Problems solved by technology

[0006] The present invention provides a nano-calcium filler technology for nitrile raw materials, one of which is to have the ability to improve the toughness and strength of nitrile rubber, and to solve the problem that nitrile rubber itself has poor impact resistance and insufficient toughness, and cannot be used during use. Better transmission of external stress, poor compatibility between particles and the matrix; another purpose is to solve the problem that some harmful substances will be produced due to the different mixing degrees between the production process and various materials, and the harmful substances remain in the The interior of the material greatly affects the safety of the material used, in order to improve the environmental protection of nitrile rubber and reduce the manufacturing cost of nitrile rubber

Embodiment 1

[0033] Such as figure 1 Shown, the present invention provides a kind of nitrile raw material nano-calcium filler technology, this nitrile raw material nano-calcium filler technology, comprises the following steps:

[0034] Step 1, preparing nano-calcium carbonate suspension;

[0035] Step 2, mixing of nitrile rubber and suspension;

[0036] Step 3, dry vulcanization, modification molding;

[0037] Step 4, compress into thin slices.

[0038] In this example, through the mixing of nano-calcium carbonate suspension and nitrile rubber, a more stable and simple preparation method is provided for the strength and toughness of nitrile rubber, and the preparation of modified molding by dry vulcanization The process can accelerate the speed of material preparation, ensure the environmental protection of material production, and further improve the efficiency of material preparation.

Embodiment 2

[0041] Such as figure 1 Shown, on the basis of embodiment 1, the present invention provides a kind of technical scheme: preferably, step 2 also includes: nitrile rubber adopts rubber latex to make, and the composition of rubber latex is 40% natural latex An organic compound formed by combining 35 percent nitrile latex and 25 percent polybutadiene latex, by utilizing the similar material properties of natural latex, nitrile latex and polybutadiene latex , so that its mixing rate and compatibility are higher, and the proportion of natural latex is matched to ensure the environmental protection performance of rubber latex. The mixing of nitrile rubber and suspension needs to add gelling agent. The gelling agent is gelatin and casein acid One or two of sodium, gum arabic, agar, xanthan gum, and gellan gum, and the addition of various natural organic gelling agents can not only increase the viscosity of the material mixture, but also ensure that it is in an emulsified state , and ...

Embodiment 3

[0043] Such asfigure 1 As shown, on the basis of Example 1 and Example 2, the present invention provides a technical solution: preferably, step 3 also includes: a vulcanization activator needs to be added in the dry vulcanization process, and the composition of the vulcanization activator is a vulcanization accelerator M, and the proportion of the vulcanization accelerator M is 0.5% of the total amount of the nitrile rubber and the suspension. Through the action of the vulcanization accelerator M, the vulcanization speed of the preparation process is accelerated, and the strength and stability of the material are improved. At the same time, the vulcanization accelerator M itself has both anti-aging and peptizing effects, which can add subsidiary attributes to the material and improve the product performance of the material. During the drying and vulcanization process, it is necessary to add activated carbon with a ratio three times that of the vulcanization accelerator M, that i...

Abstract

The invention discloses a butyronitrile raw material nano calcium filling material technology, and relates to the technical field of chemical material preparation, and the butyronitrile raw material nano calcium filling material technology comprises the following steps: preparing nano calcium carbonate turbid liquid, mixing nitrile rubber and the turbid liquid, drying and vulcanizing, modifying and forming, and pressing into sheets; wherein, the nano calcium carbonate turbid liquid is prepared by mixing calcium carbonate powder and a calcium hydroxide solution, and dispersing agents need to be added at equal intervals in the preparation process of the nano calcium carbonate turbid liquid. By mixing the calcium carbonate powder and the calcium hydroxide solution to prepare the nano calcium carbonate turbid liquid, when the nano calcium carbonate turbid liquid is mixed with the nitrile rubber, the impact resistance of the nitrile rubber can be improved, meanwhile, the obvious defects such as toughness of the nitrile rubber are overcome, and the problems of poor impact resistance of nitrile rubber, insufficient toughness, inability to transfer external stress during use, and poor compatibility between particles and a matrix are solved. the utilization efficiency of the nitrile rubber is improved, and the use field of the nitrile rubber is expanded.

Description

technical field [0001] The invention relates to the technical field of chemical material preparation, in particular to a process for a nitrile raw material nano-calcium filler. Background technique [0002] Nano-calcium carbonate is a new type of ultra-fine solid powder material with a particle size between 0.01 and 0.1 μm. Due to the ultra-fine size of nano-calcium carbonate particles, its crystal structure and surface electronic structure change, resulting in the formation of ordinary calcium carbonate. It does not have quantum size effect, small size effect, surface effect and macroscopic quantum effect, while nitrile rubber is a copolymer made of acrylonitrile and butadiene monomer, which is mainly produced by low temperature emulsion polymerization. It is poor low temperature resistance, poor ozone resistance, poor insulation performance, and slightly lower elasticity, so a new product process is needed to improve the various properties of nitrile raw materials.
