Abstract

The invention relates to a preparation process of an inorganic modified fire-proof plate and relates to the field of thermal insulation materials. The preparation process comprises the following steps: (1) stirring 100 parts of magnesium oxide, 40 parts of magnesium sulfate, 1 part of a modifying agent, 1 part of a foaming agent, 2 parts of a waterproof agent, 40 parts of water and 8 parts of a binding agent to a sizing agent by using a stirring pot; (2) placing 15 parts of polystyrene granule in a stirring machine, and then adding the stirred sizing agent of the step (1) to the stirring machine to uniformly stir for 2 minutes with the polystyrene granule; (3) adding the material stirred by the stirring machine in the step (2) to a mould, and then vibrating to compact; and (4) pressing a cover, placing in a steam pot to steam for 10-15 minutes at the temperature of 100 DEG C, naturally cooling to room temperature, and then demoulding. The inorganic modified fire-proof plate processed by the process has excellent thermal insulation properties, does not flow, is not burnt, does not generate a harmful gas when encountering high temperature or firing, has certain strength and tenacity, and is an efficient, environment-friendly, energy-saving and thermal-insulated material.

Description

A kind of inorganic modified PLASTIC LAMINATED preparation technology

Technical field

The present invention relates to field of heat insulating materials, is a kind of inorganic modified PLASTIC LAMINATED preparation technology specifically.

Background technology

Warming plate, also known as lagging material, as a kind of inside and outside wall thermal insulation, heat insulating function, is applicable to the fields such as residential building, office building, villa, hotel, apartment, hospital, market, school, Animal Raising Zone more, also can be used for the field such as interior wall partition, anti-fire door core board.What the lagging material on current market was conventional has polystyrene thermal insulation plate, polystyrene thermal insulation plate it there is good insulation, heat-proof quality, there is good easy act and shaping construction technology, and add fire retardant can play from fire from the fire-proof function put out, but once presence of fire, it will be the arch-criminal of disaster: one is the trickling of polystyrene pyrolytic decomposition, and oiliness trickling material is highly combustible, and plays the combustion-supporting effect of " adding fuel to the flames "; Two be add from fire from put out fire retardant decompose produce toxic gas, cause topsoil, threaten the life security of personnel in the scene of a fire.

Summary of the invention

In order to overcome the shortcoming that above-mentioned prior art exists, the object of the present invention is to provide a kind of inorganic modified PLASTIC LAMINATED preparation technology, the excellent thermal insulation performance of the inorganic modified warming plate of this processes, chance high temperature or baked wheaten cake do not trickle, do not burn, do not produce obnoxious flavour, skeleton is fine and close, have certain intensity and toughness, is the material of a kind of high-efficiency environment friendly, energy-saving heat preserving.

In order to solve the problem, the present invention by the following technical solutions: a kind of inorganic modified PLASTIC LAMINATED preparation technology, is characterized in that, comprise the following steps:

1) 100 parts, magnesium oxide, 40 parts, magnesium sulfate, properties-correcting agent 1 part, whipping agent 1 part, water-resisting agent 2 parts, 40 parts, water, 8 parts, tackiness agent are mixed slurry with stirred pot;

2) granules of polystyrene 15 parts is put into stirrer, then step 1) in the slurry that is stirred be added in stirrer with granules of polystyrene uniform stirring 2 minutes;

3) by step 2) in the material mixed of stirrer add in mould, then carry out concussion compacting;

4) press lid, put into steam-cured 10-15 minute at vapor can temperature 100 degree, naturally cool to room temperature, then the demoulding.

The invention has the beneficial effects as follows:

1, the excellent thermal insulation performance of the inorganic modified warming plate of this processes, meets high temperature or burns and do not trickle, do not burn, do not produce obnoxious flavour, and skeleton is fine and close, have certain intensity and toughness, is the material of a kind of high-efficiency environment friendly, energy-saving heat preserving.

Embodiment

A kind of inorganic modified PLASTIC LAMINATED preparation technology, is characterized in that, comprise the following steps:

1) 100 parts, magnesium oxide, 40 parts, magnesium sulfate, properties-correcting agent 1 part, whipping agent 1 part, water-resisting agent 2 parts, 40 parts, water, 8 parts, tackiness agent are mixed slurry with stirred pot;

2) granules of polystyrene 15 parts is put into stirrer, then step 1) in the slurry that is stirred be added in stirrer with granules of polystyrene uniform stirring 2 minutes;

3) by step 2) in the material mixed of stirrer add in mould, then carry out concussion compacting;

4) press lid, put into steam-cured 10-15 minute at vapor can temperature 100 degree, naturally cool to room temperature, then the demoulding.

The excellent thermal insulation performance of the inorganic modified warming plate of this processes, meets high temperature or burns and do not trickle, do not burn, do not produce obnoxious flavour, and skeleton is fine and close, have certain intensity and toughness, is the material of a kind of high-efficiency environment friendly, energy-saving heat preserving.

The present invention is not only confined to above-described embodiment.
