Problems solved by technology

[0003] The purpose of the present invention is to overcome the unsaturated polyester resin glass fiber molded parts in the above-mentioned prior art with large mechanical strength dispersion, poor weather resistance, water resistance and oil resistance, and the resin is easily degraded under natural environmental conditions to cause material strength. The rapid reduction of the rapid reduction can not meet the shortcomings of its service life requirements of more than 10 years under outdoor natural conditions. It provides a stable mechanical strength, small dispersion, good weather resistance, good hydrolysis resistance, good oil resistance, and resistance to water. Aircraft arresting bed arresting unit top cover with high combustion performance and low shrinkage rate and preparation method thereof

preparation example Construction

[0025] The preparation of the non-metallic protective roof is to cut the above-mentioned SMC material into the required size according to the process requirements and remove the supporting films on both sides, and lay them in layers according to the required thickness of the product and press them into the roof mold at 140-150 °C. , Hot pressing process conditions: mold temperature 140 ~ 150 ℃, pressure 10 ~ 11MPa, holding time 100 ~ 110sec. Take it out after hot pressing, and let it cool down to room temperature naturally, and then you can make a non-metallic protective top cover.

[0026] The weight composition of the non-metal protective top cover is: 15-25 parts by weight of dicyclopentadiene type unsaturated polyester resin, 5-8 parts by weight of styrene solution of 40% polybutadiene-styrene copolymer resin, 5-25 parts by weight of 8 parts by weight of styrene solution of 40% polyvinyl acetate, 55-65 parts by weight of aluminum hydroxide, 3-5 parts by weight of ultraviol...

Embodiment 1

[0028] 68% of 20kg can thicken the styrene solution of dicyclopentadiene modified unsaturated polyester resin, the 40% polybutadiene-styrene copolymer resin styrene solution of 7kg, the 40% polyvinyl acetate benzene of 6kg Ethylene solution, 60kg aluminum hydroxide, 4kg parts by weight ultraviolet absorber, 0.5kg active magnesium oxide, 0.5kg benzopinacol silyl ether, 1.2kg titanium dioxide pigment paste, 0.8kg zinc stearate Put it into a mixing tank at room temperature and stir at high speed for 10 minutes to prepare 100kg of resin paste. Then the SMC material with 10% chopped glass fiber content is made on the SMC unit.

Embodiment 2

[0030] 68% of 15kg can thicken the styrene solution of dicyclopentadiene modified unsaturated polyester resin, 8kg of 40% polybutadiene-styrene copolymer resin styrene solution, 8kg of 40% polyvinyl acetate benzene Ethylene solution, 62kg aluminum hydroxide, 4kg parts by weight ultraviolet absorber, 0.5kg active magnesium oxide, 0.5kg benzopinacol silyl ether, 1.2kg titanium dioxide pigment paste, 0.8kg zinc stearate Put it into a mixing tank at room temperature and stir at high speed for 10 minutes to prepare 100kg of resin paste. Then the SMC material with 10% chopped glass fiber content is made on the SMC unit.

Abstract

The invention provides an airplane blocking bed blocking unit top cover and a preparation method thereof, and aims to provide the airplane blocking bed blocking unit top cover which is stable in mechanical strength, low in dispersity, high in weather resistance, and high in flame retardant property. Through the technical scheme, dicyclopentadiene type unsaturated polyester resin is adopted as matrix resin, a polybutadiene-styrene copolymer is adopted as a low shrinkage agent, benzopinacole silicon alkyl ether is respectively or commonly used with benzoyl peroxide tert-butyl ester, peroxide-2-ethylhexoic acid tert-butyl ester to form an initiator, an unsaturated polyester glass fiber modeling piece SMC prepared from an ultraviolet absorbent is added, then the SMC resin paste is used for steeping and rolling an upper resin paste film layer, a middle chopped glass fiber layer and a lower resin paste film layer through a coating machine, and the SMC material containing 8 to 12 parts by weight of chopped glass fiber is prepared through curing; and then the product is molded through compression and cooled to room temperature in a laminated top cover mold with required thickness.

Description

technical field [0001] The invention relates to a preparation method and molding process of an unsaturated polyester glass fiber sheet molding compound (SMC) applied to a non-metallic protective roof of an airport arresting system device, and can also be applied to electrical equipment, mechanical structures, and vehicles Components, transportation facilities, mining, construction, and office life and leisure fields. Background technique [0002] The aircraft arresting system is an important security facility at the airport. It implements safety arrests on aircraft that frequently land or accidentally run off the runway to ensure the safety of man and machine. The design of the arresting system directly affects the changes in aircraft overload, safe arresting distance, belt pull, and brake pressure, and ultimately affects the arresting effect. At present, foreign blocking equipment is developing rapidly, and the research in this area is relatively mature. Due to the confide...
