Problems solved by technology

[0002] At present, the floors used in buildings include ceramic tiles, solid wood floors and composite boards. Among them, solid wood floors are expensive and have poor performance in terms of moisture resistance and corrosion resistance; ceramic tiles are strong in corrosion resistance, but the surface is too smooth. It is easy to slip and fall on it, and it will also make a lot of noise; the composite board has a wide range of application space because it can combine multiple functions, but how to design and select the material of the composite board is an important factor to realize the required function. link

Embodiment Construction

[0010] Such as figure 1 As shown, the present invention provides a PIR foam cement sandwich panel for construction, including a decorative panel 1, a sound-absorbing panel 2, a shock-absorbing panel 3 and a bottom panel 4 pressed together in sequence, and the panels are bonded by an adhesive to decorate There is a waterproof coating between the board 1 and the sound-absorbing board 2, the decorative board 1 is a high-strength wear-resistant composite board, the shock-absorbing board 3 is a PIR foam board, and the lower surface of the bottom board 4 is rough.

[0011] The full name of PIR is Polyisocyanurate Foam. ". PIR is light in weight, high in strength, and has the function of sound insulation and shock resistance. It can achieve a good shock absorption effect when it is applied to the floor. The sound-absorbing board mainly absorbs the sound generated during the impact process of external objects and the invention. The waterproof coating in between blocks the communicat...

Abstract

The invention provides a PIR foamed cement laminboard for construction. The laminboard comprises a decorative sheet, an acoustical board, a PIR damping sheet and a base board which are sequentially pressed together and bonded through an adhesive, wherein a water-proof coating is arranged between the decorative sheet and the acoustical board, the decorative sheet is a high-strength abrasion resistant composite board, and the lower surface of the base board is rough. The laminboard has a sound absorption function, transmission of vibration can be blocked effectively, and environmental noise pollution is reduced; and the laminboard is firmly connected with the ground after arrangement, and has the advantages of being high in intensity, attractive in appearance, durable, waterproof and moisture-proof.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a floor with functions of sound absorption, heat preservation and shock absorption. Background technique [0002] At present, the floors used in buildings include ceramic tiles, solid wood floors and composite boards. Among them, solid wood floors are expensive and have poor performance in terms of moisture resistance and corrosion resistance; ceramic tiles are strong in corrosion resistance, but the surface is too smooth. It is easy to slip and fall on it, and it will also make a lot of noise; the composite board has a wide range of application space because it can combine multiple functions, but how to design and select the material of the composite board is an important factor to realize the required function. link. In addition, because buildings pay more attention to the insulation effect of walls and roofs, but ignore the insulation effect of the ground, it als...
