A kind of eps flame-retardant fire-proof board and its production process

Abstract

The invention relates to an EPS flame-retarding and fireproof plate and a production technology thereof. The EPS flame-retarding and fireproof plate employs EPS particles, melamine resin, aluminium hydroxide and borax as raw materials, which are mixed according to a certain weight ratio and are subjected to a mixing and stirring process, a pressing and molding process, a mold-detaching and storing process, a cutting process and a packaging process to obtain the EPS flame-retarding and fireproof plate. The beneficial effects of the plate are that waste foam materials are employed as aggregate materials so that white pollution is eliminated; a steam boiler needs not to be installed so that pollution discharge is avoided and the production technology is energy-saving and environmental-friendly; waste can be turned into wealth and processes of the production technology are little so that production cost is reduced; and the plate is free from formaldehyde and organic solvents and is free of toxicity and radioactive substance so that the plate has no influences on environment and health of human body and mind. The production technology replaces a conventional thermoplastic molding technology and a conventional thermoset molding technology and is a revolutionary transformation in heat-insulation manufacturing industry.

Description

(1) Technical field [0001] The invention belongs to the technical fields of high fire resistance, heat preservation, heat insulation and environmental protection, and in particular relates to an EPS flame retardant fireproof board suitable for building wall heat preservation, military manufacturing, train ships, cold storage, aircraft and aerospace, etc. and its production It can achieve the purpose of safety, fire prevention, heat preservation and energy saving. (2) Background technology [0002] The existing EPS insulation board molding technology is molded by thermoplastic technology, and its products are difficult to meet the requirements of the national fire rating standard, and can only reach B in the fire rating 2 、B 3 grade, difficult to achieve B 1 Class requirements, but restricted by the state. [0003] In recent years, a thermosetting molding technology introduced from abroad has been monopolized by foreign countries (including raw materials) due to difficulty...

AI Technical Summary

Problems solved by technology

However, the existing technology cannot reduce its cubic density, resulting in high thermal conductivity and loss of its thermal insulation performance

The comprehensive technical indicators are difficult to meet the requirements of the national energy-saving standards, and relevant experts have pointed out that the product contains a large amount of magnesium chloride and has anti-halogen phenomenon, which cannot fundamentally solve the technical bottleneck

It cannot be used for permanent building and external wall insulation, which will greatly reduce the development prospects of the product!

[0007] For this molding technology, ordinary Portland cement was used for wrapping. Although the anti-halogen phenomenon in the product was solved, the cubic density of the product was far from 200kg to meet the strength required by the national standard, which caused the thermal conductivity to be seriously high and difficult to achieve. National 75% energy saving standard

[0008] Because it is wrapped with ordinary Portland cement, it is spontaneously combusted and solidified, and the curing time period is long. Generally, it takes one to 10 days to remove the mold and cut it. The product turnover period is too long and the production capacity is low, which is not conducive to large-scale production and large-scale production. Area promotion
