Embodiment 1

[0031] Under the condition of 50±10°C, 0.1% by mass percentage of styrene-butadiene rubber is dissolved in dicyclopentadiene with a purity of more than 98% and a mass percentage of 99.9%, and the dicyclopentadiene-styrene-butadiene rubber solution is obtained after uniform stirring. The obtained dicyclopentadiene styrene-butadiene rubber solution is subjected to degassing reaction and then protected with an inert gas for use.

[0032] Under nitrogen protection, 20 kg of dicyclopentadiene styrene-butadiene rubber solution (40 kg in total, containing 0.04 kg of styrene-butadiene rubber) was added to feed tank A and feed tank B of the reaction injection molding machine respectively. Because the catalyst of this system is easy to lose activity when it encounters water vapor and air, the whole system must be sealed and protected by inert gas.

[0033] Add 0.0002 kg of tert-butyl hydroperoxide (1% of the contained rubber mass) and 0.107 kg of bis[2,6 di-tert-butyl-4-methylphenoxy] t...

Embodiment 2

[0038]Under the condition of 50±10°C, dissolve styrene-butadiene rubber with a mass percentage of 1% in dicyclopentadiene with a purity of more than 98% and a mass percentage of 99%, and stir evenly to obtain a dicyclopentadiene-styrene-butadiene rubber solution. The obtained dicyclopentadiene styrene-butadiene rubber solution is degassed and then protected with inert gas for use.

[0039] Under nitrogen protection, 20 kg of dicyclopentadiene styrene-butadiene rubber solution (40 kg in total, containing 0.4 kg of styrene-butadiene rubber) was added to feed tank A and feed tank B of the reaction injection molding machine respectively. Because the catalyst of this system is easy to lose activity when it encounters water vapor and air, the whole system must be sealed and protected by inert gas.

[0040] Add 0.005 kg of tert-butyl hydroperoxide (2.5% of the contained styrene-butadiene rubber mass) and 0.106 kg of bis[2,6 di-tert-butyl-4-methylphenoxy] dichloride in A material tank...

Embodiment 3

[0045] Under the condition of 50 DEG C, 10 mass percent of styrene-butadiene rubber is dissolved in dicyclopentadiene with a purity of more than 98 percent and a mass percent of 90 percent, and the dicyclopentadiene-styrene-butadiene rubber solution is obtained after uniform stirring. The obtained dicyclopentadiene styrene-butadiene rubber solution is degassed and then protected with inert gas for use.

[0046] Under nitrogen protection, 20 kg of dicyclopentadiene styrene-butadiene rubber solution (40 kg in total, containing 4 kg of styrene-butadiene rubber) was added to feed tank A and feed tank B of the reaction injection molding machine respectively.

[0047] Add 0.1 kg of tert-butyl hydroperoxide (5% of the contained styrene-butadiene rubber mass) and 0.096 kg of bis[2,6-di-tert-butyl-4-methylphenoxy] dichloride in A material tank Tungsten catalyst (1 / 2000 of the molar number of dicyclopentadiene added).

[0048] Add 0.656 kg of diethylaluminum chloride (40 times the mo...

Abstract

The invention provides a preparation method of a polydicyclopentadiene/rubber in-situ polymerization blending composite material. The method comprises the following steps: dissolving the rubber into the polydicyclopentadiene, taking the aryloxy-tungsten complexes as main catalyst and the alkyl aluminium as cocatalyst, utilizing reaction injection molding technology to prepare the polydicyclopentadiene/rubber blending composite material by in-situ polymerization blending, due to the introduction of the rubber, the polydicyclopentadiene material has high toughness, thus enlarging the application field thereof. By adopting the reaction injection molding method, a high performance polydicyclopentadiene composite material can be prepared simply and effectively. The prepared polydicyclopentadiene/rubber in-situ polymerization blending composite material has higher impact resistant performance of which the impact strength can reach 200-400J/m.

Description

technical field [0001] The invention belongs to the technical field of polymer composite materials, and in particular relates to a method for preparing a polydicyclopentadiene / rubber in-situ polymerization blending composite material. Background technique [0002] Polydicyclopentadiene (English abbreviation PDCPD) is an engineering plastic with high impact strength and high flexural modulus.
