Problems solved by technology

Due to the disadvantages of unsaturated polyester, such as poor toughness, low strength, easy burning and large shrinkage, the scope of its application in building panels is limited.
In the prior art, people use various excellent characteristics of artificial stone materials to compound with other materials such as ceramic substrates, cement concrete substrates, wood substrates, plastics and other organic material substrates to obtain composite panels that have the advantages of composite substrates. The composite method Both artificial stone panels and substrates of other materials are bonded together with adhesives. The problems in this method are: the joint is not firm, and the product will be degummed when it is rapidly cooled or heated or in the presence of water. The phenomenon of hollowing; fire prevention, noise prevention, and corrosion resistance are poor, and the sound insulation and fire prevention effects cannot be achieved when used in buildings, which limits its scope of use.

Abstract

Low-shrinkage unsaturated polyester resin / concrete composite plate and its preparation method, 30-35 parts of aluminate cement, 10-20 parts of natural aggregate, 20-30 parts of resin aggregate, 40-45 parts of glass microspheres; preparation method As follows: first mix unsaturated polyester resin, nano-silver antibacterial agent, filler, low-shrinkage agent, diluent, and initiator to prepare resin aggregate, and mix it with natural aggregate and glass beads evenly, and then pour it into the mold Spread a layer of cement slurry and glass fiber mesh Ⅰ, then spread the aggregate mixture on the glass fiber mesh Ⅰ, spread the glass fiber mesh Ⅱ after spreading, and then pour the remaining cement slurry on the glass fiber mesh Ⅱ , demoulding after standing for 24 hours, the light-weight low-shrinkage unsaturated polyester resin / concrete composite board can be obtained; Electrical insulation can guarantee the safety performance of use.

Description

technical field [0001] The invention relates to the field of unsaturated polyester resin, in particular to a low-shrinkage unsaturated polyester resin / concrete composite board and a preparation method thereof. Background technique [0002] Unsaturated polyester resin, a linear prepolymer formed by melting polycondensation of dihydric alcohol and unsaturated dibasic acid anhydride or unsaturated dibasic carboxylic acid, saturated dibasic anhydride or saturated dibasic carboxylic acid, under heating, light, Copolymerized with vinyl monomer under the action of radiation and initiator, cross-linked and cured into a thermosetting resin with network structure. Unsaturated polyester resins have many advantages, such as easy availability of raw materials, chemical corrosion resistance, and excellent electrical and mechanical properties. Unsaturated polyester resin has long attracted people's attention due to its excellent formability and good comprehensive performance. It is widely...
