Modified plastic extruded board material and manufacture method of modified plastic extruded board

Abstract

The invention provides a modified plastic extruded board material, which is particles including graphite powder and a flame retardant in the ratio of 1:1.1-1.25. The invention also provides a manufacture method of a modified plastic extruded board by using the modified plastic extruded board material. The material mixed with polystyrene particles, a foaming agent and other additives can be produced into a plastic extruded board with high strength, high flame retardancy and high heat insulation; while the modified plastic extruded board has good stability and lighter texture, and usage of the modified plastic extruded board with thin thickness can achieve very good heat insulation effect and effectively reduce the weight of unit area of the board.

【Technical field】 [0001] The invention relates to a modified extruded board raw material and a method for manufacturing the modified extruded board, in particular to a modified extruded board raw material containing graphite flame retardant particles and a method for manufacturing a modified extruded board using the raw material . 【Background technique】 [0002] With the development of economy and society, saving energy and protecting the environment has 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 thermal insulation performance of buildings can have a significant effect on the energy consumption caused by air conditioning. Demand has also increased.

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

[0005] In addition, some people in the industry have proposed a method of making polystyrene boards from expanded graphite, which is to directly modify the expanded graphite and then mix and extrude it with polystyrene. However, in this manufacturing method, expanded graphite is mixed unevenly in polystyrene. problems, which in turn makes the final polystyrene board product structurally unstable due to uneven mixing of expanded graphite, which greatly affects the strength and durability of the polystyrene board
