Abstract
The invention relates to a production process of an ultralight cement-based heat-insulation waterproof board, and the board has waterproof, fireproof, heat-insulation and light properties. The production process comprises the following steps: firstly, pouring waterproof rapid-hardening type self-leveling cement mortar at the bottom of a forming die to form a base plane of the board; placing ultralight heat-insulation core layer boards into the forming die and above the base plane after the base plane is formed, and reserving intervals among the ultralight heat-insulation core layer boards and between the ultralight heat-insulation core layer boards and the frames of the forming die according to design; and pouring the waterproof rapid-hardening type self-leveling cement mortar again so as to fill the designed intervals among the ultralight heat-insulation core layer boards and between the ultralight heat-insulation core layer boards and the forming die, and simultaneously forming an upper plane and frames of the heat-insulation water proof board by using the waterproof rapid-hardening type self-leveling cement mortar, thus further forming a closed waterproof heat-insulation board shell.
Description
Technical field
The invention belongs to the building construction field, relate to the inner, external wall insulation and decoration sheet material of building body, particularly a kind of manufacture craft of making the shell thermal-insulating waterproof sheet material that forms with ultralight foam cement and the fast gravity die gravity flowing levelling mortar of waterproof.
Background technology
Raising along with people's living standard, in the city and part counties and districts all develop along the direction of highrise building, the general reinforced concrete frame structure that adopts when building the building body now, adopt the lightweight ash bricks to constitute body of wall simultaneously, after body structure construction in building is finished, begin to carry out the decoration of inside and outside body of wall.State ministry of public security and national house and town and country construction portion issue on January 5th, 2010 " civilian construction outer heat preservation system and decoration of exterior wall fire prevention temporary provisions ", " combustibility of civilian construction heat insulating material for external is preferably the A level to regulation, and should not be lower than the B2 level." " highrise building must use A level fire proofing material more than 50 meters." regulation of the existing executed building energy-saving coefficient 65% of national house and town and country construction portion.Therefore internally, the energy-conservation and environmental protection of outer wall board proposed new requirement, especially for the exterior wall of construction environment and technological requirement complexity.Sheet material also will reach the requirement of insulation and lightweight in fire prevention, waterproof.Because the intensity of ash bricks is low, the outer wall board that unit weight exceeds standard can't be used the straightforward procedure stationary positioned at all on ash bricks, and sheet material is overweight, and the constructor can't construct in the high-altitude at all, and causes construction speed slow.
Along with progress of science and technology, people design with the foam cement material and use as the exterior-wall heat insulation fire-proof board.But the foam cement water resistance is relatively poor, and because dry volume density is lower, causes intensity to descend, and the integral rigidity poor performance can not be as load material.
For the ultralight cement foaming material can be used in building decoration engineering, once have the people outside expanded material, adopt outside technology such as coating.The material that adopts has cement, cement mortar, polymer cement mortar, other organic material; The surface layer about clad that has has added fiberglass gridding cloth or wire gauze; Add cage of reinforcement at the foam cement sandwich layer, coating thickness is thicker, has strengthened the weight of foaming plate, is unfavorable for constructing operation; The construction of clad is manually wiped one's face more, also has plenty of organic or inorganic sheet material is made casing, foams in casing then.Above technology exists problems such as the strength of materials is low, technology is loaded down with trivial details, panel density is big, coefficient of thermal conductivity is high, production efficiency is low, cost height.Problems such as the waterproof of simultaneously all unresolved good vital ultralight cement foaming material and durability.
Summary of the invention
The objective of the invention is to have the requirement that also will reach lightweight in waterproof, fire prevention and the insulation in order to solve exterior-wall heat insulation sheet material in cement based, and the manufacture craft of a kind of ultralight cement based thermal-insulating waterproof plate that designs.At first foam and make the light thermal-insulation core, heat insulation core material has the effect and the certain intensity of fireproof heat insulating.Make the housing of the fast gravity die self-leveling cement of waterproof mortar face as heat insulation core material at the external surface of above core, housing has good waterproof performance, does not ftracture, advantages of high strength, finally forms lightweight, waterproof, does not fire heat preservation plate material.
The present invention for realizing the technical scheme that goal of the invention adopts is, a kind of manufacture craft of ultralight cement based thermal-insulating waterproof plate, comprise preparation ultralight heat preservation core layer in the described technology, and by the processing step of mould at ultralight heat preservation core layer external surface envelope one deck waterproof case, key is: concrete technology comprises following operation:
A, prefabricated ultralight heat preservation core layer plate;
B, the baseplane of in the moulding form of thermal-insulating waterproof plate, adopting the fast gravity die self-leveling cement of waterproof mortar cast formation thermal-insulating waterproof plate;
C, after forming the baseplane, insert ultralight heat preservation core layer plate in the moulding form, on the baseplane, make between the ultralight heat preservation core layer plate and and keep design at interval with the moulding form frame;
D, once more pour into the self-leveling cement filled with mortar between the ultralight heat preservation core layer plate and and moulding form between design at interval, the self-leveling cement mortar forms the last plane of thermal-insulating waterproof plate simultaneously, forms the waterproof case that seals.
The present invention adopts foam cement to make the water-proof heat-insulating slab sandwich layer, the minimum 50kg/m3 that reaches of ultralight heat preservation core layer plate dry volume density, and coefficient of thermal conductivity≤0.035w/m.k can satisfy the standard of building energy-saving 65%, as to make 60mm thickness sheet material unit weight be 9.75kg/m
2, panel density is little, and construction is very easy to; With the external coating of the fast gravity die cement self-leveling mortar of waterproof as heat insulation core material, make external coating have ultra-thin, high-strength, waterproof, fire prevention, cracking resistance, corrosion resistant effect, it is essential to prevent the heat insulation core material water inlet and cause coefficient of thermal conductivity significantly to improve; Set up reinforcement in heat insulation core material, can improve the impact resistance of sheet material, the upper and lower plate face, frame strong bonded that make sheet material have improved globality together, have improved the supporting capacity of surface layer.
The present invention is described in detail below in conjunction with accompanying drawing.
