Embodiment

[0069] Composition of the resin mixture

[0070] Based on the total weight of the resin composition, the ratio of the resin composition is: 36% of 199-type m-benzene unsaturated polyester resin, 20% of basalt fiber cloth, 13% of basalt fiber grid (50mm×50mm), 13% of glass fiber short Cut mat 3%, basalt rock particles (3mm) 20%, flame retardant (aluminum hydroxide) 3%, cobalt naphthenate 2%, methyl ethyl ketone peroxide 3%.

[0071] Manufacture of doors

[0072] First, fully stir the 199-type unsaturated polyester resin, cobalt naphthenate, and flame retardant aluminum hydroxide according to the proportion to obtain the unsaturated polyester resin premix.

[0073] The surface of the mold with the groove in the shape of the ring insert is treated with mold release water, and the locks and hinges are placed in the predetermined positions. Then spray gel coat resin (8300g-1, DSM) on its surface. Before painting, add the curing agent methyl ethyl ketone peroxide in the above pro...

Abstract

The invention relates to a resin composition for a civil air defense door, a door leaf prepared from the resin composition, a method for manufacturing the door leaf, and the civil air defense door. The resin composition comprises: 30 to 40 percent of unsaturated polyester resin, 18 to 25 percent of basalt fiber fabric, 10 to 15 percent of basalt fiber grid, 3 to 5 percent of glass fiber felt, 20 to 30 percent of basalt rock particles, 3 to 5 percent of flame retardant and 1 to 5 percent of curing agent, wherein the thermal deformation temperature of the unsaturated polyester resin is more than or equal to 110 DEG C, and the tensile strength is greater than or equal to 50 MPa. The civil air defense door has the advantages of light weight, high strength and corrosion resistance and has good insulation property, sound insulation property and flame retardancy.

Description

technical field [0001] The invention relates to a resin composition for civil air defense doors based on unsaturated polyester resin, a door leaf made of the resin composition, a preparation method of the door leaf, and a civil air defense door comprising the door leaf. Background technique [0002] At present, civil air defense equipment products are mainly reinforced concrete composite structures and steel structures, and such products have been widely used in the market. However, civil air defense products made of steel bars and concrete are heavy, and the transportation and installation process is relatively difficult. Moreover, the production process of steel bars and concrete consumes a lot of energy and causes serious pollution to the environment. [0003] With the development of composite material technology, new composite materials have advantages that concrete and steel do not have, such as relatively heavy weight and good insulation, sound insulation and flame re...
