Abstract
The invention relates to a shock resistant and stretch proof plastic containing dimethyl silicone rubber. The plastic comprises the following components: by weight, 70-80 parts of the dimethyl silicone rubber, 50-60 parts of furfural acetone resin, 10-20 parts of propylene glycol, 10-20 parts of limestone powder, 10-20 parts of asbestos, 10-20 parts of polypropylene, and 10-20 parts of magnesium stearate. The prepared plastic containing the dimethyl silicone rubber has good shock-resistant and stretch-proof effects.
Description
Technical field
The present invention relates to a kind of Shock-resistant stretch-proof plastic cement, particularly relate to a kind of Shock-resistant stretch-proof plastic cement containing dimethyl silicone rubber.
Background technology
Develop rapidly along with manufacturing both at home and abroad, the relevant chemical industry such as plastic plastics have also been obtained fast development and renewal.Along with the demand of user to plastic cement is more and more wider, user is also also more and more tighter to the quality criteria requirements of plastic cement simultaneously.Relating to the professional domain of Shock-resistant stretch-proof plastic cement, as on some electron devices and wear resistant appliance to the requirement of Shock-resistant stretch-proof plastic cement height very, the plastic cement kind simultaneously in the market with shock resistance and stretch-proof effect is less, can not meet market demand, therefore developing a kind of plastic cement simultaneously with good Shock-resistant stretch-proof is to meet large market needs.
Summary of the invention
The technical problem solved: conventional plastic shock resistance and the poor problem of stretch-proof effect.
Technical scheme: the present invention is a kind of Shock-resistant stretch-proof plastic cement containing dimethyl silicone rubber, is made up of: dimethyl silicone rubber 70 ~ 80 parts, furfural acetone resin 50 ~ 60 parts, propylene glycol 10 ~ 20 parts, limestone powder 10 ~ 20 parts, 10 ~ 20 parts, asbestos, polypropylene 10 ~ 20 parts, Magnesium Stearate 10 ~ 20 parts following composition according to weight ratio.At 80 DEG C, various composition is dropped into reaction vessel allotment, stir, be heated to 150 DEG C and keep 8h, the plastic cement with good Shock-resistant stretch-proof effect after cooling, can be obtained.
Beneficial effect: after preparing the Shock-resistant stretch-proof plastic cement containing dimethyl silicone rubber, its shock resistance and tensile property are tested.Adopt the shock resistance of ASTMD256 standard to plastic cement to test, result shows the Shock-resistant stretch-proof plastic cement containing dimethyl silicone rubber that the present invention makes, and shock resistance is 280 ~ 290J/M, has good shock resistance.Plastic cement is under GB/T1040-2006 standard in addition, and the Shock-resistant stretch-proof plastic cement tensile property containing dimethyl silicone rubber is 70 ~ 75Mpa, has good shock resistance and stretch-proof characteristic.
Embodiment
Preparation method is as follows for Shock-resistant stretch-proof plastic cement products: first by retort temperature modulation 80 DEG C, various composition is dropped in retort successively, do not stop to stir, treat post-heating to the 150 DEG C maintenance 8h that thoroughly stirs, after cooling, obtain the Shock-resistant stretch-proof plastic cement containing dimethyl silicone rubber.Shock resistance test employing method is ASTMD256 standard, and stretch-proof test employing method is GB/T1040-2006 standard.
Embodiment 1
Preparation method as previously mentioned, fills a prescription as following composition forms according to weight: dimethyl silicone rubber 80kg, furfural acetone resin 60kg, propylene glycol 20kg, limestone powder 20kg, asbestos 20kg, polypropylene 20kg, Magnesium Stearate 20kg.This plastic cement shock resistance result is 290J/M, has good shock resistance.Tensile property is 75Mpa, has good stretch-proof characteristic.
