Problems solved by technology

The hematilite used in this application has only been pulverized without modification, and its surface adsorption capacity is not strong enough to be easily filled into the network structure of vulcanized rubber, and the rubber cannot enter more and more fully into the hematite. In the holes and channels of the rubber, the effect on the processing performance and physical properties of the rubber is not large enough

Embodiment Construction

[0011] Using the hematilite ore produced in Ziyuan County, Guangxi as the main raw material, the raw ore was washed, crushed and processed to 60-80 mesh, and 60g of hematite was modified by soaking in 120ml of 5% hydrochloric acid solution for 40 minutes. After modification Neutralize with 5g of calcium oxide, filter and wash until the pH value of the solution is 6.5, and dry the powder until the water content is less than 1%, to obtain the modified hematilite.

Abstract

The invention relates to a modified epidesmine rubber reinforcement additive and preparation method thereof, which is made from epidesmine raw ore processed by washing, crashing, hydrochloride immersion, calcium oxide neutralization, washing, drying and packing. The advantages of the invention are specific surface and compatibility of the epidesmine are improved after being modified, surface adsorbing power are enhanced, the epidesmin is easy to fill in the rubber mesh organization, the rubber is easier to get into the bee-like structure, and the processing performance and physical property of the rubber can be enhanced. The rubber reinforcement made from the additive has tension strength at break which is increased from 7.23MPa to 10.6MPa, even higher, and hardness from 76 to 82,.

Description

Technical field: [0001] The invention relates to the application of hematilite, in particular to the modified hematilite rubber reinforcing additive and its preparation method. Background technique: [0002] Stellerite is a mineral species in the zeolite family, its chemical composition (%): SiO 2 : 58.76, Al 2 o 3 : 14.13, CaO: 8.80, K 2 O: 0.11, Na 2 O: 0.18, Fe 2 o 3 : 0.44, H 2 o + : 16.87, H 2 o - : 1.25, natural staphilite is a kind of hydrous alkali metal or alkaline earth metal aluminosilicate mineral of natural zeolite. It is a framework silicate composed of silicon-oxygen tetrahedron and aluminum-oxygen tetrahedron. In addition, zeolite has a special structure, rich holes and channels, accounting for about 40-50% of the total volume, and has multiple uses. The applicant of this case once applied to the Chinese Patent Office on June 14, 2005 for the "preparation method of natural hematite as a rubber reinforcing additive". Carry out elutriation, pulveriz...
