Abstract

The invention discloses a manufacturing method for an external wall heat insulation board, and relates to the field of constructional engineering materials. The method includes the steps that A, the raw materials including, by weight, 40-60 parts of polystyrene, 20-30 parts of boron fibers, 12-18 parts of magnesium hydrate, 2-4 parts of antimonous oxide,1-3 parts of white carbon black, 1-2 parts of defoaming agent and 0.8-1.2 parts of lubricating agent are weighed; B, the raw materials are heated and evenly mixed, wherein the temperature ranges from 40 DEG C to 60 DEG C; C, the mixture is added into an extruder to be pelleted, wherein the pelleting temperature ranges from 160 DEG C to 200 DEG C; D, pellets obtained in the step C are dried and then added into an extrusion molding machine, the temperature is controlled to range from 180 DEG C to 190 DEG C, pressure ranging from 100 MPa to 120 MPa is applied in a mold and maintained for 1 min-2 min, and the mold is opened to take out the product after cooling. The method solves the problem that an existing external wall heat insulation board formed through extrusion molding is poor in flame resistance.

Description

technical field [0001] The invention relates to the technical field of construction engineering materials, in particular to a method for manufacturing an external wall heat insulation board. Background technique [0002] Thermal insulation board is a common material in the construction industry. It is mostly used for thermal insulation of roofs and walls of buildings to reduce indoor heat loss and achieve environmental protection and energy saving. The traditional method of making thermal insulation boards for external walls is mainly to mix slurry of cement and thermal insulation granular materials, which are poured on the wall to form an insulation layer. This kind of insulation board is heavy, and it is easy to fall off from the wall after a long time of use. Existing manufacturing methods of external wall thermal insulation boards have been developed in the direction of light weight. Extruded plastic thermal insulation boards are a common manufacturing method for lightwe...
