Description
Technical field:
The present invention is relevant with heat insulating material for external surface of wall.
Background technology:
Existing external wall body thermal insulation material is as described in the patent application document of CN1458112 as publication number, is made by following weight percent proportion raw material: cement 50-55, granular polystyrene 10-15, flyash 20-25, light calcium carbonate 1-5, water-ground limestone 5-10, cellulosic fibre 0.1-0.5, methylcellulose gum 0.1-0.3, starch ethers 0.1-0.2, whipping agent 0.1-0.2, air entrapment agent 0-0.2.Above-mentioned dusty raw materials is hybrid packed.Because organic materialss such as granular polystyrene are difficult to be bonded to integral body with the inorganic materials body of wall, need with expensive binding agent or the auxiliary immovable bed of making wire netting, not only difficulty of construction is big, and the cost height also produces " heat bridge " effect, and heat insulation effect is reduced.After suffering fire, organic substance can discharge a large amount of toxic gases, and the disaster relief and disaster-stricken crowd are injured.Publication number is that the prescription of the Chinese patent application file of CN150075 is rubber powder material 88-92, granular polystyrene 8-12.The rubber powder material is cement 52-72, flyash 20-39, alkali proof fiber 0.24-1.2, Mierocrystalline cellulose 0.6-1.2, sepiolite 0-9.0, hard hydrochlorate 0-4.0, calcium oxide 0-4.0, calcium metasilicate 0-2.4.Granular polystyrene is to be pulverized by waste polystyrene foam to form.This external wall body thermal insulation material also has above-mentioned drawback.
Summary of the invention:
The purpose of this invention is to provide a kind of rejected material, with low cost, easy to manufacture, easy to use, high insulating effect, heat insulating material for external surface of wall free from environmental pollution of making full use of.
The present invention is achieved in that
Heat insulating material for external surface of wall of the present invention, it is to be made by the raw material of following weight part:

The present invention includes following steps:
(1) be equipped with waste paper fibre:
Earlier waste paper is pulverized the back with pulverizer and adds first agitation vat, add water, pulping agent, the fireproofing agent of 6～7 times of paper amounts simultaneously, stirred 5～10 minutes,, promptly get the paper fiber of tool fire performance then with the paper fiber drying,
When (2) preparing foaming agent, gelatinizing agent, water-resisting agent, fireproofing agent, activator, all commercial raw material is mixed getting final product by the prescription metering,
(3) prepare the powdery lagging material, waste paper fibre, thermal insulation light aggregate, flyash, cement, unslaked lime and various auxiliary agent adding container are mixed.
The used waste paper of the present invention is handled through fire prevention when slurrying, becomes refractory fibre, flyash under the effect of activator, and the lateral reactivity of flyash is excited, and the low shortcoming of its early strength is improved; All materials from the hydrophilic hydrophobic that becomes, thereby make lagging material become tool waterproof, fire-resistant materials with function under the effect of water-resisting agent.
The material that the present invention makes; because a large amount of waste paper (accounting for 16.9%) that use; flyash (accounting for 30.12%); the industry policy that not only meets country; the enabling environment protection; and reduced production cost; product is the mixture by the formula ratio metering packing; add water at the construction field (site) and mix slip and just can use, both can directly on body of wall, smear by hand, but mechanically spraying again; product and body of wall energy close adhesion; make thermal insulation layer and body of wall form an organic whole, greatly reduce " heat bridge " effect, the heat-insulating property of product and other physical and mechanical properties are good; except that making wall thermal insulating, also can make roofing; middle cryogenic piping insulation; the tool broad spectrum, product is nontoxic, belongs to green building material.
