Technical field
The present invention relates to building material technical fields, particularly belong to a kind of high-strength composite fiber reinforcement honeycomb cement self-insurance Warm filled wall.
Background technique
Building energy conservation reduces environmental pollution and greenhouse effects because it can greatly reduce energy consumption, by many countries Attention.External walls heating insulation is due to being not take up the advantages such as the interior space, and welcomed by the people, existing external heat insulating wall Mainly have and pastes the wall thermal insulatings ways such as styrofoam, on-site casting polyphenyl plate, rock wool board, hard polyurethane foam.The heat insulating ability of these walls Energy, application property, security and stability are different, and some thermal insulation material thermal coefficients are higher, be not suitable for severe cold area heat preservation energy-saving with And the needs of higher power conservation requirement, some fire resistances are poor, are also easy to produce cold bridge, and some construction complexity quality control difficulty are big, have Surface layer cracking resistance problem be relatively difficult to resolve certainly, in addition heat preservation is placed on the outside of building enclosure, inevitably will by rain, snow, strong wind, jelly, Melt, do, is wet, the destruction of pernicious gas and ultraviolet light etc. is also frequently seen unsticking hollowing, surface cracking of outer heat insulation layer etc. recently Qualitative problems of construction also has part engineering that even more serious fire incident occurs.With the propulsion in epoch, the development of technology is right More stringent requirements are proposed for building enclosure, and External Wall heat preservation proposes fire prevention, keeps the temperature, is easy to construct, cheap requirement, with A kind of Full Featured building enclosure is found to meet the needs of social development.Honeycomb cement plate have light weight, good heat insulating, It prevents fires non-ignitable, the advantages of with building with the service life, but honeycomb cement plate the shortcomings that there are intensity is lower, poor ductility.
Summary of the invention
The object of the present invention is to provide a kind of high-strength composite fiber reinforcement honeycomb cement self-heat conserving filled walls, to solve The disadvantages of certainly existing honeycomb cement self-heat conserving filled wall intensity is low, poor ductility.
To solve the above problems, the technical solution used in the present invention is as follows:
A kind of high-strength composite fiber reinforcement honeycomb cement self-heat conserving filled wall, including cement base wall and sealing, the envelope Layer is wrapped in cement base wall outer side and is environmental protection coating material, and the two sides of the cement base wall are respectively provided with one layer of galvanized steel wire netting, The cement base wall is made from the following raw materials in parts by weight: 20-40 parts of quick-hardening cement, 40-80 parts of ordinary cement, waterproofing agent 2- 4 parts, 4-8 parts of foaming agent, 2-4 parts of accelerator, imitative steel fibre 2-4 parts, 0.2-0.4 parts of moisturizer, 30-40 parts of water, foam stabilizer 2-4 Part, 5-10 parts of cement intensifier, 2-4 parts of quick lime, 0.2-0.5 parts of polypropylene fibre.
Further, the cement base wall is made from the following raw materials in parts by weight: 22 parts of quick-hardening cement, ordinary cement 60 Part, 3 parts of waterproofing agent, 6 parts of foaming agent, 3 parts of accelerator, imitative 3 parts of steel fibre, 0.3 part of moisturizer, 35 parts of water, 3 parts of foam stabilizer, water 6 parts of mud reinforcing agent, 3 parts of quick lime, 0.3 part of polypropylene fibre.
Further, the waterproofing agent is inorganic aluminate water-proof agent, and the foaming agent is hydrogen peroxide, and the accelerator is silicic acid Sodium, the moisturizer are carboxymethyl cellulose
Further, the cement intensifier is made from the following raw materials in parts by weight: 6-10 parts of diethylene glycol (DEG), 10-20 parts of malt sugar, the third three 3-5 parts of alcohol, 2-5 parts of triethanolamine, 2-5 parts of anhydrous sodium sulfite,
Further, the cement base wall production method includes the following steps:
S1 is weighed in proportion: quick-hardening cement, ordinary cement, waterproofing agent, accelerator, imitative steel fibre, moisturizer, cement intensifier, Quick lime, polypropylene fibre are uniformly mixed and mud are made;
S2 is added foam stabilizer in S1 cement slurry, is stirring evenly and then adding into foaming agent, is stirred for 1-2min, finally will newly obtain Cement slurry stirring after pour into mold rapidly;
The cement slurry being poured into mold is stood 2-4h foaming by S3;
S4, by after the related cement slurry stand foaming being poured into mold of mold, will be placed into thermostatic curing case in S3, warp Demoulding obtains honeycomb cement block after crossing 4h;
Honeycomb cement block obtained in S4 is divided into cement base wall as required by S5.
Compared with prior art, implementation result of the invention is as follows by the present invention:
A kind of high-strength composite fiber reinforcement honeycomb cement self-heat conserving filled wall of the present invention, passes through the addition of quick-hardening cement The depanning time of the cement base wall can be shortened, cement base strength of wall body can be improved in polypropylene fibre and imitative steel fibre And toughness, while cement intensifier can react to obtain with lime Ca (OH) 2(quick lime with water) react into high-consistency crystal solution, It is not easy to be precipitated, and is not easy bleeding, can reduce drying shrinkage cracking, the wall is with light-weight, fireproof heat insulating performance is good, ageing-resistant, change The advantages that shape coefficient is small, adhesion strength is high, preparation method is simple, waterproof performance is good, and quality is stablized, low cost, social benefit is bright It is aobvious, it is suitble to promote.
