.

Abstract

The invention discloses oilfield sludge rubber filler, as well as a preparation method and a rubber product thereof. The oilfield sludge rubber filler is made by taking oilfield sludge as a raw material, and the oilfield sludge is made into the powdered oilfield sludge rubber filler with a grain size smaller than 200 meshes and water content smaller than 0.5%. The oilfield sludge rubber filler helps solve the problem of solid waste discharge of the oilfield sludge, thus achieving the purpose of protecting the environment; meanwhile, the oilfield sludge rubber filler provides a new cheap filler for the rubber industry, thus reducing material cost of the rubber product; and mineral oil in the sludge filler can reduce use amount of a softener in a formula of a rubber material, thus further reducing the material cost. Compared with light calcium carbonate filler, the rubber product can obtain certain more excellent performances than those of the rubber product made by the light calcium carbonate after applying the oilfield sludge rubber filler, such as processability, tensile strength, abrasion resistance, tear strength and rebound elasticity of rubber mixings. The oilfield sludge rubber filler has enormous economic benefit, social benefit and environmental benefit.

Description

technical field [0001] The invention relates to the technical field of oilfield sludge used in rubber, and relates to an oilfield sludge rubber filler, a production method and a rubber product. Background technique [0002] Oilfield sludge is a by-product of oilfield sewage treatment in the process of oil extraction. In order to improve the water treatment and anticorrosion effect in the sewage treatment after crude oil dehydration, a large amount of calcium, magnesium, sodium, potassium and other alkaline substances are added to the water quality. , resulting in a large amount of oily sludge with complex components. Its main components are calcium carbonate, clay, other silicon-alumina substances and mineral oil. [0003] The treatment and application of oily sludge in oilfields is a difficult problem to solve in the process of oilfield environmental protection. At present, the main methods of treating oily sludge at home and abroad are: natural drying method, concentrati...
