Embodiment
For making object of the present invention, technical scheme and advantage clearly, clearly, developing simultaneously referring to accompanying drawing, the present invention is described in more detail for embodiment.
Embodiment 1
Present embodiment discloses a kind of lightweight fiberglass foam cement batten, its structure as shown in Figure 1, comprises Calucium Silicate powder flaggy 100 and foam cement layer 200, and wherein, Calucium Silicate powder flaggy 100 is arranged on foam cement layer 200 surface.Also be provided with gelling enhancer layer 300 between Calucium Silicate powder flaggy 100 and glass fibre foaming cement layer, gelling enhancer layer 300 makes Calucium Silicate powder flaggy be combined more firm with glass fibre foaming cement layer.In the present embodiment, gelling enhancer layer 300 is glue layer, but can adopt other tackiness agents in practical application.
In the present embodiment, the preparation method of lightweight fiberglass foam cement batten as shown in Figure 2, comprises the following steps:
A, get glass fibre, pre-treatment is carried out to glass fibre;
B, other compositions getting glass fibre foaming cement layer mix with pretreated glass fibre, stir, obtain glass fibre foaming cement;
C, calcium silicate board is cut into desired size, coats gelling enhancer on calcium silicate board surface, load mould;
D, in mould, inject lightweight fiberglass foam cement, leave standstill, after glass fibre foaming cement is combined with calcium silicate board, dismounting mould, obtains work in-process light weight cement plate;
E, double finished light cement plate carry out maintenance, obtain finished light cement plate after maintenance.
In steps A, pre-treatment is carried out to glass fibre, comprises the following steps:
S1, get organo-silicon coupling agent and add water and be mixed with the organo-silicon coupling agent aqueous solution;
S2, the organo-silicon coupling agent aqueous solution is sprayed at fiberglass surfacing;
S3, glass fibre to be dried.
In the present embodiment, the organo-silicon coupling agent content in the organo-silicon coupling agent aqueous solution is 5%, and remainder is water.
In the present embodiment, the bake out temperature in step S3 is 120 DEG C.
In step B, the composition of glass fibre foaming cement is calculated according to weight percent, comprises river sand 1%, 108 glue 1%, water reducer 1%, gypsum 10%, trolamine 0.01%, waste stone dust 10%, glass fibre 1%, VAE glue 3%, cement remainder.
In step D, time of repose is 12-48 hour; But in actual production, the time of placing in step D needs temperature and humidity environmentally to judge, and needs the observation foam cement of not timing and the situation of calcium silicate board in put procedure, to ensure that finished cement plate has good character.In the present embodiment, time of repose is 12 hours.
In step e, curing cycle is 28 days.
Glass fibre (English original name is: glassfiber or fiberglass) is a kind of ceramic of excellent performance, and its advantage is good insulating, thermotolerance is strong, erosion resistance good, and physical strength is high, but shortcoming is that property is crisp, and wear resistance is poor.Because the associativity of glass fibre and cement is poor, in foam cement, add glass fibre to have an immense impact on to whole foam cement system, foamed cement structures can become unstable, greatly reduce the work-ing life of foam cement, therefore, in traditional cement board manufactures, generally do not adopt glass fibre as the making component of foam cement.
The present invention utilizes organo-silicon coupling agent to carry out pre-treatment to glass fibre cleverly, enhances the combination stability of glass fibre and cement system, and glass fibre can be perfectly combined with traditional foam cement system; The present invention adopts VAE glue further to increase the degree of adhesion of foam cement system especially, makes it more stable.Although can be good at being combined with traditional foam cement system through pretreated glass fibre, the intensity of foam cement is improved greatly, but the amount of glass fibre must strictly control in foam cement system, otherwise the stability of too much glass fibre meeting havoc foam cement system, makes the life-span of foam cement greatly reduce.
Through the test of many times of contriver, the present embodiment adopt organo-silicon coupling agent content be 5% the organo-silicon coupling agent aqueous solution pre-treatment is carried out to glass fibre, and limiting the content of glass fibre in foam cement system is 1%, add the binding property of the VAE glue increase foam cement system of 3% simultaneously, produce lightweight fiberglass foam cement, not only intensity is high for the lightweight fiberglass foam cement batten utilizing this lightweight fiberglass foam cement to produce, life-span is long, and its resistance toheat is good, even if under 300 DEG C of temperature environments, its intensity does not have considerable change.
This lightweight fiberglass foam cement batten that the present embodiment provides not only has the light advantage of traditional foam cement quality, and its intensity is 3.5 times of traditional foam cement intensity, its bending resistance is excellent, crushing resistance good (ultimate compression strength reaches 12Mpa), shock resistance is good, through 10 impact tests (the cement plate shock test of standard), sheet material two sides is without through slight crack.
