Straw glass fiber fireproof plate section and preparation method thereof

Abstract

The invention discloses a straw glass fiber fireproof plate section which is characterized by being prepared from the following raw materials in parts by weight: 70-80 parts of crop straws, 3-5 parts of glass fibers, 7-9 parts of a phenolic resin, 4-5 parts of polyurethane, 2-3 parts of zinc borate, 1-2 parts of ammonium polyphosphate, 1-1.5 parts of rosin, 0.4-0.6 part of sodium pyrithione and 10-12 parts of a synergetic filler. The crop straws are taken as a base material of the plate, and the glass fibers, zinc borate and the like are added, so that the fireproof plate section is heat-resistant and flame-retardant; due to the addition of the rosin and sodium pyrithione, insect prevention and rotting protection are realized; due to dual effects of the phenolic resin and polyurethane, the defect that the glass fibers are low in wear resistance is overcome; due to the addition of a modifier prepared by a special process, the flame-retardant property, toughness and wear resistance are further improved; and moreover, the strength of the prepared plate exceeds that of solid wood, fire resistance, moth resistance, rotting protection and moisture prevention are realized, three wastes are avoided in the production process, the amount of the wood is saved, air pollution caused by straw combustion is reduced, and income of the peasants is increased.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a straw glass fiber fireproof board profile and a preparation method thereof. Background technique [0002] my country is a large agricultural country with abundant straw resources. Most of the straw is burned, which pollutes the environment and also poses safety hazards. In recent years, under the encouragement of the government, the recycling of crop straw has been further developed. In addition to the traditional crushing and returning to the field and processing feed, it is also used for papermaking and building decoration materials. [0003] In recent years, there have been examples of comprehensive utilization of straw, such as applying straw boards to decorative boards, etc., but most of the decorative boards are made of a mixture of organic materials and straw powder, which have poor fire resistance, or the process is too cumbersome , do not utilize industrial productio...
