Environment-friendly type extruded plastic board and preparation method thereof

Abstract

The invention relates to an environment-friendly type extruded plastic board and a preparation method thereof. The board comprises the following raw material components in parts by weight according tothe proportion: 60-80 parts of polystyrene resin, 20-30 parts of epoxy resin, 10-15 parts of white carbon black, 10-15 parts of hollow glass beads, 5-8 parts of calcium carbonate, 6-7 parts of silicon carbide, 4-8 parts of tetrafluorodichloroethane, 3-5 parts of coconut diethanolamide, 6-10 parts of deionized water, and 10-20 parts of argon gas. The product has the advantages of easily availablematerials, low cost, environmental protection and green, uniform dispersibility of internal structure, large foam volume, large density, good insulation effects, excellent sound insulation effects, good fire protection ability, portable quality, transport and installation convenience, saved manpower, reduced cost, good stability, good anti-compression capability, good insulation effects, and certain antivibration effects.

Description

Technical field [0001] The invention relates to the field of boards, in particular to an environmentally friendly extruded board and a preparation method thereof. Background technique [0002] With the development of economy and society, saving energy and protecting the environment have become the consensus of mankind, and reducing energy consumption has become the goal of human joint efforts. In order to save energy more effectively, energy-saving buildings have become an important topic. Improving the insulation performance of buildings can have a significant effect on the energy consumption caused by air conditioning. Therefore, the building’s use of high-performance thermal insulation materials Demand has also increased. [0003] In thermal insulation materials can be roughly divided into two categories, one is organic polymer materials, the other is inorganic materials, organic polymer materials such as extruded polystyrene insulation board due to its light weight, thermal in...

AI Technical Summary

Problems solved by technology

[0003] In heat insulation materials, it can be roughly divided into two categories, one is organic polymer materials, and the other is inorganic materials. Well, it has been increasingly widely used in the building materials industry as a thermal insulation board, and inorganic thermal insulation materials have the characteristics of good economy, high compression modulus, and good flame retardancy, but inorganic thermal insulation materials have the characteristics of heavy weight and high water absorption. , brittle and easily broken

Therefore, some operators compound organic materials and inorganic materials, but the thermal insulation building material board after the two are compounded has problems in thickness, and at the same time, it cannot reflect the light texture of organic polymer materials, so that it is actually used in construction. There are many inconveniences

[0004] In addition, in the traditional polystyrene board manufacturing method, various raw materials are added one by one and then stirred. In order to stabilize the quality of the subsequent polystyrene board, it usually needs to be stirred for a certain period of time so that all raw materials are fully and evenly mixed. However, this method takes a long time during the mixing process, which has a great impact on production capacity
