Abstract

The utility model relates to a reinforced foamed cement board. The facing materials, such as gypsum board paper, craft paper, glass cloth, etc., are used to be the skin, and the light materials, such as foaming agent, cement, fly ash, etc., are used to make a board base body with micro-pores. The interior of the board base body is provided with a reinforcing rib made of material with high tensile strength. The utility model is designed to be either hollow or solid. The utility model has the advantages of light volume weight, high intensity, heat preservation and good sound isolation effect.

Description

Reinforced foamed cement board

The utility model relates to a kind of enhancing foamed cement plate.

At present, be used to be incubated, the non-bearing partition plate of sound insulation is varied.Representative is to strengthen aerated concrete panel.This plate production process complexity, as grinding thin batching, stirring, cast, chemical blowing with large-sized grinder, also to use high-pressure boiler and the maintenance of high pressure resistant steaming still, and adopt strict safety measure could guarantee safety in production, so equipment investment is big, power consumption is high, and production process can not be worked continuously, and the quality of chemical blowing is not easy control or the like.

The purpose of this utility model is to improve the shortcoming of prior art and the insulation that a kind of unit weight is light, intensity is high, production is simple, equipment investment is few, the enhancing foamed cement plate of sound insulation is provided.

The utility model is to realize like this, the plate face is an epidermis with coverlay materials such as gypsum paperboard, brown paper, glass cloth, the board substrate foaming agent, light material such as cement and flyash is made, and has micropore, board substrate inside has the high material of tensile strength to do reinforcement, as glass fibre, plastics, metallic rod etc.At the one or both sides of epidermis and board substrate, one deck adhesive linkage is arranged, be generally the inorganic adhesive material, epidermis and firm the bonding together of board substrate.It is in order to increase the rigidity of plate, to be convenient to be convenient to facing in the demoulding and the use and to handle that epidermis uses gypsum paperboard, brown paper or glass cloth etc.The interpolation reinforcing material is bending resistance and the shock proof performance in order to increase plate in board substrate.Cement in the board substrate is bonding agent, and foaming agent makes micropore in the board substrate, and is heavy with lightened plate floor, and light materials such as flyash are the costs of and reduction plate heavy for lightened plate floor.In order to strengthen insulation, soundproof effect, be convenient to install and increase the strength and stiffness of plate, the utility model can adopt identical two boards plane to bond together with the line that bonding agent misplaces mutually facing to the plane, the thin air layer of one deck being arranged between two plates or be designed to a side is that convex surface, another side are concave surface, the connection types that male and fomale(M﹠F) is complementary.Plate body can be real core, also can adopt hollow design and assembling.Cement also other inorganic coagulation material such as available gypsum substitutes.

The utility model production is simple, production operation cuts into different size continuously, unit weight is light, intensity height, good rigidity, and waterproof, fire prevention, heat preservation and soundproof are effective.

Below in conjunction with accompanying drawing, details are as follows to quote embodiment.

Embodiment 1

The enhancing foamed cement plate of the system of giving thick 25mm, wide 60mm, long 2500mm, its manufacturing process be, the cross section bottom surface of lay brown paper 1, mould is the plane in mould, is the plane in the middle part of the upper bottom surface, and both sides are a downward tapered plane.In mould, pour into a mould with foaming agent, cement, flyash and mix the board substrate 2 that slurry is made,, continue cast then, until being full of mould all restrainting glass fibres 3 along horizontal width apart from adding 13 apart from rising to the 5mm place.At last at plate face inorganic adhesive 4 bonding one deck brown paper 5.The two boards plane that is shaped is bonded together with the line that inorganic adhesive 6 interlaces facing to the plane, in the middle of two plates slim gas-bearing formation 7 of one deck is arranged, this is the utility model hollow core slab.

Embodiment 2

Giving system thickness is the enhancing foamed cement plate of 60mm, wide 600mm, long 3000mm, and its manufacturing process is, selects mould for use, and its two sides one side becomes semicircle outwards protrusion, and a side becomes semicircle inwardly recessed, and the both sides semicircle matches each other.There is an inside inclined-plane at the upper and lower surface middle part for plane, both sides, lay one deck gypsum paperboard 8 in mould, the board substrate 9 that system is mixed by foaming agent, cement, flyash in the mould, on the make, at distance board substrate two surperficial 5mm places all apart from lay reinforcing bar 10, be coated with one deck inorganic adhesive 11 on the plate body surface at last, bonding last layer gypsum paperboard 12.This is that the real core of the utility model strengthens the foamed cement plate.

The utility model board test performance is as follows:

Unit weight 200-600 kilogram/rice ³Thermal conductivity factor 0.06-0.14W/mK.
