Description
Technical field
The present invention relates to gypsum based composite field, specifically a kind of shock resistance Thistle board.
Background technology
Thistle board is widely used in partition wall and furred ceiling due to superperformances such as light, heat preservation, sound insulation, fire prevention.If with
In special occasions, such as the place that the density of population is high, flow is big may be for wall around when people pass through these areas
Wall is caused to scrape and be hit, and the structure that ordinary gypsum board is made is difficult to bear these instant impacts for coming from the external world, in stress concentration
In the case of, cause plank crack and fracture and other issues occur.
In addition, gypsum is inorganic coagulation material, moisture constantly evaporates in plasterboard drying process, and gypsum crystal drying is received
Contracting, shrinkage stress effect can generate more fine cracks inside gypsum core, influence plank folding intensity, therefore in mechanical strength
It is improved in terms of value limited.Simultaneously in order to improve the shock resistance of Thistle board, different manufacturers take different process.Chinese patent
CN203846681U and CN103938804A discloses one kind and adding the raising of composite fibre grid ribs layer in Thistle board
Plasterboard performance.But the glass is without interface processing, when glass fiber reticular cloth enters Gypsum slurry, due to glass interface
It is untreated, cause bond stress insufficient, when encountering impact force, not can effectively prevent crack generation, therefore with existing invention
It compares, good anti-folding and shock resistance cannot be played the role of on plate property.
Invention content
To solve above-mentioned technical problem, the present invention provides a kind of shock resistance Thistle boards, for addition
Glass fiber reticular cloth carries out the pretreatment of interfacial agents, has good shock resistance and flexural strength.
The present invention solve its technical problem the technical solution adopted is that：
A kind of shock resistance Thistle board, is prepared by the component of following weight proportion：
57-58 parts of building gypsum plaster, 30-40 parts of clear water, 0.4-0.9 parts of modified starch, 0.03-0.06 parts of foaming agent, water-reducing agent
0.2-0.5 parts, alkaline-resisting grid cloth 0.3-0.5 parts of pretreated glass fibre, the longitudinal direction of the alkaline-resisting grid cloth of glass fibre
Fiber is uniformly distributed in transverse fiber in lower planes, and connection is crimped at contact.
The alkaline-resisting grid cloth of pretreated glass fibre is to be located fiberglass gridding cloth in advance by interfacial agents
Reason, the component that the interfacial agents are matched by following weight are prepared：
200 parts of water, industrial 0.5-2 parts of collagen, 10-20 parts of cornstarch, 0.2-0.6 parts of the concentrated sulfuric acid, polyvinyl alcohol 0.1-
0.5 part.
The interfacial agents are made by the steps：
Step a weighs 10-20 parts of cornstarch and is dissolved in 200 parts of water, adds the 0.2-0.6 parts of concentrated sulfuric acids, 40 DEG C-
Under the conditions of 60 DEG C, it is acidified 60min-90min；
Temperature is promoted to 80-90 DEG C by step b, and 0.5-2 parts of industrial collagens are added, react 30min-60min；
Step c, is cooled to room temperature, and 0.1-0.5 parts of polyvinyl alcohol are added, stir evenly,.
The industry collagen is using the combination of one or more of gelatine, gelatin, hide glue.
Amylose in the cornstarch accounts for 25-50%.
The alkaline-resisting grid cloth of glass fibre is set as 1-3 layers.
The present invention was added in the formula of Thistle board through the alkaline-resisting grid cloth of the pretreated glass fibre of interfacial agents, moment
It is combined with Gypsum slurry, preferably reduces plasterboard internal stress variation caused by impact force variation, prevent the extension in crack,
So that plank has been taken into account strength and toughness, improves building gypsum shock resistance 35-40%, flexural strength improves 30% or more, body
More excellent mechanical property is showed；Interfacial agents materials are common, and manufacture craft is simple, are suitble to large-scale promote and apply.
